Operating System Collector SAPOSCOL
The operating system collector SAPOSCOL is a stand-alone program that runs in the operating system background. It runs independently of SAP instances exactly once per monitored host. SAPOSCOL collects data about operating system resources, including:
-
Usage of virtual and physical memory
-
CPU Utilization
-
Utilization of physical disks and file systems
-
Resource usage of running processes
SAPOSCOL makes the data available using a segment of the shared memory for various applications and all SAP instances on a host. A NetWeaver management agent or a dialog work process reads the data from the shared memory. You can display the data in various monitoring architecture monitors or in the operating system monitor (transaction OS06). If the operating system data is read and sent by agents, you can display operating system data for any hosts in a central system.
Features
The program SAPOSCOL is delivered with every SAP system, but is not restricted to SAP systems. The special features of the program are:
-
SAPOSCOL runs exactly once on each host.
-
SAPOSCOL runs independently of the SAP system.
By default, SAPOSCOL collects the current data every ten seconds and records it, and records the hourly averages for the last 24 hours.
Another background job, SAP_COLLECTOR_FOR_PERFORMANCE, takes performance data for the last 24 hours from the shared memory and writes it to the MONI performance database. You can compare this data for one or more hosts.
