• 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:

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.

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
