6 C HAPTER 1WEB APPLICATION MONITOR CHAPTER Overview The Halcyon Web Application Monitor is a powerful tool that is used to monitor, in real-time, the content of live web pages and data within programs that use websites to display information, such as specialist software such as Lawson M3/Movex, JDE or SAP. Typically, these specialist programs are natively installed on an IBM Power i system but cannot be effectively monitored from this platform as they are Javabased applications and Java threads are not visible. However, via an application-specific, vendor provided HMTL Web page, data such as performance statistics, response times, error conditions, active jobs and the like can be displayed. The Halcyon Web Monitor Application can then monitor such web pages and take the actions that would normally be expected of an operations team that were manually monitoring the same information. Because the Web Application Monitor automates the monitoring process, it is available 24/7 and does not miss important information such as a change of status or error condition, and can automatically raise alerts and take actions that would be expected of an operator. The Web Application Monitor is a licensed addition to the monitors used from within Network Server Suite - Central Configuration Manager and operates in the same way in that you create rules, define criteria and set actions that then notify you when criteria are matched. Additional Examples of Usage Other examples of where the Web Application Monitor can be deployed include the monitoring of high availability (HA) systems for out-of-synch objects, alerting if a threshold is reached or breached, or performing pre-determined actions if the temperature of a data center is reaching potential risk levels.

7 Product Limitations The following limitations apply to the use of the Web Application Monitor: The requested URL must be unique. It is not possible to apply the Web Application Monitor to webpages that do not have their own specific URL but remain hidden behind a single web address The Web Application Monitor is unable to process any web pages that contain an embedded login screen although Browser-based pop-ups that require user name and password are supported. The requested data must be contained in an HTML table, definition list ordered list or unordered list within the webpage. 1-2 Network Server Suite

8 C HAPTER 2LICENSING THE WEB APPLICATION CHAPTER MONITOR Licensing the Web Application Monitor The Web Application Monitor does not come as part of the standard release of Network Server Suite and requires an additional license for use. To obtain a new license code that permits use of the Web Application Monitor, please sales@halcyonsoftware.com Please refer to the Network Server Suite Installation Guide or User Reference Guide for instructions on how to apply a product license code. Both of these documents can be accessed from: If the new product code has been generated with the same name as the existing product code and you have purchased enough licenses to cover all of the Windows systems currently operating within Central Configuration Manager, the Web Application Monitor will be automatically visible within each system. If not, then you must assign the Web Application Monitor to each system using the method below: Assigning the Web Application Monitor license: This step is only required if the new license has been generated with a different name to the existing product code license. 1 Select the Systems tab from the left-hand navigation pane of the Central Configuration Manager and left-click on the system name to which the Web Application Monitor is to be licensed. This system must already exist in Device Manager and Central Configuration Manager Console. Please refer to the Network Server Suite Installation Guide for instructions on how to perform these steps.

11 C HAPTER 3DOCUMENTED EXAMPLE OF HOW THE CHAPTER MONITOR WORKS Overview The following example is based around an Enterprise Resource Planning (ERP) system, such as JDE, SAP or Lawson M3/Movex and monitors an HTML web page that shows the current system status. Following this actual example on paper, whilst browsing through the applicable Web Application Monitor dialogs will help you understand the power of this application and will help you familiarize yourself with the process of creating a rule, specifying parameters and applying actions. Due to the nature of the Web Application Monitor software it is not possible to include a generic working example as every system is different. Do not enter the example data into the Web Application Monitor as it is for illustration purposes only. If you have a local example with which you are familiar, you can substitute the data provided in this example, with your own so that you can accurately test the results. Monitoring Requirement For the purpose of this example, one of the statistics that may be used to prove the good health and integrity of the ERP system is that there are 33 active jobs at all times of type Sub:A:Mau. If the number of active jobs falls below or is higher than 33 at any one time, then the Web Application Monitor can notify the relevant support staff and send an SMS to a third-party ERP support team. 3-6 Network Server Suite

12 Adding the Webpage to the Web Application Monitor Once the rule has been given a description, had the periods of activity set and the default alert text applied, the actual criteria can be specified. Select the Criteria Tab and click Add Criteria. The URL of the Web page is entered into the Web Application Monitor, as in Figure 3.1 below. In this example; but you can use an example known to you. Note that using the example provided will result in errors as it is not generic. Figure 3.1 Entering the Web Page URL Without knowing exactly what information is contained on the page it is very difficult to ascertain the criteria on which the rule is actioned. Therefore, the Web Application Monitor contains a utility that allows you to interrogate the data contained within the tables on the Web page, providing table number, row and column headings that can then be used to pinpoint the exact position of the data that you wish to monitor. Browsing Table Data From the Web Application Rule dialog, you can use the Browse Table facility to view the data that is currently held within the Web page URL. Documented Example of How the Monitor Works 3-7

13 To open the table view of the Web page, click Browse Tables. The Browse HTML Table dialog opens, showing the data for the Web page, broken down by table number and row and column headings. Hyperlinks to further information are clearly displayed and can be used from this table to drilldown further into subsequent table data if required. Figure 3.2 Browsing Table Data Tip: It is recommended that you take a printout of the Browse HTML Tables dialog so that you can refer to it when you are entering your rule criteria. Now that you have the required information, you can begin to set the rule criteria. Close the Browse HTML Tables dialog to return to the Web Application Criteria dialog. You can return to the Tables as many times as you wish when setting the rule criteria. Adding Rule Criteria Rule criteria is set through a series of dialogs, each of which is different dependent on the type of parameter being added. A basic set of criteria would typically contain a table number, row identification and the specific data for which you wish to monitor. To begin adding criteria, click Add on the Web Application Criteria dialog. 3-8 Network Server Suite

14 The Select Parameters to Add dialog is displayed. Figure 3.3 Select Parameter to Add From this dialog, you can individually select the Table, Row and Column parameters that pinpoint the exact position of the data that you wish to monitor. From the Browse Table Data, you can see that the table containing the detailed data is headed Table 2 (servers). So the first criteria parameter is to specify that the required data exists in table two. Select the Table parameter from the list and click OK. The Add Table Parameter dialog is displayed. Figure 3.4 Add Table Parameter On this parameter, you simply state: Table Name Number = Value(s) 2 Click OK and the parameter is added to the criteria for the rule. Documented Example of How the Monitor Works 3-9

15 Next, you need to add the parameter that identifies in which row the data is contained. For the purpose of this example, the Server Type; Sub:A:Mau is required for monitoring. Click Add again, to reopen the Select Parameter to Add dialog and this time select the Row parameter. Referring to the Browse Table data, it can be identified that the data required is: Column Type Comparison = Value Sub:A:MAU Click OK to add this parameter. Finally, add the parameter that identifies the number of active jobs running on this server. After checking the Browse Table data again to ensure accuracy, add another Row parameter, this time specifying Column Jobs Comparison <> Value 33 Click OK again and the Web Application Criteria now looks like the screenshot below: Figure 3.5 Completed Rule Criteria Parameters Network Server Suite

16 Click OK on this dialog to complete the entry of the rule criteria. The criteria is now visible on the Add Rule Detail dialog. Adding Actions Although the monitor now knows what data it is monitoring, it does not yet know what actions to take should the number of active jobs not equal 33. You must therefore add at least one action to instruct the rule on a necessary course of action. For the purposes of this example, two actions are added. One to send an alert to your Enterprise Console and a second to send an SMS and to the ERP Escalations team. From the Add Rule Detail dialog, select the Actions tab. This dialog is currently blank as no actions have been added for this rule. Click Add Action to display a list of action from which a choice can be made. Figure 3.6 Select Action The first action required is to Send Enterprise Console Alert. Select this action from the list and click OK. The Console Action dialog is displayed. Retain the defaults on this display and click OK. The Send Enterprise Console Alert is now defined as the first action for this rule. The second action is to Send an Instant Alert Message to the ERP support team notifying them of a problem. Note that this action requires the SMS details of the ERP support team to be entered within the Network Server Suite - Instant Alert - Address Book component. Documented Example of How the Monitor Works 3-11

17 Select the Send Instant Alert Message action and click OK. The Message Action dialog is displayed. Select the recipient and complete the required details (instructions on how to do this are provided in the Network Server Suite User Reference Guide). Click OK to add the action. Figure 3.7 Actions For Rule summary You now have two actions that are automatically taken whenever the number of jobs on Server; Sub:A:MAU are not equal to 33. Click OK on this dialog and the Web Application Monitor is now monitoring the ERP system 24x7 without the need for onsite staff Network Server Suite

18 C HAPTER 4USING THE WEB APPLICATION MONITOR CHAPTER The Web Application Monitor uses the same dialogs and menu options as the other monitors within the Central Configuration Manager. However the criteria options are significantly different and are covered in detail in this chapter. Selecting the Web Application Monitor From the Systems panel of the Central Configuration Manager console, select the system that contains the Web Application Monitor and expand the Server manager view so that all monitors within this system are displayed. Under Business Software Monitors, select the Web Application Monitor. The current settings and defined rules are displayed in the Web Application Monitor panel. This is blank on the first time of opening. Setting the Web Application Monitor to Hold If you wish to stop the current rules from running and producing unwanted actions, for example, when you are trying to resolve an existing issue you can put the Web Application Monitor into a temporary hold state. Note that the interval period is invoked at rule level and so cannot be set independently at this point. Click Hold Monitor to hold all the rules within the monitor from running. Figure 4.1 Hold Monitor option Once the issue has been resolved, click Hold Monitor again to remove the check mark and release all the rules which then start running again. Using the Web Application Monitor 4-13

19 Creating Web Application Rules In order that the Web Application Monitor is active, you must create at least one rule that provides instructions on changes to the web application that are to be monitored and what action(s) to take as a result of those changes occurring. The Web Application Monitor allows you to group rules under the title of a master rule. For example, if a series of rules check a router and subsequent connections, the master rule would first check that the router can be contacted. If not, a single alert is raised for the master rule and subsequent rules in the group are ignored. If the router can be contacted, the other rules are then run in sequence. This prevents multiple alerts being generated in circumstances where a single point of failure is the cause. If you do not define a specific Group then a (default) Group is created and used. Rule Grouping and setting a Master Rule Groups are added at Monitor level. To specify a new group for the Web Application Monitor, click Add Group at the bottom of the display. The Add Group dialog is displayed. Enter a unique Name and Description for the new Group. If you have rules highlighted in the main display when this Group is created you are given the option to move the selected rules to the new group. Setting a Master Rule Once the rules in the Group have been defined, right-click on the rule that you want to define as the master rule for this Group Network Server Suite

20 From the pop-up menu, select Set As Master Rule. A star is placed next to the rule in the main display to identify it as the master rule. This rule is the one that is initially checked for this group. If this fails, an alert is raised and remaining rules are ignored. To remove the master rule setting, select the rule with the star icon beside it and right-click. From the pop-up menu select Clear Master Rule. Master rules have less settings: You are unable to specify when the rule is active. You are unable to use the 'Advanced' settings to, for example, suspend the rule. Only one master rule is allowed per Rule Group. Creating a Rule From within the Web Application Monitor panel, click Add Rule. The Add Rule Detail dialog is displayed. Tabs and pages within this dialog are used to create the detailed settings of the rule. Rule Tab The Rules tab contains three pages which are used to define the description (name), activity, alert detail and suspension settings of the rule. Rule page The rule page is used to determine description and activity settings for this rule and is displayed as the default page. Figure 4.2 Rule settings Using the Web Application Monitor 4-15

21 Rule Settings Description Enter a description to accurately summarize the purpose of this rule. This description is displayed in the summary page at monitor level. Interval The Interval period is used to determine how frequently the Web Application is checked against the criteria listed within this rule. The default setting for new rules is 5 minutes. Seconds, Hours and Days are also acceptable periods of time in this field and can be selected from the dropdown list. Rule Active settings The default settings for these fields set this rule to be active 24 hours a day 7 days a week. They can be overridden if required Days Active These fields are used to select the days on which this rule is active. The default setting is for this rule to be active on every day of the week. Click on any day to remove the check mark and prevent the rule from running on the chosen day. Times Active These fields are used to select the times of day between which this rule is active. The default setting is for this rule to be active over the 24 hour period from 00:00:00 to 23:59:59. If applicable, enter new times between which the rule is active. Invert Time Range If a specific time range has been entered in the Times Active parameters, check this box to indicate the rules is active outside the time range indicated in the From and To parameters. Alert page The Alert page of the Add Rule dialog allows you to specify details of the alert if there is an error connecting to or validating the web page specified for this rule Network Server Suite

22 Figure 4.3 Alert Details Alert Type This field determines the alert type that is displayed in the event of an Error Validating Business Application alert being raised by the rule. This sets the level of severity for any alerts raised by this rule. The Alert Type is automatically set to the Error default although this can be overridden by choosing another selection from the drop-down choice menu. Alert Text Specifies the message text that is used when an alert is raised by this rule. Substitution variables specific to the validation error can be used with free text to compile the alert text. Use Reset to return the Alert Text to the default setting if errors have been made when setting replacement text. An example of how the alert text will be displayed if generated, is shown in the Alert Example field as substitution variables and free text are added in the Alert Text field. See Working with Substitution Variables for more information on the use of Substitution Variables in Network Server Suite. Date and Time Substitution Variables The substitution variables &Date and &Time can be used in the Alert text parameter in the following format: &VAR calc fxxx ; Where: &VAR &DATE or &TIME calc Calculation such as +2d (add 2 days) or =1h30n (+1.5 hrs) f Format of returned value (mm/dd/yyyy or hh:nn) Using the Web Application Monitor 4-17

23 Date and Time Substitution Variable Examples All of the below are based upon 31st Jan 2016 at a.m. &DATE fmm/dd/yyyy ; 01/31/2016 &DATE +2d fmm/dd/yyyy ; 02/02/2016 &DATE fdd-mmm-yyyy ; 31-Jan-2016 &DATE +2d fdd-mmm-yyyy ; 02-Feb-2016 &TIME fhh:nn ; 11:30 &TIME +130n fhh:nn ; 13:00 Advanced page The Advanced page provides options to automatically suspend the rule and reset counters on Startup. Figure 4.4 Advanced Settings Advanced Settings Automatically suspend rule When enabled, this option automatically suspends the rule once triggered either: until the rule has been triggered a specified number of times within a determined time frame. for an amount of time once the rule has been triggered a specified number of times. This can be set as Minutes, Hours or Days so that repetitive alerts are not generated. The default setting is to suspend the rule for 30 minutes when first triggered. Reset Counters on Startup Click to reset counters when the rule restarts, to ensure any historical alerts that are still in the system are ignored: Network Server Suite

24 Criteria options You now need to define the rule specific criteria necessary to generate the alert. The Criteria Summary page, displayed when you select the Criteria tab when adding a rule shows the current criteria setup for this rule. Criteria Summary page From this page, you can Add, Edit and Delete Rule criteria. Each separate criteria is automatically assigned a sequence number when created. To change the criteria sequence order on this page, use the up/down arrows on the right-hand side of this display. Criteria Description and Parameters are also shown as part of this display. Figure 4.5 Criteria Summary page Perform Actions For First/Last/Each Criteria That Triggers When setting rule criteria it is possible to state that actions for the first, last or each criteria that triggers are performed. Using the Web Application Monitor 4-19

25 If this parameter is set to First, the first criteria in the list that triggers has its action performed and subsequent criteria are ignored. If set to Last, every criteria in the list must be triggered before the action is performed and if set to Each, any criteria that are triggered in the rule sequence perform their associated actions. This option only works for all criteria within a single rule. If you only have one criterion set per rule, then this option has no affect. Likewise, the option is not cross rule. Therefore, setting the perform actions for all matching criteria on one rule does not perform actions set on a separate rule. When using the Use Results from Previous Criteria option, you must set the Perform Action For First/Each/Last Criteria That Triggers setting to either Each or Last. Leaving this setting to perform actions when the First criteria is triggered means that the second, and subsequent, criteria are never reached. Example: A CPU, Disk and Memory rule has three different levels of criteria set against the CPU loading to perform three different actions when triggered. 1 If CPU load >= 75% then log only 2 If CPU load >= 85% then Send Enterprise Console Alert 3 If CPU load >= 95% then Send Message The CPU load hits 94% With Perform Actions for First Criteria That Triggers enabled, the first criteria is triggered, the action performed and the rule returns to its monitoring state. With Perform Actions for Each Criteria That Triggers enabled, the first criteria is triggered, the action performed and followed by the subsequent action as it also matches the criteria. With Perform Actions for Last Criteria That Triggers enabled, no action for this rule is performed as the CPU Load percentage did not trigger the last criteria. Adding Rule Criteria Rule criteria determine the Web Application Monitor behavior so it is worth investing time in experimenting with various settings and observing the results. There is the facility to test the current settings at every level so that you can measure the actual results returned against those that you expected and alter the criteria accordingly. At this point, remember that it is not just the specific criteria that you have entered that can affect the results. Changing program settings such as Trigger on First Matching... or Perform Actions on First/Each/Last Criteria That Triggers, can also have an affect on the expected results Network Server Suite

26 On the Rule Criteria summary page, click Add Criteria to open the Web Application Criteria dialog. There are five pages to be completed when adding criteria. Criteria page Settings on this page define the URL of the web page to be monitored and the HTML table parameters within that page that you wish to interrogate. This page also summarizes the current parameters that have already been setup for this rule by providing the name of the parameter as well as the name of the variable by which it can be used in subsequent criteria (if the parameter has been saved as a variable). Figure 4.6 Criteria Settings Web Application Settings URL Upon opening this dialog, this field defaults to the IP Address of the local host system ( ). Override this setting with the URL of the webpage on which you wish to monitor. Before changing any other settings on this page, or beginning to add any criteria, use the Browse Tables facility to interrogate the HTML details of the entered URL. See Web Application Settings for more information. Using the Web Application Monitor 4-21

27 Use Results From Previous Criteria The Use Results From Previous Criteria option can be used to perform actions on the hyper link results generated by the previous criteria in this monitor. For example, if the previous criteria has found that a certain condition exists on a webpage, then the entry in this criteria definition could be used to drill-down further into subsequent pages or tables via a hyper link allowing access to the secondary condition. The previous criteria must have been saved as a variable to allow the use of this functionality. When using this option, you must set the Perform Action For First/Each/Last Criteria That Triggers setting to either Each or Last. Leaving this setting to perform actions when the First criteria is triggered means that the second, and subsequent, criteria are never reached. The previous criteria must include a Row parameter in order that the subsequent drill-down is successful. More than one row can be returned if the specified criteria parameters finds multiple occurrences of the data. When the Use Results From Previous Criteria option is enabled, the URL field changes to Variable so that a previously defined variable can be specified. The criteria summary page also has a graphical indication that subsequent criteria are dependent on the results of this criteria being triggered, but only when the Perform Actions For Last Criteria That Triggers option is selected. See Save As Variable for more information. See Using Hyperlinks in Tables for more information Network Server Suite

28 Timeout Specifies the connection timeout period between the CCM Server and the webpage. The default setting is 5000 milliseconds. The maximum setting is milliseconds. If the timeout period is exceeded then an alert is forwarded to the Enterprise Console informing that a connection between the CCM Server and the intended web page could not be made. HTML Table Parameters Settings These fields define at which point the criteria is triggered and the HTML table elements on which the criteria is defined. Trigger Criteria On This setting allows you to specify at which point the alert is raised. First Matching The alert is triggered on the first matching instance of the criteria found. Each Matching Separate alerts are triggered for each matching instance of the criteria found All A single alert is triggered with the information of up to 50 matching instances of the criteria found Table/Row This field initially applies to tables but if you add row parameters then you can also select whether the criteria is triggered on the first, each or all matching table or row data. This option is not enabled until row parameter data is added. If you use the Use Results From Previous Criteria setting, this option must be set to First Matching Row. This is done automatically if Row is entered as the first parameter in the criteria list, otherwise the change has to be performed manually. Parameters When creating a new rule this table is initially blank. Figure 4.7 Web Application parameter settings Using the Web Application Monitor 4-23

29 Click Add to open the Select Parameter Type To Add dialog from where a parameter selection can be made. As parameters are added, they are displayed in this table, in the order in which they were created (earliest at the bottom). If a parameter has been saved as a variable, the name of the variable is displayed in the second column of this display. Combinations of entered parameters then pinpoint the exact information on the specified webpage on which you are looking to report. See Criteria Parameters for more information. Browse Tables Prior to specifying any detailed criteria, it is recommended that you use the Browse Tables option on this dialog to view the HTML tables contained on the specified URL. By doing this, you can pinpoint the exact information that you wish to monitor. Figure 4.8 Browse HTML Table data (example) Click Browse Tables to retrieve the table data for the entered URL and display the information within the Browse HTML Tables dialog. Each table identified on the page is displayed with number and row/column data that can be used when setting parameter criteria Network Server Suite

30 Additionally if you have the Return Active Links setting within the Advanced Criteria page activated, hyperlinks are also displayed. It is recommended that you take a print of the Browse Table data so that you can refer to it when entering Criteria Parameters. Criteria Parameters Criteria parameters are added from the Web Application Criteria dialog. Click Add to display the Select Parameter to Add dialog. Any of the following seven parameters can be selected and each has its own variables to define its operation. Figure 4.9 Select Parameter to Add Column parameter The Column parameter is used to specify the details of any column contained within the table on which you wish to report. Using the Web Application Monitor 4-25

31 Figure 4.10 Add Column parameter Column Enter either the column name or number from the HTML table on which you wish to report. Comparison Use the comparison field to specify whether the selected column should contain or not contain the subsequent value(s). Does not contain is a useful parameter if you are checking for data that by default is present on the webpage. By selecting this type of parameter, an alert is raised if the entered values are not displayed, allowing you to then investigate the reason. Value(s) Enter one or more values that must be matched when this parameter scans the specified column of an HTML table on the requested webpage. When using this field to Compare Dates, you can use the Alert Variables (see below) to enter a mixture of numbers and date format entries to ensure the correct format is used. If more than one value is specified when entering Column Values, press Enter after each value typed to separate the criteria. Compare Dates Click to enable this setting so that this column criteria is used to check if a date within the table has changed within a given time period. Once enabled, the Format String, Date Offset and Alert Variable settings become active Network Server Suite

32 For example, you can enter 01-&MM-&YYYY (with a Format String parameter entry of DD-MM-YYYY) to represent 1st Day of any month in the year or 01- &DD-&YYYY (with a Format String parameter entry of MM-DD-YYYY) to represent any day in the 1st Month of the year. Alternatively, you can enter the exact value that you wish to search for, i.e. Friday 30 September The information entered as the value must match the one entered in the Format String parameter. Dates that use a single digit, such as Monday 3 October, may not return the required result due to the limitations of the &DD Numeric Date format. Verification of Dates/Times only works if ALL rows for the column to be checked have values in the format specified. For example, the 'Date' column in the following example can be checked; Date Price 01-Jan Feb but the 'Value' column in the following example cannot be checked as some of the values within the column are not dates: Element Value Description My Item Description Date Entered 01/02/2011 Format String Enter the date format EXACTLY as it appears in the column. For example, DD/ MM/YYYY, DDDD MM YYYY or MM:DD:YYYY. This can be used in conjunction with the Value(s) parameter to ensure that the correct format is used. The format entered must match precisely with the contents in the column. Date Offset When using the Compare Dates parameter, use this field to specify the number of days/months/years (either in the future or previously from the date added in the value field) in which a change of date within the column is deemed to have occurred. Alert Variables Use the pre-defined alert variables to build the required value for the date format. (see Value(s) above). Save As Variable Click to enable the saving of this parameter as a variable that can then be used when setting subsequent criteria to drill-down into more information. Enter the name by which you wish this variable to be identified for use when setting subsequent rule criteria. This must be name of the column in which the value was found and entered in the format &columnname. Therefore, if a value was found in a column called Command, you would save the variable as &Command. Using the Web Application Monitor 4-27

33 Click OK to save this Column parameter as part of the rule criteria. See Use Results From Previous Criteria for more information on using previously saved variables. Count parameter This parameter is useful when trying to ascertain if the table contains the expected amount of columns and rows and can be used to determine the following: The table has the correct number of rows/columns The table has more or fewer rows/columns than expected Type Select either Rows or Columns as the type on which count is performed. Comparison Select the comparator against which the count is measured. Count Enter a value that must be matched (or not matched dependent on the comparator used) when this parameter scans a table on the requested webpage. Figure 4.11 Add Count parameter Save As Variable Click to enable the saving of this count parameter as a variable that can then be used when setting subsequent criteria to drill-down into more information. See Use Results From Previous Criteria for more information Network Server Suite

34 Enter the name by which you wish this variable to be identified for use when setting subsequent rule criteria (&Count is recommended). Click OK to save this Count parameter as part of the rule criteria. Ignore parameter Use the Ignore parameter to specify that the Web Application Monitor disregards the first or last number of rows within an HTML table on the requested webpage. This is useful for bypassing table headings and other irrelevant data. This option only applies to Rows and cannot be used with table columns. Figure 4.12 Add Ignore parameter Ignore Specify whether this ignore parameter is for the First or Last number of rows. Rows Enter the number of rows to be ignored. Save As Variable Click to enable the saving of this count parameter as a variable that can then be used when setting subsequent criteria to drill-down into more information. See Use Results From Previous Criteria for more information. Enter the name by which you wish this variable to be identified for use when setting subsequent rule criteria. (&Ignore is recommended) Click OK to save this Ignore parameter as part of the rule criteria. Using the Web Application Monitor 4-29

35 Row parameter The Row parameter is used to specify that a certain value either exists or does not exist within a given row/column combination, allowing you to pinpoint an exact location within the HTML table. Once this parameter has been invoked you are able to select whether the criteria is triggered on matching table or row data. If the row parameter is the first entered parameter for this criteria then this setting is changed automatically. See Trigger Criteria On for more information. Figure 4.13 Add Row parameter Network Server Suite

36 Column/Variable Use this selection to check for any rows that match the entered values in the specified column heading. Therefore If you were searching for Halcyon Software in a column titled Software Vendors, you would enter Software Vendors as the Column/Variable and Halcyon Software as the Value with a comparator of =. Comparison Select the comparator against which the Column/Variable and Value entries are measured. Value(s) Enter one or more values that must be matched when this parameter scans the specified column of an HTML table on the requested webpage. When using this field to Compare Dates, you can use the Alert Variables (see below) to enter a mixture of numbers and date format entries to ensure the correct format is used. For example, you can enter 01-&MM-&YYYY (with a Format String parameter entry of DD-MM-YYYY) to represent 1st Day of any month in the year or 01- &DD-&YYYY (with a Format String parameter entry of MM-DD-YYYY) to represent any day in the 1st Month of the year. Alternatively, you can enter the exact value that you wish to search for, i.e. Friday 30 September However, the information entered as the value must match the one entered in the Format String parameter. Dates that use a single digit, such as Monday 3 October, may not return the required result due to the limitations of the &DD Numeric Date format. If more than one value is specified when entering Column Values, press Enter after each value typed to separate the criteria. Compare Dates Click to enable this setting so that this column criteria is used to check if a date within the table has changed within a given time period. Once enabled, the Format String, Date Offset and Alert Variable settings become active. Format String Enter the date format EXACTLY as it appears in the column. For example, DD/ MM/YYYY, DDDD MM YYYY or MM:DD:YYYY. This can be used in conjunction with the Value(s) parameter to ensure that the correct format is used. The format entered must match precisely with the contents in the column. Date Offset When using the Compare Dates parameter, use this field to specify the number of days/months/years (either in the future or previously from the date added in the value field) in which a change of date within the column is deemed to have occurred. Alert Variables Use the pre-defined alert variables to build the required value for the date format. (see Value(s) above). Using the Web Application Monitor 4-31

37 Treat Non Numeric Column Values As Zero This option allows you to specify whether non-numerical column data is treated as a zero and only applies to columns containing numerical data as any text contained within the column is ignored. With this setting active, if a non-numeric value such as -, is found in the column, then it is replaced with a zero. When the setting is inactive the value is simply left as it was originally defined. Click OK to save this Row parameter as part of the rule criteria. Start From parameter The Start From parameter is used in conjunction with dynamic tables where the data is frequently changing. When this parameter is used, the software remembers the last row that was read in the table and initiates the subsequent search from this point. This allows you to ignore data that has already triggered the criteria. If this parameter is used with a static table then subsequent criteria parameters will not be actioned as there is no actual data on which to search! Figure 4.14 Start From parameter Start From Last Row Read From This setting indicates the direction in which the data is read on the dynamic table. Therefore, if fresh data is entered at the bottom of the table, select Bottom to force subsequent parameters to read data from the saved row onwards in a downwards direction. Likewise, if fresh data is entered at the top of the table select Top to force subsequent parameters to read data from the saved row onwards in a upwards direction. Save As Variable Click to enable the saving of this count parameter as a variable that can then be used when setting subsequent criteria to drill-down into more information. See Use Results From Previous Criteria for more information Network Server Suite

38 Enter the name by which you wish this variable to be identified for use when setting subsequent rule criteria.(&startfrom recommended). Click OK to save this Start From parameter as part of the rule criteria. Table parameter The Table parameter allows you to define a specific HTML table held within the requested webpage, from which data can then be analyzed. Table Name/Number Select the comparator (equals, does not equal, etc.) to specify the method by which the table is identified on the webpage, when used in combination with the entered value(s). Value(s) Enter the name(s) and/or number(s) of tables within the webpage on which the selected comparator searches for matching or non-matching results. Figure 4.15 Table parameter Save As Variable Click to enable the saving of this count parameter as a variable that can then be used when setting subsequent criteria to drill-down into more information. See Use Results From Previous Criteria for more information. Enter the name by which you wish this variable to be identified for use when setting subsequent rule criteria. We recommend the use of the table name or number in the format of &TableName or &TableNumber. Click OK to save this Table parameter as part of the rule criteria. Using the Web Application Monitor 4-33

39 Total parameter The Total parameter allows you to specify that the value of a specific column or specified variable either matches or does not match the specified total value. Figure 4.16 Total parameter Column/Variable Enter the Column Name, Number or previously saved Variable name on which the total action is performed. Comparison Select the comparator against which the Column/Variable and Total entries are measured. Total Specify the total value that the parameter must either match or not match in order to generate an alert. Save As Variable Click to enable the saving of this count parameter as a variable that can then be used when setting subsequent criteria to drill-down into more information. See Use Results From Previous Criteria for more information. Enter the name by which you wish this Total variable to be identified for use when setting subsequent rule criteria. Click OK to save this Total parameter as part of the rule criteria. Alert page When adding rule criteria, the Alert page allows you to specify the level of alert type and alert text that is used in the message generated if the specified criteria is matched and an alert raised Network Server Suite

40 Figure 4.17 Criteria Alert Details Override Rule Default Click to enable the ability to change the default alert settings for this rule criteria. Alert Type The alert type that is displayed in the event of any alert being raised by this criteria. This sets the level of severity for any alerts raised by this criteria. If you have selected to override the rule default setting, you can select an alternative alert type from the drop-down list. Alert Types are set up in Enterprise Server Options Alerts Alert Types. See the Network Server Suite User Reference for more information on the default types and how to create bespoke alert types. Alert Text Specifies the message text that is displayed or sent when an alert is raised by this rule criteria. Substitution Variables can be used with free text to compile the alert text. Use Reset to return the Alert Text to the default setting if errors have been made when setting replacement text. Using the Web Application Monitor 4-35

41 An example of how the alert text will be displayed if generated, is shown in the Alert Example field as substitution variables and free text are added in the Alert Text field. See Working with Substitution Variables for more information on the use of Substitution Variables in Network Server Suite. Date and Time Substitution Variables The substitution variables &Date and &Time can be used in the Alert text parameter in the following format: &VAR calc fxxx ; Where: &VAR &DATE or &TIME calc Calculation such as +2d (add 2 days) or =1h30n (+1.5 hrs) f Format of returned value (mm/dd/yyyy or hh:nn) Date and Time Substitution Variable Examples All of the below are based upon 31st Jan 2016 at a.m. &DATE fmm/dd/yyyy ; 01/31/2016 &DATE +2d fmm/dd/yyyy ; 02/02/2016 &DATE fdd-mmm-yyyy ; 31-Jan-2016 &DATE +2d fdd-mmm-yyyy ; 02-Feb-2016 &TIME fhh:nn ; 11:30 &TIME +130n fhh:nn ; 13:00 Authentication page The authentication page is used to enter the details of any user name and password configuration need to access the requested web server Network Server Suite

42 Figure 4.18 Authentication page URL Authentication Settings These settings specify the User name and Password required to access the requested URL. Use Authentication Click to enable User Name and Password fields for any URL that requires user authentication. The Web Application Monitor supports secure addresses (HTTPS). In order for the connection to an HTTPS address to be successful, the required domain must prefix the user name, for example; halcyon\jsmith, in the User Name parameter. URL Authentication only works with a browser based popup request for user name and password. HTTP pages that embed this information are not supported. User Name Enter the user name required for access to the specified URL. Password Enter the associated password for the specified user name. Proxy Server Settings These settings are used to specify the details of any proxy server that may be needed in order to access the required URL. Using the Web Application Monitor 4-37

43 Use Proxy Server Click to enable subsequent proxy server settings on this dialog. Host/Address Enter the IP address of the proxy server or the host name. User Name Enter the user name required for access to the specified proxy server. Password Enter the associated password for the specified user name. Tables page Figure 4.19 Tables page settings Table Numeric settings The Table Numeric settings allow you to specify the symbols used to define the decimal and thousand separators. The default settings specify that. is used as a decimal separator, for example; and the, is used as the thousand separator, for example; 1,234. Table Display settings The Table Display settings allow you to specify the way in which data is displayed when using the Test facility with Detailed Logging activated. The settings here can also affect the actual information displayed in the Alert Details section of any alert received at the Enterprise Console. See Testing the Criteria settings for more information Network Server Suite

44 Show Empty Columns Click to show columns that do not contain any data when the test results are displayed. Detailed logging must also be activated. Empty columns are also displayed in any table shown in the Details section of the alert when received at the Enterprise Console. If there are a lot of empty columns then viewing of the table might be difficult from within the Alert Details section. Show Empty Rows Click to show rows that do not contain any data when the test results are displayed. Detailed logging must also be activated. Empty Rows are also displayed in any table shown in the Details section of the alert when received at the Enterprise Console. If there are a lot of empty rows then viewing of the table might be difficult from within the Alert Details section. Highlight Matching Rows/Columns Click to show any rows and/or columns that match the entered criteria as being highlighted with a yellow background when the test results are displayed. Detailed logging must also be activated. This is useful if the table contains a large amount of data as it is easy to determine the data in which you are interested. When inactive, any matching rows/columns are not highlighted in the Alert Details section of the alert when received at the Enterprise Console. Only Include Matching Rows Click to show only the rows that match the entered criteria when the test results are displayed. Detailed logging must also be activated. This is useful when working with large tables full of data where you may be only concerned with one or two items of information. Table Scan settings Table scan settings allow you to specify the type of information that is retrieved when the specified URL is interrogated. Unlike the Table Display settings, which operate in test mode, the table scan settings also apply to the live data retrieved. Therefore if you specify that you do not wish to return active links, you are unable to click-through to the originating webpage from the Alert Details section of the Enterprise Console. See Network Server Suite User Reference for more information relating to the display of Alert Details Return Active Links Use this setting to ensure that any data that is retrieved when the criteria is matched is in the form of an active link that allows you to access the originating webpage and/or drill-down into subsequent information. The default setting for this field is enabled. If this field is not enabled, then you will not be able to use hyperlinks to interrogate further tables in subsequent criteria as only static text is returned. Using the Web Application Monitor 4-39

45 Include Tags Types These settings allow to you to select which types of HTML lists are retrieved as part of the webpage interrogation. All are enabled by default. Definition List Ordered list Table Unordered List If you switch off the Table tag type, then any rule criteria that use the table parameter become redundant. Advanced page The Advanced page of the rule criteria is used to define the use of SLA Statistics, Source Device, User Agent and Wildcard Characters. SLA settings SLA Statistic Aside from using the Report Monitoring tool within Network Server Suite to check for performance data on a system, it is also possible to set Service Level Agreement (SLA) flags against the Web Application Monitor when setting rule criteria. These SLA flags can then be used as a reporting mechanism in Halcyon Advanced Reporting Suite using a pre-defined report template that is shipped with the product. If you are setting multiple SLA flags for different criteria, we recommend that you create a Send Enterprise Console alert action so that you can determine which of the SLA criteria has failed. SLA Statistic checking is not affected by the suspension of the rule, (SLA data is still gathered even if the rule is suspended) but is dependent on the time period when the rule is active (SLA data is not gathered outside the times when the rule is active). We recommend that when creating SLA flags within rules, that all SLA criteria are kept together in the same rule that use the Perform Actions For First/Last/Each Criteria That Triggers option, otherwise SLA failures may or may not be indicated correctly. System performance against the specified SLA flags can then be viewed on the SLA Statistics report (automatically included as a Report Template within Advanced Reporting Suite) for this system. See the Advanced Reporting Suite Installation Guide for more information Network Server Suite

46 Figure 4.20 Advanced page settings Source Device settings For any TCP Monitor rule, it is possible to override the source device. For any alerts raised by that criteria, the Device for the alert is shown as the selected Override Source Device rather than the Device that actually performed the check. This allows for faster pinpointing of potential problem diagnosis. Override Source Device Click to enable the Override Source Device functionality. Source Device From the drop-down list, select the device to be used as the source device for any alerts raised by this rule criteria. User Agent settings Under normal circumstances, the user agent string is most commonly used for content negotiation, where the origin server selects suitable content or operating parameters for the response. For example, the User-Agent string might be used by a web server to choose variants based on the known capabilities of a particular version of client software. However, the user agent string is one of the criteria by which Web crawlers may be excluded from accessing certain parts of a web site using the Robots Exclusion Standard. This setting allows you to override the default user agent string with text of your own choice. Using the Web Application Monitor 4-41

47 User Agent String Enter text that replaces the default user agent string applied when visiting webpages defined in this rule. Wildcard Character settings The wildcard characters area is used to define characters which are then used as substitutes for search spans or single characters. Use... As A Substitute For Zero or more Characters Enter the character that you wish to use as a substitute for this search span. The default setting for this field is *. Thus, any entry with Heat* would find Heat, Heats, Heating, Heated and so on. Use... As A Substitute For A Single Character Enter the character you wish to use as a substitute for a single character. The default setting for this field is?. Thus, any entry with Hea? would find Heat, Head, Hear and so on. Testing the Criteria settings Prior to actually creating the rule it is a good idea to test the current settings to ensure that the results are as expected. If not, amendments can then be made to correct the criteria and a retest performed. This routine can be continued repeatedly until you are satisfied with the results. The test applies to the current criteria section that you are currently adding/ editing. If you are at the first entry in the rule criteria list, then the test only applies to this selection and not to subsequent criteria in the list. If you are at the last entry in the rule criteria list, then all the preceding criteria are included in the test. The test options are available at the bottom of the Web Application Criteria dialog, but remember that other factors such as Trigger on First Matching Table/ Row can also influence the test result. Figure 4.21 Test options Local v Remote Testing Test options allow you to run the tests from either the local or remote device. If you run the test locally, you are testing from the machine on which you are creating the rule, typically the machine on which Central Configuration manager is installed. If you run the test remotely, it is run from server agent on the device for which the rule is intended Network Server Suite

48 Detailed Logging Click to enable detailed logging which, when active, returns a full list of the matched criteria, the actual content of the display being dependent on the active settings defined within the Criteria Tables page. The following screen shots show the difference between the test results obtained with having detailed logging turned off or on. Figure 4.22 Without Detailed Logging enabled Using the Web Application Monitor 4-43

49 Figure 4.23 With Detailed Logging enabled Click Test to begin the test with the current criteria parameters. Repeat until the expected result for the entered criteria parameters is returned. Using Hyperlinks in Tables If the table data contains hyperlinks to subsequent information that is pertinent to the original enquiry then it is possible to drill-down into this information by saving the first parameter as a variable and then select Use Results From Previous Criteria with the saved variable to interrogate the table data lying beneath the first hyperlink. There is no limit to the number of hyperlinks that can be progressively used as part of the drill-down process. Return Active Links must be enabled within the Table Scan Settings of the Advanced Criteria page otherwise active hyperlinks are returned as static text. When using hyperlinks to drill down into subsequent HTML pages, the setting for Trigger Criteria On must be set to First Matching and Row rather than First Matching and Table. Example You will need to know the table and row data from both the first and subsequent HTML pages on which you are setting criteria entering parameter details. Part 1: Entering the first criteria 1 Enter the URL of a Web page with which you are familiar and know that you can drill-down into subsequent Web pages and browse the table data Network Server Suite

50 2 Click Add Criteria and add a Table parameter that identifies the required table number and click Save As Variable, entering the name of the variable as & followed by the column name in which the subsequent hyperlink resides. For example &Address. Click OK. 3 Add a subsequent Row parameter that identifies the column name and row data variable that contains the hyperlink. 4 Change the Trigger Criteria On setting to First Matching and Row. 5 Click OK. 6 Click Test, with Detailed Logging activated, to check that data is returned as expected and that the entered criteria was triggered. 7 If successful, click OK to enter this criteria. If not, edit the parameters and retest until successful. Part 2: Entering the second criteria 1 Click Add Criteria and in the Variable field (where you initially entered the URL) enter the name of the Variable that you specified in step 2, above. 2 If not already checked, click Use Results From Previous Criteria. 3 Click Add and add a Row parameter that identifies the column name and row data variable from the HTML page into which you wish to drill-down. 4 Ensure that the Trigger Criteria On setting for this parameter is also set to First Matching and Row. 5 Click OK. 6 Ensure Detailed Logging is still active and click Test again. The result from the first criteria is displayed, but if the row parameter has been successfully entered, the subsequent HTML table and active link is returned beneath. Use the vertical scroll bar on the right of this dialog to view additional data. The drill-down through a Web page to another Web page is complete and you can now set further criteria, drill-down further and set actions that can be activated on the first or last condition being proven. Columns with Multiple Hyperlinks in one row There may be occasions where the required row in the respective column of the table includes more than one hyperlink. In these instances, you must provide specific instructions so that the correct hyperlink is used. Using the Web Application Monitor 4-45

51 Figure 4.24 Example Movex Screenshot In the screenshot above, the end column titled Command has two possible hyperlinks; Lock and Shutdown available as options for most of the row variables. It may be that, if a specific condition exists on a server, such as an incorrect number of jobs running, you may need to take action direct from the Web Application Monitor. By using a specific link, you can be sure that you are taking the correct course of action from the two possible options. To do this, you would create the first rule criteria in the same way as before, to identify the table and row for the server type; Sub:A:MAU. Now add another criteria, ensuring that the Use Results From Previous Criteria option is checked and enter the variable as; & Command.1.link. Now add a new Row parameter with the the parameters as Command and Lock. This tells the Web Application Monitor that you wish to use the 1st link in the column Command. As you are using the results from the previous criteria, the correct row has already been identified. Also note, that the variable is enclosed in quotation marks. Make sure that the Parameters are set to trigger on the first matching Row and save this criteria. When run, the rule knows that if a certain condition exists on this server, it must take the Lock option. in this example, if you wanted the server to be shutdown, you would enter the criteria as; & Command.2.link and change the parameters to Command and Shutdown. Rule Actions The actions tab of the Rule Detail dialog allows you to specify the action that is performed when the criteria parameters are matched and an alert generated. Multiple actions can be defined for each parameter that is triggered. If there is an error in the rule execution, an alert is generated and sent to the Enterprise Console but the associated rule actions are not applied Network Server Suite

52 Actions For Rule Summary page From this page, you can Add, Edit and Delete actions for rule criteria. Figure 4.25 Actions Summary Each separate action is automatically assigned a sequence number when created. To change the sequence in which the actions are performed for this rule, use the up/down arrows on the right-hand side of this display. Action Sequence, Description and Parameters are also shown as part of this display. An icon displayed in the first column of this display, graphically identifies the action to be performed. Adding Actions On the Actions For Rule summary page, click Add Action to open the Select Action dialog. Using the Web Application Monitor 4-47

53 Figure 4.26 Select Action dialog The actions available for use within the Web Application Monitor are the same as those that are available within the general monitoring capabilities of Network Server Suite. The following actions may be selected: Control Service action The Control Service action allows the Web Application Monitor to start/stop/ pause/resume a selected Windows service from those running on the system on which the Web Application Monitor is installed. This option also caters for dependency and stops associated services if required. Figure 4.27 Control Service action Network Server Suite

54 Service Parameters settings Service This allows you to select the service to be controlled by this action. By default, this selection specifies Use Criteria Service, which selects the service specified in the rule criteria as the service on which the action is performed. Alternatively, select Use This Service to select a different service, from those currently available on this device, from the drop-down choice menu. Action Select the action to perform on the service. You can choose from Start, Stop, Pause or Resume. Timeout For all control actions other than Start Service, select the period of time, in seconds, for the selected action to be successful, after which the attempt fails.the default time period is 30 seconds. Stop Dependent Services If the Stop Service action has been selected in the Action parameter, check this option to also stop any other services that are dependent on the selected service running. Click OK to confirm the action. Execute Command action The Execute Command action allows you to execute a specific command, such as running an OS Command or a bespoke script upon the trigger of the rule criteria. Figure 4.28 Command action Using the Web Application Monitor 4-49

55 Log only (no Action) Selecting this option, results in the alert details being stored in the Server.hlf file but no other action is taken. There are no additional parameters to complete when Send Enterprise Console Alert action This action sends the alert to any defined Enterprise Console. The Send Enterprise Console Alert action allows you to include information relating to the alert that if selected then appears in the Alert Details dialog when the alert is opened from within the Enterprise Console. The following information can be included: Result Status Rule Figure 4.29 Console Action Network Server Suite
