Cluster Utilization shows the capacity of various resources over a specified period of time, to help administrators understand the scale and frequency of high resource consumption, including information about:
- CPU time
- Memory allocation

You can view a graphical representation of available resources in the Topology view of the web console Developer perspective.
If a resource has a message about resource limitations or quotas being reached, a yellow border appears around the resource name. Click the resource to open a side panel to see the message. If the Topology view has been zoomed out, a yellow dot indicates that a message is available.
If you are using List View from the View Shortcuts menu, resources appear as a list. The Alerts column indicates if a message is available.
