zhrmSaProcess Group Maintenance
zhrmSaProcess Group Maintenance
The zhrmSaProcess group values are updated:
•
At subagent startup time. The values of MIB objects associated with startup
parameters and startup process attributes are initialized.
•
The counters that tally the requests handled by the subagent as well as the values
of zhrmSaCpuTime and zhrmSaHeapCurrent are updated as requests are
received.
•
When a request is received from an SNMP manager to change the subagent’s
process priority. The value of zhrmSaPri does not persist after the subagent stops.
The next time the subagent starts, this object is assigned the subagent priority
specified at invocation.
•
When a request is received from an SNMP manager to enable or disable software
group value maintenance. When one of the refresh timers (-s or -d) runs down or
when the value of zhrmStableRefreshNow or zhrmDynamicRefreshNow is set to 1:
°
A change from 1 to 0 deletes all the software group values.
°
A change from 0 to 1 creates software group values.
•
When the value of zhrmSwitchToBackupNow is set to 1. If a backup process
exists, the subagent’s backup process takes over, refreshing all values in the
subagent’s MIB before handling SNMP manager requests. After takeover is
complete, the subagent sets the value of zhrmSwitchToBackupNow to 0.
•
When a request is received from an SNMP manager to enable or disable the
monitoring of the NonStop Kernel Guardian or OSS personality.
