Monitoring Background Processing Alerts 

Use

Monitor the status of background processing in your SAP System with the CCMS alert monitor, Transaction RZ20.

Procedure

  1. Start the alert monitor by calling Transaction RZ20 or by choosing CCMS ® Control/Monitoring ® Alert Monitor.
  2. On the CCMS Monitor Sets screen, expand the SAP CCMS Monitor Templates monitor set.
  3. In the list of monitors, start the Background Processing monitor. To do this, position the cursor on the Background Processing monitor and choose Load monitor.

The Background Processing monitor displays both systemwide indicators of background performance and three kinds of monitoring information for each SAP instance offering background processing.

The table below provides further information about the contents of the monitor.

Explanation

App Server-Specific or
Systemwide

Utilization

Percentage of the available background processing capacity currently in use. This value is normalized across the number of background work processes. Alerts are based on average values over time.

Example: A server with three background processes and 90% utilization has had all three work processes in use an average of 90% of the time.

App Server-Specific

Server-specific queue length

The number of jobs that are released and eligible to run but which have no free background work processes.

Utilization and Server-specific queue length together show whether there is a serious shortfall in background processing capacity.

High utilization and low queue length are optimal.

High utilization and high queue length show that your system has not been able to satisfy background processing requirements during the alert time period.

High utilization can quickly lead to queue length problems. If the monitor shows repeatedly high utilization (> 90%), you should increase background capacity.

App Server-Specific

Aborted jobs

Individual jobs that terminated abnormally. A separate red alert is generated for each aborted job.

App Server-Specific

Systemwide queue length

The number of jobs that are ready and eligible to run but which have no free background work processes, averaged across all background servers.

Systemwide queue length gives you a single overview statistic for background processing in your system. For example, even if one background server is having trouble, a low systemwide queue length shows that the problem is specific to a particular server.
