12.10 LSF-HPC Monitoring
LSF-HPC i s monitored and controlled by N agio s using the check_lsf plug-in.
When LSF-HPC is down, the response of the check_l
sf plug-in depends on whether
LSF-HPC failo ver is enabled or disabled.
When L S F -HPC failover is disabled The check_lsf plug-in returns an imm ediate failure
notification to Nagios.
When LSF-HPC failover is enabled The check_lsf plug-in decides if LSF-HPC is
supposed to be running. If so, it acquires a list
of resou rce managem ent nodes and tries to restart
LSF-HPC on each of those nodes, in turn, until one
succeeds, or until the list is exhausted.
If successful, the check_lsf plug-in returns LSF OK
- restarted message.
If the restart procedure fails
,thecheck_lsf plug-in
returns a failur e notificatio
n.
The follo wing list s the Nagios
messages for LSF failover monitor status:

12.10.1 LSF Execution Host Failure

down is disp layed.
