5 1 Introduction The ServerView Operations Manager provides you with the Threshold Manager, within which you can use thresholds to monitor one or more of the PRIMERGY servers currently being managed, and any virtual machines running on these servers, from a central management station. For this purpose, you define thresholds for the different performance parameters associated with the server being managed. These parameters are grouped together to form a threshold set that is stored on the server. Here, ServerView agents use the defined thresholds to monitor the performance parameters. If a value exceeds or falls below a threshold, the ServerView Event Manager is notified accordingly. You can use this threshold set, for example, to monitor the utilization of specific server components on a server that is currently being managed, and thus detect resource bottlenecks in good time. The Threshold Manager provides a user-friendly graphical user interface for the creation and assignment of threshold sets to the servers currently being managed. 1.1 Requirements In order to use the Threshold Manager to monitor a server from a central management station, the following requirements must be fulfilled: General requirements (see "General requirements" on page 5). Additional requirements for virtual platforms (see "Additional requirements for virtual platforms" on page 6) General requirements In order to use the Threshold Manager to monitor a server from a central management station, the following requirements must be fulfilled: ServerView Agents as of V 4.90 must be installed on the managed server. ServerView Threshold Manager 5

6 1 Introduction A valid user ID for the managed server must be listed in the user- /password list of ServerView Operations Manager. For further details, please see the ServerView Operations Manager user guide. After ServerView agents are restarted (e.g. after a reboot or after a new installation) it may take 5-10 minutes until a threshold status is reported. If you are upgrading from ServerView Operations Manager lower V4.90 to a higher version, it is not possible to configure or even delete old-style thresholds. In order to remove an old configuration it is therefore recommended to either: Disable Threshold Monitoring before updating ServerView Operations Manager as of V or Uninstall / reinstall ServerView Agents as of A description of the installation of ServerView Operations Manager and ServerView Agents is beyond the scope of this documentation. Their installations are described separately in the ServerView installation manuals Additional requirements for virtual platforms To use the Threshold Manager for virtual platforms it is necessary to configure account information for the virtual system within ServerView VME agents. In order to do so, the following steps are necessary: 1. Create a system user. 2. Add read-only access to VMware API to this user. 3. Add user to the app.config.xml file. The following virtual platforms are supported: VMware ESX Citrix XenServer Xen How to configure the account information for a virtual system is described below using the example of a VMware ESX system. 6 ServerView Threshold Manager

7 1.1 Requirements Create a system user (e.g. for VMware ESX) In our example this user is called "sv_agent". The user for this purpose should be created on VMware ESX host. 1. Create a user using the user add command. For extended security this user has no system login opportunity and is not a member of any linux group. [root@esx4 ~]# cat /etc/group grep sv sv_agent:x:500:sv_agent [root@esx4 ~]# cat /etc/group grep users users:x:100: [root@esx4 ~]# cat /etc/passwd grep sv sv_agent:x:500:500::/home/sv_agent:/sbin/nologin passwd sv_agent The password for this user must be acceptable by VMware ESX. Enter a password that fulfills VMware ESX requirements: A valid password must consist of at least 7 characters. A valid password must meet 3 of the following criteria: at least 1 uppercase letter (A-Z, English) at least 1 lowercase letter (a-z, English) at least 1 base 10 digit (0-9) at least 1 non-alphabetic character (e.g. '!', '$', '#', '%',...) Add read-only access to VMware API for this user 1. Login to vsphere with administrator authority. 2. Click View - Inventory. ServerView Threshold Manager 7

8 1 Introduction In the tree view you see your virtual host. 3. Right-click the host and select Add permission from the drop-down menu. 8 ServerView Threshold Manager

9 1.1 Requirements 4. Select Read-only from the selective list in the Assigned Role section. 5. Select the option Propagate to Child Objects in the Assigned Role section. 6. Click Add... in the Users and Groups section. The Select Users and Groups dialog is displayed. 7. Select the user name sv_agent in the Users and Groups section. 8. Click Add. The name of the selected user is displayed in the Users field. 9. Click OK. The added user s permissions can be checked by visiting the Permissions tab of the Inventory view. Now this username and password could be written into the app.config.xml file instead of root. ServerView Threshold Manager 9

10 1 Introduction Add user to the app.config.xml file 1. Edit the file /etc/srvmagt/vme/etc/app.config.xml. 2. Search for the section titled <authentication>. 3. Fill in user and password information as necessary: e.g. <User>sv_agent</User><Password>pw4SVagent</Password> 4. Save the file. 5. Restart ServerView Agents. Defined threshold values can only be changed if there is a valid user ID in the user/password list of ServerView Operations Manager. This can be any user ID on the managed server, not just the access authorizations in the app.config.xml file. 1.2 Changes since the previous manual This edition of the manual applies to ServerView Threshold Manager V6.20 and replaces the following online manual: ServerView Suite Threshold Manager V6.10, edition October This manual has been updated to reflect the latest software status and offers the following new features: New parameters monitored for physical servers and VM hosts (see "Monitored parameters" on page 15).

14 2 Threshold Manager concept 2 Threshold Manager concept The Threshold Manager enables users to customize threshold monitoring for PRIMERGY servers. Threshold management supports monitoring for three different server types: physical servers virtualization hosts guest systems Each of these three server types comprises a server-type-specific set of parameters that can be monitored using defined thresholds. To start the Threshold Manager, you have to activate the options Enable Performance Monitoring and Enable Threshold Management on the Settings tab. As soon as these options are activated, the Threshold Manager starts monitoring all managed servers (All Servers) using the default templates for the different server types. For how to deactivate threshold monitoring for a single server, see section "Deactivating / activating performance monitoring" on page ServerView Threshold Manager

For example: storageusage - C:\(%) File system usage of drive C:\ storageusage - /boot (%) File system usage of /boot directory Write throughput for mass storage 1) The experience shows that if a system is having memory problems, the available swap space may be full. We therefore decided to take the total of ServerView Threshold Manager 15

16 2 Threshold Manager concept physical memory and swap space as the basic measurement value for memory usage. The percentage is calculated as (used memory + used swap) / (available memory + available swap). Usually, this value will converge to a value given by the relationship between available memory and available swap and thus stay below the default threshold. Only if there is a memory shortage and swap space starts filling up an alert will be triggered Parameters monitored for a VM host Parameter Significance capacityreserved (%) cpuall (%) cpukernel (%) cpumin cpuuser (%) cpuvm (%) memory (%) Amount of memory reserved by the virtual machines Utilization of all physical processors Utilization of all physical processors in kernel mode Resource CPU usage for all virtual machines Utilization of all physical processors in user mode Resource CPU usage for all virtual machines (average) Memory currently in use P P P P P P P P P P P P P P P P P P 16 ServerView Threshold Manager

If the value measured falls below the lower threshold, the system issues an error message with the following status: Warning. upper threshold 1 (Upper Warning). If the value measured exceeds upper threshold 1, the system issues an error message with the following status: Warning. upper threshold 2 (Upper Critical). If the value measured exceeds upper threshold 2, the system issues an error message with the following status: Critical. a measuring interval (Measuring Interval). The measuring interval specifies the time interval (in minutes) between each measurement. It should always be shorter than the threshold ServerView Threshold Manager 19

20 2 Threshold Manager concept interval, so that there are several measurements within a threshold interval before the system issues a message. a threshold interval (Threshold Interval). The threshold interval specifies the period of time (in minutes) for which measurements are averaged and compared against the threshold, so that the system can issue a corresponding message (Normal, Warning or Critical). Therefore, the thresholds prompt the following actions: Value Between 0 and Lower Warning Between Lower Warning and Upper Warning Between Upper Warning and Upper Critical Above Upper Critical Effect Error message with status Warning Error message with status Normal Error message with status Warning Error message with status Critical 20 ServerView Threshold Manager

23 2.3 Definition of a threshold set 2.3 Definition of a threshold set Since you generally want to monitor several server parameters, you simultaneously define all of the thresholds for the parameters to be monitored. The threshold definitions for the parameters to be monitored are grouped together in a set known as the threshold set. There are two ways in which you can define a threshold set: 1. You can define a specific threshold set for one server. This type of definition is known as a server-specific definition. 2. You can assign a name to a threshold set and then save it. You can use this set to assign the entire set of threshold definitions to one server or to a group of servers. These predefined threshold sets are known as templates. The templates are stored and managed in the template area of the Threshold Manager. 2.4 Definition of a template You can define a threshold set for a server type and assign a name to the set. You can then use this set to assign the entire set of threshold definitions to one server or to a group of servers. Such a predefined threshold set is known as a template. Since the range of parameters that can be monitored differ according to the server type (physical server, virtualization host or guest system), there are three template categories (see "Creating a new template" on page 61). ServerView Threshold Manager 23

24 2 Threshold Manager concept 2.5 Definition of a standard template You can define a template as a standard template for a particular server type. In total, you can define three standard templates as follows: 1. a standard template for physical servers 2. a standard template for virtualization hosts 3. a standard template for guest systems (virtual systems) The standard template is then automatically valid for all servers of the relevant type, for which an additional threshold set has yet to be configured (see "Defining a standard template" on page 67). 2.6 Sample templates Sample templates are delivered with the Threshold Manager. The following two sample templates are available for each server type (physical server, virtualization host, and virtual machine): a template for monitoring the load (I/O and CPU) a template for monitoring energy consumption (alarm when the CPU load falls below a certain level) The sample template for monitoring the load is defined as default template for each server type. 24 ServerView Threshold Manager

25 2.6 Sample templates Default templates for physical server (Load1 / Energy1) Figure 3: Load1 Figure 4: Energy1 ServerView Threshold Manager 25

27 2.6 Sample templates Default templates for virtual machines (Load3 / Energy3) Figure 7: Load3 Figure 8: Energy3 ServerView Threshold Manager 27

28 2 Threshold Manager concept 2.7 Ranking of different threshold definitions You can define a server threshold on three different levels: by defining the thresholds specifically for the server by assigning a suitable template by defining a standard template for the relevant server type In other words, you can simultaneously define several definitions for a server. However, only one definition is valid for the server. Here, the ranking is as follows: 1. the server-specific definition 2. the template assigned to the server 3. the standard template for the server type Examples If a template is assigned to a server group, but a server-specific definition already exists for a server in this server group, the server-specific definition continues to remain valid for this server. If a server is added to the server list under the All Servers server group and there is still no special configuration for this server in the Threshold Manager, the threshold is monitored using a standard template for the relevant server type. 28 ServerView Threshold Manager

29 2.7 Ranking of different threshold definitions 3 Threshold Manager main window Figure 9: Threshold Manager Main Window The main window contains the following elements (from top to bottom): The ServerView Suite header. The ServerView Suite menu bars. The work area, which is divided into a navigation bar on the left and an work area on the right. The navigation area on the left contains a tree structure. The view selected here determines the content shown in the work area on the right. If you click Settings, there is no tree structure in the navigation bar on the left.

You use the Servers and Templates tabs to control the content of the tree structure. The selection you make in your tree structure controls the view displayed in the work area on the right. If you click Settings, there is no tree structure in the navigation bar on the left. Servers In the Servers view, the tree structure shows the servers contained in the ServerView server list. The tree structure is divided into two different groups: Group All Servers Groups Significance Predefined server group. The servers listed in this section are all servers which are managed in Operations Manager. Customized server group, which you created with the ServerList application 30 ServerView Threshold Manager

31 3.1 The tree structure The icon that precedes each server shows a composite threshold status of the parameters for which thresholds and monitoring values are defined (see "Values that can be defined for a parameter" on page 19): Icon Significance OK: Average value is between Lower Warning and Upper Warning. Warning: Average value is between 0 and Lower Warning or between Upper Warning and Upper Critical. Critical: Average value is equal or greater than Upper Critical. Unknown: Parameter value is not provided by agent software. Processing: Calculation is in progress. Not Available: There is no connection to the agent. This may also happen due to timeouts in the event of resource shortage. Templates In the Templates view, the tree structure shows existing templates. It contains the All Templates group and three additional subgroups: Group All Templates Significance Predefined template group, which, in turn, contains three additional predefined template groups Physical servers Templates for PRIMERGY servers VMHosts Templates for host systems VMachine Templates for virtual machines ServerView Threshold Manager 31

48 3 Threshold Manager main window 3.6 Settings Figure 18: Settings view In the Settings tab you activate / deactivate the performance monitoring and the threshold management. You open the Settings tab by clicking Settings in the navigation bar on the left. If the option Enable Threshold Management is deactivated, the Servers and Templates buttons are disabled. Enable Performance Monitoring You can activate or deactivate the performance monitoring. If the performance monitoring is deactivated, performance data are no longer collected from the managed servers. As result you cannot see the performance history in the history chart in the Single System View of ServerView Operations Manager. Enable Threshold Management You can activate or deactivate the threshold management. 48 ServerView Threshold Manager

49 3.6 Settings If the threshold management is deactivated, the following Operations Manager activities will be switched off: Threshold data and status are no longer collected from the managed servers and no configuration synchronization is performed. SNMP threshold traps will be ignored by Operations Manager. The Servers and Templates buttons in the navigation area on the left are disabled. IMPORTANT 1. This does not mean that, if the sending of SNMP traps is deactivated on the agent side, Operations Manager will ignore only these traps. In order to fully deactivate threshold traps, please select the target servers in the server list of the Threshold Manager and then click Deactivate. Consider configuring a valid system user account in SVOM - Administration - Users/Passwords before proceeding. Note that the Servers and Templates buttons in the navigation area on the left will be disabled as soon as the threshold management is deactivated. So if you want to deactivate the sending of SNMP traps on the agent side, please do so before deactivating the threshold management. CAUTION This will deactivate the sending of SNMP traps on the agent side for all Operations Manager instances. It is currently not possible to disable the sending of SNMP traps for specific Operations Manager instances. 2. Note that the configuration change (server and/or template parameters, active status for server) does not occur immediately after you click Apply. ServerView Threshold Manager 49

A corresponding table row is displayed for each value in the selected column that coincides with this character string. Figure 20: Customize tab for character strings in the Filter dialog box <column name> column pattern The character string serves as a filter criterion. You can use any alphanumeric characters in the character string, in addition to the following placeholders:? represents a single character * represents any number of characters \ a wildcard character that allows you to filter using the characters * and?. Example: \* shows all rows that contain a single asterisk in the filtered column. You can enter any number of characters as a filter criterion. Filtering by regular expression is not permitted. 52 ServerView Threshold Manager

55 4 Working with the Threshold Manager In order to be able to use thresholds to monitor the performance values of a server, you must define a threshold set for the server at the central management station. You can define threshold sets for the following server types: physical servers virtualization hosts virtual machines or guest systems You can define a threshold set for a specific server or you can use a template to assign a threshold set to the server. You can also define a threshold set as a standard threshold set that is automatically assigned to each server of the same type as long as you have not made any additional definition or assignment. The threshold set is stored on the server. The ServerView agents use the definitions to monitor the performance parameters of the server and to report an event to the central management station when a corresponding event occurs. 4.1 Opening the Threshold Manager There are two ways in which you can open the Threshold Manager in the ServerView Operations Manager: On the start page of the ServerView Operations Manager, choose Event Management/Threshold Manager. In the ServerView menu bar, choose Event Management/Threshold Manager. To start / operate the Threshold Manager, you need the appropriate permissions. As the RBAC (Role-based access control) based user management of the ServerView Suite controls the assignment of permissions to users by means of user roles, please ensure that your user role is equipped with the required privileges. For details see the "User Management in ServerView" user guide. ServerView Threshold Manager 55

To close the Threshold Manager main window, click on the Close icon in the browser window. 4.3 Deactivating / activating Threshold Management Deactivating / activating threshold monitoring for a single server For modifying threshold monitoring, threshold management has to be enabled (see "Deactivating / activating Threshold Management" on page 56). 1. In the navigation bar on the left, switch to the Servers view. 2. Select All Servers in the tree structure. 3. In the work area on the right, select the server(s) you want to modify. 4. To deactivate threshold monitoring for the selected server(s), click Deactivate. To activate threshold monitoring for the selected server(s), click Activate. 56 ServerView Threshold Manager

57 4.3 Deactivating / activating Threshold Management Deactivating / activating threshold management for all server 1. In the navigation bar on the left, switch to the Settings tab. 2. To deactivate threshold management, deselect the Enable Threshold Management option. To activate threshold management, select the Enable Threshold Management option. 3. Click Apply to confirm the change. If the option Enable Threshold Management is deactivated, threshold data are no longer collected from the managed servers and the Servers and Templates tabs are locked and not available Disable one parameter of a single server To disable one parameter of a single server, set both Measuring Interval and Threshold Interval to 0, e. g. for a server-specific threshold set: 1. In the navigation bar on the left, switch to the Servers view. 2. In the tree structure, select the server for which you want to disable one parameter. The view for the selected server is then displayed in the work area on the right. 3. In the table, enter the 0 for Measuring Interval and Threshold Interval in the line of the relevant parameter.

To activate performance monitoring for all managed servers, select the Enable Performance Monitoring option. 3. Click Apply to confirm the change. If the performance monitoring is deactivated, performance data is no longer collected from the managed servers. As result you cannot see the performance history in the history chart in the Single System View of ServerView Operations Manager. 4.5 Creating server-specific threshold sets You can define a server-specific threshold set for a server and use it to monitor the performance parameters associated with this server. There are two ways in which you can define a server-specific threshold set: You define a new server-specific threshold set for the server. You define a server-specific threshold set that is based on an existing template Defining a new threshold set You can define a specific threshold set for a server. 1. In the navigation bar on the left, switch to the Servers view. 2. In the tree structure, select the server for which you want to create a server-specific threshold set.
