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...
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...
[root gfs1 python]# python rh_cluster_check.py -d gfs3 -c public -t cluster
WARNING, MyCluster is Quorate and Some services not running
[root gfs1 python]# python rh_cluster_check.py -d gfs1 -c public -t service -s CIM

[root gfs1 python]# python rh_cluster_check.py -d gfs1 -c public -t node -n "gfs3"
