“clustat ( which is installed by the rgmanager rpm )
The clustat command will give you a quick status about all the
nodes in the cluster and of the services running. cman_tool ( which
is installed by the cman rpm ) The cman_tool command is for
managing a node in the cluster ( leaving, joining, votes, and
status ).“As you noticed above, the information you get from both
commands are extremely useful. The issue is that if you want the
information from clustat or cman_tool, you will have to run those
commands on a node that is part of the cluster. The reason this is
an issue to me, is because I do not want to be burdened with sshing
into one of the nodes anytime I want to know the status of the
cluster. I want to be able to get that info directly from my
desktop or from my monitoring system. After some research I
discovered that there is a package called cluster-snmp that is part
fo the yum “Clustering” Group.”
