Hey Guys!
So I'm monitoring my ESXi 5.5 Host, as well as each server on the host.
All monitoring is from the last 60 days.
While reviewing my monitoring, I noticed that our DC1 Virtual Disk Latency has averaged 1.5ms Read, and 5.9ms Write. Not that bad.
However, when I check the latency on the Windows monitoring side, I'm seeing an average of 4.4ms Read, and 22.8ms Write. That is form the Logical Drive Performance counter. When looking at the Physical Disk counter, I'm seeing an average of 112.6ms Read, and 64ms Write.
So, I guess what it comes down to, is: What do I care about?
Why does the Virtual Disk Latency look fine in VMWare when the Disk Latency through WMI is out of whack? What should I care about?
I'm attaching some images showing what data I'm seeing.
