Hello,
I am just forwarding the reply that I got from VC team:
==========================================================
I would suggest we first verify if we are seeing any other metric counters (e.g CPU usage) being collected successfully into the VC DB by looking at the past day performance chart under the Advanced->Performance in VI client and take a look at the host where this VM is residing on. If there are stats available, then that means VC has successfully collected stats from this ESX host. And the query result is only indicating the specific disk related metric counters is not available.
Is the past data data not available across multiple ESX hosts or only on certain specific ESX host? Based on the outcome, we can then determine what else we should collect to further troubleshoot this issue.
