Collector for Disk, Memory, CPU and Network Load Monitoring

The technical name of the Collector for Disk, Memory, CPU and Network Load Monitoring is /DVD/MON_CL_COL_MEM_CPU_LAN.

This collector collects information about disks, memory, CPU and network load for an SAP instance running within an operating system. Bottlenecks in these areas can significantly affect SAP system performance. The operating system collects these resources by using the operating system collector SAPOSCOL, which must be running on the monitored system to be able to monitor the KPIs listed below. You can use the Operating System Monitor to check if the operating system collector SAPOSCOL is running on the system. If the collector SAPOSCOL is not configured or running properly on the SAP instance, you might receive one of the following warning messages when monitoring relevant KPIs:

  1. Wrong address of shared memory on the remote host.

  2. Operating system collector is not running on the host.

  3. Shared memory is not available.

  4. Operating system collector is busy. SAPOSCOL writes to the shared memory.

  5. No network collector (RMON-MIB) is running.

  6. Operating System Monitor raises the error <ERROR> when calling <FUNCTION_NAME>.

If any of the above mentioned messages occurs during the monitoring, check with your Basis team first whether the operating system collector SAPOSCOL is running on the monitored SAP system as expected.
