CPU Wait?

[Jcooper12]

There doesn't seem to be much information out there about what a decent CPU wait time is. My VMs are constantly around 20,000ms cpu wait time. Does anyone have experience with this? I know that it is the time that it has to wait for a datastore operation, but our VMs seem to running alright at 20,000 ms with the occassional user complaints.

In general you should only have to worry about %RDY and %CSTP. Just from memory a lot of states are included into the WAIT counter and does not typically indicate any error.

I would not generally look at WAIT but it can highlight an issue.

WAIT is the amount of time a virtual is waiting for something, this can be from the guest side of the host side, could be waiting on IO operations or could just be idle.

If you grab you WAIT then minus IDLE and your left with nothing or a low number then its all good and your machines a just idle.

WAIT - IDLE = time a virtual machine is spent waiting for IO
