You can use the Virtual SAN cluster performance charts to monitor the workload in your cluster and determine the root cause of problems.
When the performance service is turned on, the cluster summary displays an overview of Virtual SAN performance statistics, including Virtual SAN IOPS, throughput, and latency. At the cluster level, you can view detailed statistical charts for virtual machine consumption and the Virtual SAN back end.
Prerequisites
The Virtual SAN performance service must be turned on before you can view performance charts.
Procedure
- Navigate to the Virtual SAN cluster in the vSphere Web Client Navigator.
- Click the Monitor tab and click Performance.
- Select Virtual SAN - Virtual Machine Consumption. Select a time range for your query.
Virtual SAN displays performance charts for clients running on the cluster, including IOPS, throughput, latency, congestions, and outstanding I/Os. The statistics on these charts are aggregated from the hosts within the cluster.
- Select Virtual SAN - Backend. Select a time range for your query.
Virtual SAN displays performance charts for the cluster back-end operations, including IOPS, throughput, latency, congestions, and outstanding I/Os. The statistics on these charts are aggregated from the hosts within the cluster.
