Help with Alias in graphs (screenshots to help) vmware datastores

Hello,

I’m trying to list all our datastores in VMware and show their capacity and what’s used. I’ve got close with this:

Imgur

However

  1. How can I show under the graph the name of the host and field? So “Capacity - Hostname”. At the moment it shows just the hostname, I need the field values to show as well in query A and B.
  2. Now the bigger picture I need to list all datastores and on a host in the dropdown list, at the moment I see all the datastores to select regardless to what host I select, is this possible?

Thanks
