You can use the VMware Host Client to monitor the vSAN environment of your ESXi host.


vSAN service must be enabled in the vSphere Web Client before you can view the vSAN related screens for a datastore.


  1. Click Storage in the VMware Host Client inventory.
  2. On the Datastores tab, click vSAN Datastore.
    The vSAN Datastore expands in the VMware Host Client navigator.
  3. Click Monitor.
    You are present with the vSAN, Host, and Health tabs in the UI.
    Option Description
    vSAN Displays the configurations for the current host. You can edit the settings for the claiming mode and deduplication. You can also view the settings for:
    • Encryption – vSAN supports encryption of the information for the whole vSAN datastore.
    • ISCSI Service – Additional service through the iSCSI service.
    • Performance Service - Collects data on how the datastore works. For example, the speed of a read/write operation.
    Hosts Displays a list of all the hosts on the vSAN server with their IP and the fault domain they belong to.
    Health The Health tab contains tests organized in groups. You are present with the following groups:
    • Performance Service
    • Network
    • Physical disk
    • Data
    • Cluster
    • Limits

    Each group is labeled with a status icon for an error, warning, unknown or healthy. The status of the group represents the most severe state of the test belonging to that group. To view the tests and their descriptions, click the expand icon in the top right corner of the group of interest. From the expanded card you can review all the tests belonging to the group, the result of their execution and get more information about what each test examines on the system.

  4. Select the vSAN parameter that you want to monitor.
