Monitoring the Cluster
You can monitor the cluster in the management center and at the threat defense CLI.
-
Cluster Status dialog box, which is available from the More (
) icon or from the page > General area >
Cluster Live Status link.Cluster Status 
The Control node has a graphic indicator identifying its role.
Cluster member Status includes the following states:
-
In Sync.—The node is registered with the management center.
-
Pending Registration—The node is part of the cluster, but has not yet registered with the management center. If a node fails to register, you can retry registration by clicking Reconcile All.
-
Clustering is disabled—The node is registered with the management center, but is an inactive member of the cluster. The clustering configuration remains intact if you intend to later re-enable it, or you can delete the node from the cluster.
-
Joining cluster...—The node is joining the cluster on the chassis, but has not completed joining. After it joins, it will register with the management center.
For each node, you can view the Summary or the History.
