Not sure if this went through the 1st time...
For those of you who need to monitor your RedHat Clusters. I created a
new Check command that works under Zenoss or Nagios, that will monitor
your cluster through snmp.
You will need pysnmp and pyasn1 python modules for this command to work,
but I felt it was better then using a check by ssh command..
Here is the link if you want to try it out...
http://www.linuxdynasty.org/howto-monitor-redhat-cluster-using-snmp-and-python.html
I also created the equivalent of a clustat command using python and
snmp, so you do not have to be logged into a node in the cluster to run
it...
Code:
[r...@gfs1 python]# python rh_cluster_check.py -d gfs3 -c public -t cluster
WARNING, MyCluster is Quorate and Some services not running
[r...@gfs1 python]# python rh_cluster_check.py -d gfs1 -c public -t
service -s CIM
OK, CIM is running on gfs1
[r...@gfs1 python]# python rh_cluster_check.py -d gfs1 -c public -t node
-n "gfs3"
OK, gfs3 is Participating in cluster
clustat_snmp.py -d gfs1 -c public
