You can use the vSAN VM performance charts to monitor the workload on your virtual machines and virtual disks.

Before you begin

The vSAN performance service must be turned on before you can view performance charts.

About this task

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.

Note:

The performance service supports only virtual SCSI controllers for virtual disks. Virtual disks using other controllers, such as IDE, are not supported.

Procedure

  1. Navigate to the vSAN cluster in the vSphere Web Client Navigator, and select a VM.
  2. Click the Monitor tab and click Performance.
  3. Select vSAN - Virtual Machine Consumption. Select a time range for your query.

    vSAN displays performance charts for the VM, including IOPS, throughput, and latency.

  4. Select vSAN - Virtual Disk. Select a time range for your query.

    vSAN displays performance charts for the virtual disks, including IOPS, delayed normalized IOPS, virtual SCSI IOPS, virtual SCSI throughput, and virtual SCSI latency.
