$ ./check_sel --help
check_sel <--help> -H hostname <-t timeout>
--help
-H Host to check
--cache file Persistent cache to remember where we last read/processed
default /hptc_cluster/adm/logs/sel/cache/selcache-$nodename.db
--clear Clear the SEL log after reading
--clearifused n Clear the log only if it is past n% full
--ignoreunknownhosts
Ignore unknown hosts, default is to return critical
--last n Only log entries from the last n days, hours, or minutes
--logfile file Log output to file,

USE6371RA4 Enclosure Status - Warning> The enclosure is reporting one or more
warning conditions for environmental sensors gathered from the device.
Check the sensor status on the enclosure. Verify the status of the
Enclosures Collection Monitor which provides this data.
nh The Enclosure Collection
Monitor collects sensor information from the blade system enclosures.
Enclosure status can be found in the Nagios Enclosure Status service
plug-in status. A critical status indicates that one or more of the
monitored enclosures has either posted a critical status or the
plug-in has been unable to contact the enclosure. Verify logon
credentials are correct if sensor data is not available.
mercury nh neptune Nodes have crossed the load average warning
thresholds set in nagios_vars.ini. These are site specific values and
simply indicate resource usage above an expected range. Verify that the
node does not have a misbehaving job or some other problem causing it to
use more CPU then expected.
mercury neptune NodeInfo - Critical> Critical thresholds have been reached for max users,
processes, or zombies etc. See nagios_vars.ini for threshold values.
Values are site specific and critical values indicate values have been
exceeded.
