Starting Novemeber 7, we have been receiving high CPU usage alerts from two of the ESX hosts in our 3 host high availability cluster. We have been receiving more and more alerts each day starting with one and up to 5 alerts yesterday, the 12th.
When I check the performance history over the last 7 days of the hosts throwing the errors, the CPU usage never gets above 60%, let alone the 90% threshold for our usage errors.
Can anyone tell me what is causing these errors and why the performance history doesn't reflect the same statistics?
Thanks
