  • What are the functions of SAPOSCOL ?

SAPOSCOL is an operating system collector. It is a standalone program that runs in operating system background.

SAPOSCOL collects data about operating system resources like

  • CPU Utilization
  • Usage of Physical Memory
  • Usage of Virtual Memory
  • Usage of filesytems
  • Usage of Physical disks
  • Usage of running processes

SAPOSCOL runs exactly once per host and runs independently of the sap system.

By default, SAPOSCOL collects data every 10seconds and records it. It also records the hourly average statistics for the last 24hours in shared memory. This data will be fetched by background job “SAP_COLLECTOR_FOR_PERFORMANCE” and writes it to the MONI performance database table.
