Using Topology to Monitor the Cluster

The Topology view helps you monitor your cluster and identify problems. You can quickly view relationships between objects and see which resource groups and resource belong to each node.

How to Use Topology to Monitor and Update Your Cluster

To get to the Topology page, log into Oracle Solaris Cluster Manager, click Resource Groups, and click the Topology tab. Lines represent dependency and colocation relationships.

The online help provides detailed instructions on the elements of the view, as well as how to select an object for filtering the view, and right-clicking to see a context menu of actions for that object. You can collapse or restore the online help by clicking the arrow next to it. You can also collapse or restore the Filter.

The following table provides a list of the controls on the Resource Topology page.
