Actual underutilized VMs interms of CPU/Mem #335

Open danilansible opened 1 year ago

danilansible commented 1 year ago

Hi again,

I came across an usecase where team needs to find underutilized VMs over the time interms of cpu/memory usage on ACTUALS so to identify and then reconfigure such VMs to make space for other VMs

What w beould the closest metric to get the actual guest mem usage as a whole?

Any guidance is much appreciated. Thanks

Memory usage is tricky... You could start with guest active memory since no activity would reflect oversized memory or underutilized vm. VROPS has a trick by reading through the vmtools... https://blogs.vmware.com/management/2019/01/enhancements-to-virtual-machine-memory-metrics-in-vrealize-operations.html
