IT Performance Reporting

Use

With IT Performance Reporting, you can centrally display the development over time of the most important monitoring data for your monitored systems in order to identify problems early, and to obtain an overview of the utilization and performance of your systems.

The performance values are taken from the CCMS monitoring infrastructure; you can display this information in the alert monitor, among other places. For IT Performance Reporting, the most important nodes were selected, and seven reports have been created that provide you with a quick and extensive overview of the performance and workload of your monitored systems. In IT Performance Reporting, you can display data from all of the systems that are registered in the monitoring infrastructure. This applies for both AS ABAP and for AS Java, and for various databases.

There are various time periods available to you in the reports – from the current day to the previous year, so that you can obtain an overview both of the current situation and of the long-term development of the performance values. The values are automatically displayed in an appropriate granularity for each of these time periods.

The configuration is largely automatic (more information: Setting Up IT Performance Reporting); it ensures that all of the values that you can display are stored in the required time resolution. Older data is also automatically reorganized into lower resolutions and ultimately deleted, so that the storage requirements of the performance data in BI do not grow unreasonably large.

Integration

IT Performance Reporting is part of the System Monitoring work center in Solution Manager.

Prerequisites

You have performed the relevant setup (more information: Setting Up IT Performance Reporting).

Features

To call IT Performance reporting, choose Reporting in the navigation bar of the System Monitoring work center, and choose the IT Performance Reporting button.

The reports are displayed in a new window. The following seven reports are available to you, grouped by the topic areas Availability, Performance, and Usage:

Area	Reports
Availability	Instance Availability
Performance	Workload Overview Users Logged On Server Utilization(CPU, Filesystem) Database Utilization
Utilization	Java Sessions & Threads Java Garbage Collection

Common to all of the reports is a bar at the top of the window, in which you can select the report itself, the time period, and the system for which you want to display data:

Dropdown List Box	Notes
Report	Choose the report to be displayed here. Note that you must select a report and not an area.
Interval	Choose the time period that you want to display in the report. By choosing the time period, you also define the time scale; for example, for the time period Last Week, the performance values are displayed in a resolution of days.
System Name	You define here the systems for which you want to display data. The entry (All) is also available to you. The system list contains all systems that are registered in the monitoring infrastructure of the central monitoring system. Nevertheless, it is possible that no values are available for a particular report or a particular period – in this case, the system displays the message No applicable data found.

The following reports are available to you:

● Instance Availability

This report displays the availability of the instances that are monitored by the monitoring infrastructure. Planned periods of unavailability for these instances are also shown. You can filter both by instance type and by the individual instances.

An ABAP instance is regarded as available if its dispatcher is running; a Java instance is regarded as available, if the Java Startup Framework reports the instance as available.

The selected availabilities are displayed both graphically and as a table. In the tabular display, the availability in the displayed periods is highlighted in red if the availability is below 99 percent. If the availability is between 99 and 99.9 percent, the value is highlighted in yellow.

Note

Note the following prerequisites, depending on the instance type:

Instance Type	Prerequisites
ABAP	The instance must be monitored with a CCMS agent SAPCCM4X.
Java	The instance must be of at least release status SAP NetWeaver 7.10.
TREX	The instance must be of at least release status SAP NetWeaver 7.10.
liveCache	You have activated the monitoring of the database KPIs in accordance with SAP Note 1068204.

● Workload Overview

This report graphically displays the number of users logged on and the average response time. You can filter both by instance type and by the individual instances. This report always displays the average value for all selected instances.

● Users Logged On

This report graphically displays the number of users logged on, and shows both the average value and the maximum value of the maximum value for the time period selected in each case. You can again filter both by instance type and by the individual instances.

By default, this report displays the average value for all selected instances. However, you can also display the individual values for the instances, by pressing the relevant pushbutton. Note, however, that the graphical display can quickly become unclear (especially if you select a large number of instances).The report also displays the number of users and dialog steps under User Activity ABAP/Java. These values are originally taken from the statistical data (ABAP) and the Distributed Statistics Records (Java).

● Server Utilization (CPU, File System)

The report shows the average CPU utilization graphically for all hosts on which instances of the selected system are running. The value relates to the general CPU utilization of the host, not to the CPU utilization due to a particular instance.

The utilization of all file systems on the above hosts is also shown in a table, both as a percentage and as free disk space in megabytes. Since the number of file systems on a host can become very large, particularly under UNIX, by default, only file systems that are at least 80% occupied are displayed. File systems that are over 90% are highlighted in red.

● Database Utilization

This report displays the size and growth of the databases for the selected systems. Note that you must have activated the monitoring of the database KPIs in accordance with SAP Note 1068204 to be able to see values in the report.

● Java Sessions & Threads

This report, together with the following report, displays the most important information about the monitored SAP NetWeaver 7.10 Java instances. This report shows, in two graphics, the average number of different sessions and the number of active and long-running threads.

● Java Garbage Collection

This report shows the two most important performance values about garbage collections for Java instances: the memory released per minute, and the percentage of time during which a garbage collection is running for the relevant server process.

Technical Background

The values displayed in IT Performance Reporting originally come from the CCMS monitoring infrastructure. It can be of interest to experts in this infrastructure to know which MTE classes are displayed in the reports:

Report	Displayed Value	MTE Class

Instance Availability	liveCache Availability	DB_KPI_availability_pfcl_LVC
Workload Overview	ABAP: Users Logged On	R3UsersLoggedIn
	Java: Users Logged On	SessMgmt.LoggedInUsersCount
	ABAP: Response Time	R3DialogResponseTime
