Turn on Virtual SAN Performance Service

When you create a Virtual SAN cluster, the performance service is disabled. Turn on Virtual SAN performance service to monitor the performance of Virtual SAN clusters, hosts, disks, and VMs.

When you turn on the performance service, Virtual SAN places a Stats database object in the datastore to collect statistical data. The Stats database is a namespace object in the cluster's Virtual SAN datastore.

Prerequisites

• All hosts in the Virtual SAN cluster must be running ESXi 6.5 or later.
• Before you enable the Virtual SAN performance service, make sure that the cluster is properly configured and has no unresolved health problems.

Procedure

1. Navigate to the Virtual SAN cluster in the vSphere Web Client navigator.
2. Click the Configure tab.
3. Under Virtual SAN, select Health and Performance.
4. Click Edit to edit the performance service settings.
5. Select the Turn On Virtual SAN performance service check box.
   You can turn off the Virtual SAN performance service by deselecting the check box.
6. Select a storage policy for the Stats database object and click OK.
