clstrmond - The Performance Manager metrics server for TruCluster
/usr/opt/pm/scripts/clstrmond [ start | stop ]
The Performance Manager (PM) metrics server for TruCluster (clstrmond) is a UNIX daemon process that provides TruCluster-related metrics on request by the PM GUI (pmgr(1)) and other clients.
The clstrmond metrics server supports the Digital UNIX extensible SNMP agent mechanism (eSNMP). In particular, clstrmond will operate as an eSNMP subagent when the Digital UNIX extensible SNMP agent (snmpd) is running.
In addition, the clstrmond metrics server listens for SNMP requests on a private UDP port. Besides accepting SNMPv1 requests, the private port also supports the "SNMPv2 classic" GET-BULK request for efficient bulk data transfer (using noAuth/noPriv security). The pmgr(1) and getbulk(1) programs require this capability.
The MIB (management information base) variables implemented by clstrmond can be found in the file /usr/opt/pm/data/pm-mib.
The clstrmond metrics server automatically starts after a successful installation of Performance Manager and when a node is rebooted. If the metrics server is not running on a node, it may have failed to start, been explicitly stopped, or crashed; see the metrics server log file, /var/opt/pm/log/clstrmond.log, for the possible indications as to the cause.
The specific UDP port number that the clstrmond metrics server uses as its private SNMP port is specified at installation time and stored in the /etc/services file as the "clstrmond-snmp" service.
To see if clstrmond is running, issue the following command:
ps awx | grep clstrmond
If the metrics server is running, you should see output similar to the
329 ?? S < 0:16.02 bin/clstrmond
292 ttyp1 S + 0:00.03 grep clstrmond
If you need to start the metrics server, issue the
command in a
account with the
/usr/opt/pm/scripts/clstrmond start To stop the metrics server, issue the command with the argument:
/usr/opt/pm/scripts/clstrmond stop The Performance Manager metrics server for TruCluster runs with and set to null, and its working directory set to
must be started in a account.
