VM Monitoring
In the vSphere interface menu, go to the Hosts and Clusters dashboard.
Navigate to your VM and select it.
The Monitor tab presents performance Overview.
You may see real-time metrics or choose to check a timeframe to see performance evolution.
You may also change the view to dig on more specific subjects.
You may also use the Utilization section to help your investigations.
Cluster monitoring
In the vSphere interface menu, go to the Hosts and Clusters dashboard.
Navigate to your Cluster and select it.
The Monitor tab presents performance Overview.
You may see real-time metrics or choose to check a timeframe to see performance evolution.
