Reducing the CPU Load Caused by SAPOSCOL
Context
SAPOSCOL can use a high proportion of operating system resources, as it periodically collects data from the operating system. Which data requires the most resources during collection depends on the operating system. You have the following options to minimize the CPU usage of SAPOSCOL:
Procedure
-
Delete the Detail Selection
You can control the collection of data by SAPOSCOL by having certain data, the collection of which has a particularly high influence on the performance, collected less frequently. Which data belongs to this group depends on the operating system of the monitored host:
By default, detail selection is set ( Details required pushbutton in the operating system monitor; command detailson in dialog mode). To remove detail selection, choose Details off in the operating system monitor, or enter the command detailsoff in the dialog mode. This setting applies universally.
-
Use the Idle Mode of SAPOSCOL
If the data is not read from the shared memory during a period of five minutes, SAPOSCOL switches from normal mode to idle mode. In this mode, the collector collects data every minute instead of every ten seconds. This is sufficient for a well-founded hourly average value. If a process reads data from the shared memory during idle mode, SAPOSCOL switches back to normal mode.
