The Troubleshoot a Cluster dashboard allows you to identify which clusters have VMs that suffer from memory contention and CPU contention.

You can select a specific cluster you want to work with to view a quick summary of number of hosts participating in that cluster and the VMs being served by them. The dashboard provides you the current and past utilization trends and the known issues on the cluster as alerts.

You can view the hierarchy of objects related to the cluster and review the status to determine if the objects are impacted due to the current health of the cluster. You can quickly identify any contention issues by looking at the maximum and average contention faced by the virtual machines on the selected cluster. The dashboard also provides details of specific virtual machines that might be impacted by resource contention.

You can use the dashboard widgets in several ways.

Clusters: Use this widget 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.

Clusters Colored by Critical Alerts and Sized by Host Count: Use this 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.
