“SAP OS monitor has probably stopped. The OS information may be incomplete or missing.”

Netweaver administrator is not getting the information about saposcol’s availability from saposcol itself, but from CCMS agents By CCMS agent I mean sapstartsrv process,which has built-in CCMS agent. CCMS agent looks to it’s own shared memory and provides them, if they are available. Asynchronously from this, CCMS agent is regulary downloading the information from saposcol’s shared memory.

All CCMS agents can copy data from the SAPOSCOL shared memory segment to the CCMS monitoring segment and transfer it to a central monitoring system.
