The Cluster Performance dashboard allows you to identify which clusters have VMs that suffer from memory contention and CPU contention.
You can use the dashboard widgets in several ways.
Use the Clusters dashboard to select the cluster for which you want to view performance details. You can use the filter to narrow your list based on several parameters. After you identify the cluster you want to view, select it. The dashboard is automatically populated with the relevant data.
Use the Clusters Colored by Critical Alerts and Sized by Host Count widget to view only the critical alerts.
View the maximum and average CPU, memory disk, and disk latency for the VMs. If the VM faces contention, it might mean that the underlying infrastructure does not have enough resources to meet the needs of the VMs.
View a list of 10 VMs that face CPU, memory, and disk latency contention. You can then troubleshoot and take steps to resolve the problem.
