Our solution with Grid Engine is to have a cron job monitoring the
contents of the IPMI SEL. If any messages are in the SEL that are not on
a whitelist, a file in /var gets generated (conversely, if no messages
are in the SEL, the file gets removed). We have a GE load sensor that
monitors for the presence of this file and places that node in an alarm
state when it sees this file, preventing new jobs from being scheduled
on the node. We then have Nagios monitoring the output of "qstat -xml"
on the scheduler nodes so we get notified of when a node goes into an
alarm state.
