I'm new to using perfmon but need to know how to use it correctly because I suspect that the disks storing my Virtual Machine's on my Hyper-v Server are not good enough.
I ran perfmon on my Windows 7 machine to test it but I don't fully understand scaling on the line chart itself. I've attached a screenshot. Okay stupid question is the virtual line on the left hand side of the graph going from 0 to 100 represent percentages or second's or what? I know I'm supposed to use counters Avg.Disk sec/Read and Avg.Disk sec/Write to measure disk performance but first I need to understand the graph and what the 0 to 100 represents!
