Query cluster state using scripting

We can query cluster states using the wsadmin tool and scripting.

Perform the following steps to query cluster state:

Tasks

1. Identify the Cluster MBean and assign it to the cluster variable.
   • Jacl:

     set cluster [$AdminControl completeObjectName cell=mycell,type=Cluster,name=cluster1,*]
     

   • Jython:

     cluster = AdminControl.completeObjectName('cell=mycell,type=Cluster,name=cluster1,*')
     print cluster
     

   This command returns the Cluster MBean.

   Example output:

   WebSphere:cell=mycell,name=cluster1,mbeanIdentifier=Cluster,type=Cluster,process=cluster1
   

2. Query the cluster state.
   • Jacl:

     $AdminControl getAttribute $cluster state
     

   • Jython:

     AdminControl.getAttribute(cluster, 'state')
     

   This command returns the value of the run-time state attribute.
