Improved Monitoring and Supportability
Improved Monitoring and Supportability Enhanced Performance tabs Filter to hide idle sessions, as well as sessions originating in the Administration editor or other applications in the SAP HANA studio It is now possible to hide different session types from the Threads, Sessions, and Blocked Transactions tabs. Each option can be selected from the drop-down menu Hide Sessions. If an option is selected, a new SQL statement is executed to display only the filtered rows. This filter does not only operate at the display level. When an option is selected, the database is queried again for the relevant sessions. 2013 SAP AG. All rights reserved. Public 6
Improved Monitoring and Supportability Enhanced Performance tabs Easier navigation between the Threads, Sessions, and Blocked Transactions tabs It is now possible to navigate between the Threads, Sessions, and Blocked Transactions tabs by using the connection ID. This functionality is available from the context menu (Navigate To). On the Threads tab, it is possible to navigate from/to callee/caller by using the thread ID. On the Sessions tab, it is possible to navigate to the connection that is blocking the selected connection. The application information (name and user) that is available on the Threads, Sessions and Blocked Transactions tabs can also be used to open a pre-configured dialog for the SQL, performance, and expensive statement traces. 2013 SAP AG.

Improved Monitoring and Supportability New monitoring editors Resource Utilization The new Resource Utilization Statistics editor enables you to visualize and explore the usage history of the following key system resources: CPU Memory Disk The editor can help to analyze bottlenecks, identify patterns, and forecast requirements. The editor can be opened via the contextmenu of the specific SAP HANA system. 2013 SAP AG. All rights reserved. Public 12
Improved Monitoring and Supportability New monitoring editors Memory Allocation Statistics 1/2 The new Memory Allocation Statistics editor enables you to visualize and explore the memory allocation of every service. In the Administration editor, choose the Landscape > Services tab. Right-click the service whose allocation history you want to investigate and choose Memory Allocation Statistics 1 2 3 4 The following information is displayed in screen areas identified above: 1. The components of the selected service listed in descending order of current used memory (default) 2. Current breakdown of SAP HANA used memory displayed as a pie chart 3. Allocators of the selected component listed in descending order of current used inclusive memory (default) 4. Current breakdown of memory usage of the 10 highest consuming allocators displayed as a pie chart 2013 SAP AG. All rights reserved. Public 13
Improved Monitoring and Supportability New monitoring editors Memory Allocation Statistics 2/2 Analyze the used memory history of the component and its allocators by enabling the history graph (Show Graph) and exploring the data. Several options are available, for example: To change the visualized time period, adjust the From/To values. To visualize the memory usage of individual allocators over the same time period as the selected component, simply select them in the allocators table. To see time-specific values, move the mouse over the graph. To see the visualized values in table format, choose (Show history data in a table) 2013 SAP AG. All rights reserved. Public 14
Improved Monitoring and Supportability New summary section on Alerts tab The summary header on the Alerts tab shows the total number of current alerts by priority and the corresponding list of alerts Previous Alerts Tab New Alerts Tab 2013 SAP AG. All rights reserved. Public 15
Improved Monitoring and Supportability Enhanced trace configuration In the Trace Configuration dialog for the Database, User- Specific, and End-to End Traces, conflicts between different configuration layers are indicated with an information icon and mouse-over text. 2013 SAP AG.

Additional Features Statistics Service New implementation design The new statistics service design leads to performance and flexibility improvements The statistics server is the component of the SAP HANA database that provides internal monitoring functions. It continuously collects information about system status, performance, and resource usage, and issues alerts in the event of problems. As of SPS 07, it is possible to switch to a new mechanism whereby data collection and alerting are implemented through the execution of SQLScript procedures. This has the following advantages: The statistics server component is no longer required. By replacing the statistics server with internal procedure calls, overall system performance is improved with reduced disk usage, memory usage, and data transfer. The statisticsserver.ini properties file is no longer required to contain all configuration information relating to data collection and alerting. Instead this information is contained in new tables in the _SYS_STATISTICS schema. This increases the overall flexibility with which data collection and alerting can be configured. For example, data collectors and checks can be scheduled more flexibly, new collectors and checks can be added more easily, and data collectors and checks can be deactivated. For more information about how to migrate to the new mechanism after an upgrade, see SAP Note 1917938 2013 SAP AG. All rights reserved. Public 20
Additional Features Statistics service additional lock statistics The statistics service now collects information about lock statistics into the following tables: HOST_OBJECT_LOCK_STATISTICS HOST_OBJECT_LOCKS HOST_RECORD_LOCKS The table HOST_BLOCKED_TRANSACTIONS has been enhanced to include connection and application information. 2013 SAP AG. All rights reserved. Public 21
Additional Features SAP HANA system logoff and logon New user logoff and logon feature with configurable startup behavior The user can logoff actively from an SAP HANA system via the context menu. Every connection (JDBC/HTTP) is closed after the user executes the Log Off on a selected system (1). If no connection is established, the context menu provides the possibility to logon to a system or delete it (2). The start-up behavior of the SAP HANA studio can be configured. Under Windows > Preferences the user can decide to restore the logged-on/logged-off status of systems on startup (3). 1 2 3 2013 SAP AG. All rights reserved. Public 22
Additional Features Link to centrally-stored archive of SAP HANA systems New feature that allows users to connect efficiently to multiple SAP HANA systems A centrally-stored archive of SAP HANA systems is an efficient way to deploy system information to all users of the SAP HANA studio. It avoids users having to obtain the connection details of all systems individually and then having to add them all individually. One user can manage the list of all systems in a centrally-accessible archive (via File > Export > SAP HANA > Landscape) Other users can then simply link to this archive (read-only mode) 1 2. Specify the link details: a) Link name b) Path to the system archive containing the system information 2 a) b) 1. In the context menu of the Systems view, choose Add System Archive Link. c) Optional: A folder in the SAP HANA Systems view 3. Choose Finish. c) 3 2013 SAP AG. All rights reserved. Public 23
