We're currently experiencing several disk latency alarms since upgrading to vCenter 5.0. It only seems to be for a short period of time in the day. Was the alarm threshold changed in vCenter 5?
What'd be the recommended way to punch down to find out what is causing the issue?
I would try esxtop
here are some useful links detailing its usage and how to interpret the counters etc...
Much appreciated. However in order to use esxtop I need to SSH into a host correct? I'd like to see the VM statistics per datastore, as it only seems to be a select few datastores. Just trying to narrow down the culprit. I'll try to use esxtop for each of our hosts during the spike to see if I can see anything. Thanks again!
