The Datastore Performance dashboard displays the datastores that have high latency and their corresponding trend line.

You can use the dashboard widgets in several ways.

  • Use the Select a Datastore widget to select the datastore for which you want to view performance details. You can use the filter to narrow your list based on several parameters. After you identify the datastore you want to view, select it. The dashboard is automatically populated with the relevant data.

  • Use the Current IOPS and Latency of the VMs in the selected Datastore widget to view the current IOPS and latency of the VMs in the selected datastore.

  • Use the Datastores with High Latency and Outstanding IOs widget to view those datastores with high latency and outstanding disk I/O trends. Ideally, your datastores must not have outstanding disk I/O.

  • Use the other widgets in the dashboard to view trends for the selected datastore regarding disk latency, outstanding disk I/O, IOPS, and throughput.

  • Use the Historical IOPS Trend for the selected VM widget and the Historical Latency Trend of the selected VM widget to view the historical trend of IOPS and latency for a VM in the selected datastore. From the Current IOPS and Latency of the VMs in the selected Datastore widget, select a VM to populate the historical trends.
