I have a windows host that is behaving very slowly. All the counters (CPU, Disk, etc) appear to be normal.
The virtual host itself is ESX, and is on a VNX Cluster with 13GB free disk space on a 2 TB disk.
I am assuming that ESX doesn't like the low disk space on that LUN and as a result is having issues with all VMs resident on there.
Right now I'm VMotioning 120 GB off that LUN, and it will take some time. Is there any analysis I can do while my host is "acting slow"?
My goal is to identify a Windows (or VMWare) metric that will allow me to predict this performance degradation.
