Examining Performance in a Virtual SAN Cluster

Monitor the performance of virtual machines, hosts, and the Virtual SAN datastore to identify potential storage problems.

Monitor regularly the following performance indicators to identify faults in Virtual SAN storage, for example, by using the performance charts in the vSphere Web Client:

• Datastore. Rate of I/O operations on the aggregated datastore.
• Virtual Machine. I/O operations, memory and CPU usage, network throughput and bandwidth.

You can use the Virtual SAN performance service to access detailed performance charts. For information about using the performance service, see Monitoring Virtual SAN Performance. For more information about using performance data in a Virtual SAN cluster, see the Virtual SAN Troubleshooting Reference Manual.
