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: [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 OK, CIM is running on gfs1 [root@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 Cluster Status for MyCluster @ Fri Aug 28 11:59:40 2009 Member Status: Quorate Total Nodes: 3 Total Votes: 5 Votes Needed For Quorum: 3 Member Name Status ------ ---- ------ gfs1 Participating in cluster gfs2 Participating in cluster gfs3 Participating in cluster Service Name Owner State Start Up Mode ------- ---- ----- ----- ------------- Pirahna stopped automatic CIM gfs1 running automatic |
