Explanation: MONITOR is an optional parameter that specifies which informational messages DFSMShsm is to print at the system console, and the values DFSMShsm is to use for monitoring space in the journal and control data sets.
SMS relationship: Parameter has the same meaning when applied to SMS-managed or non-SMS-managed DASD volumes or data sets.
SETSYS default: None.
DFSMShsm default: If you do not specify this parameter on any SETSYS command, the DFSMShsm default is 80%. No messages are printed to the console about space used during volume processing. No messages are printed to the console from DFSMShsm commands read from the ARCCMDxx parmlib member during DFSMShsm initialization.
