The Administration Console can be used to monitor the status of servers and clusters. Choose the Servers node in the left pane to view a list of servers and their status. To monitor a cluster, choose the cluster in the left pane and navigate to the Monitoring tab. This will display all of the servers that are configured for the cluster, and whether they are participating in the cluster. The Deployments tab, available on any cluster, is useful for determining which applications, EJB modules, web modules, or connectors have been deployed to that cluster.
