VM:Spool lets you monitor the use of spool space on your system by setting up thresholds at which you want to be notified about spool-space usage.
VM:Spool sends messages to inform you when spool-space usage has already reached the level that you identified or when it will soon reach your threshold. The MONITOR record in the VM:Spool configuration file controls spool-space monitoring.
The parameters on the MONITOR record specify:
VM:Spool observes the amount of spool space being used at WAITTIME intervals, combines its last four observations, and calculates spool-space usage trends. If the current trend is toward increasing spool-space usage, VM:Spool projects how soon spool space will reach your defined threshold (SPOOLFUL parameter) if the current trend continues. If VM:Spool estimates that spool space will reach this threshold within the amount of time you specified on the WARNTIME parameter, VM:Spool sends a warning message to users identified on the MONOPER record. User IDs at other RSCS nodes can receive the messages also.
