Clusters view

The Clusters view is a tree view. It lists the clusters that exist in your environment and shows their state.

Selecting the All Clusters node displays overall resource utilization for all clusters in your integrated system and the elements that consume the highest amount of system resources in the Summary - All Clusters view on the right. Similarly, selecting a cluster node shows cluster-specific metrics in the Cluster Summary view on the right.
