The following table describes possible causes of problems with the Performance Dashboard tool
and provides actions to correct them.
Corrective Actions Cause/Symptom
Perform the appropriate action:
• Restart the Performance Dashboard tool.
• Determine if Nagios is collecting data.
The Performance Dashboard tool uses the same metric
gathering infrastructure as Nagios. If Performance
Dashboard is not working, check to see if Nagios is
successfully collecting data. If it is not, see
“Nagios
Troubleshooting” (page 235) .
• Use the following command to verify the
infrastructure:
/opt/hptc/supermon/usr/bin/get_stats -n
CMS_IP_ADDR
Where CMS_IP_ADDR is the IP address of the CMS
• Determine if there is any error output by running the
following command and interpreting its output:
# watch "ls -ltr /opt/hptc/cmu/tmp/GUI"
This command displays the following:
— a file named ReadSequence
— a series of log files named
number-ClusterResults.log
— a file named Sequence
Verify that these files are listed in this order and that
the numbers in the file names of the log files are
sequential.
• Run the following command to determine if the
infrastructure is gathering data:
/opt/hptc/cmu/bin/cmumon –actionfile \
/opt/hptc/cmu/etc/sysconfig/ActionAndAlertsFile.txt
–cmustatdir \
/opt/hptc/cmu/tmp/GUI --foreground --lm
NOTE: This command is continued over three lines
for clarity.
Performance Dashboard initiates without data. It
displays all dark gray.
Examine the two Performance Dashboard log files for
errors:
/var/opt/mx/logs/mxdomainmgr.0.log
/tmp/dbg
Performance Dashboard stops presenting data. The
broken GIF symbol is displayed.
Determine that JavaScript has permission to replace
context menus in the browser. Incorrect Performance Dashboard context menu is
displayed for a right-click of the mouse.
