The IOPS dashboard is designed to let you have a quick look on the SIOC (aka Storage I/O Control) IOPS metric of your datastores. This dashboard is of course higly related to the IORM SexiBoard that provide latency metrics.
Like the datastore latency metric, having high IOPS activity could impact your storage performances.
This dashboard is actually a template and needs a bit of configuration. You first need to enable SIOC logging on your ESXi servers and then replace the storage vendors names by your datastore ones in the queries. Since this dashboard is meant to display datastore IOPS per storage controller/array, you can use paterns like
nas.netapp.* or any leading caracters you’re using to manage your datastores.
