You can use the Virtual SAN VM performance charts to monitor the workload on your virtual machines and virtual disks.
When the performance service is turned on, you can view detailed statistical charts for virtual machine performance and virtual disk performance. VM performance statistics cannot be collected during migration between hosts, so you might notice a gap of several minutes in the VM performance chart.
The performance service supports only virtual SCSI controllers for virtual disks. Virtual disks using other controllers, such as IDE, are not supported.
The Virtual SAN performance service must be turned on before you can view performance charts.
- Navigate to the Virtual SAN cluster in the vSphere Web Client Navigator, and select a VM.
- 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 the VM, including IOPS, throughput, and latency.
- Select Virtual SAN - Virtual Disk. Select a time range for your query.
Virtual SAN displays performance charts for the virtual disks, including IOPS, delayed normalized IOPS, virtual SCSI IOPS, virtual SCSI throughput, and virtual SCSI latency.
