25.23 Troubleshooting Supermon problems
The following table describes possible causes of problems with Supermon and provides actions
to correct them.
Corrective actions Cause/Symptom
Perform the appropriate action:
• Ensure that the supermon service is running on the
CMS:
# service supermon status
If not, restart it:
# service supermon restart
• Ensure that the mond daemon is running on all the
managed systems:
# pdsh -a -x `headnode` /etc/init.d/mond
status
Supermon is not running
Use the telnet command to connect on the appropriate
port, port 2710 for Supermon and port 2709 for the mond
daemon. Enter the S command after connection to see
metrics data output. Supermon and mond are running, but there is no activity
Supermon listens on port 2710. The mond daemon listens
on port 2709.
Perform the appropriate action:
• Ensure that sensor data is collected and stored in RRD:
# shownode metrics sensors
• Verify that metric gathering is working correctly:
# cd /opt/hptc/supermon/usr/bin
# ./get_stats -n server -c nodeinfo
# ./get_stats -n server -c sensors
Supermon and mon are running, but sensor data is not
reported
