Commands used to monitor CSM

Networking on z/OS

Use the DISPLAY NET,CSM command to monitor CSM.

CSM and VTAM buffer usage can be monitored using the following commands.
D NET,CSM
D NET,CSM,OWNERID=ALL
You can use the following display commands for monitoring storage:
D NET,BFRUSE,BUFFER=SHORT
D NET,STORUSE

Figure 1 shows the command output of a DISPLAY NET,CSM command.
