VMware Storage IO This dashboard has 2 template variables - vCenter and Cluster.. This allows you to select the vCenter you want and filter on the Clusters to show in the dashboard.. It was built on Grafana 3.0 and will work also with 4.2. The collector used was vsphere-influxdb-go (https://github.com/Oxalide/vsphere-influxdb-go)..
The dashboard gives you a list of all VMs within the particular cluster and which ones are the top offenders for IO.
