I have been requested by our CIO to gather information regarding our cluster. We have currently have 5 servers and 181 VM's running across them, but we are starting to run low on memory.
Is there anyway to generate a usage report to see which VM's are rarely or, if ever, used? I know you can look at each VM, but I would like a "totals" type of report if possible. I can then justify shutting some of them down as they are never used and are just consuming resources.
We are running ESXi 6.0.0
Sonarhub, provide a free reporting tool that might give you what you are looking for.
There are also some community led script resources that might work depending on what you need and your comfort in running scripts..
Lots of tools out there offering free trials, such vRealize Operations Manager, VMTurbo Operations Manager, Veeam ONE.
I'm more curious how you define "rarely used". Are you interested in memory/CPU utilisation or any other metrics you would like to look at?
