Title
Disk Latency and Slowest Disk data are missing from the Overview dashboard -
Description
Slowest disk metrics were missing from the global DB dashboard for all the sql servers which are running on the VM's. For the physical sql servers they are displayed fine. Normally when we click on the host name from the DB dashboard it takes us to the IC dashboard but in this case it is redirected to the vmware dashboard.
-
Cause
Disk monitoring was not enabled in the WindowsAgent
-
Resolution
Set the Please agent status property (ASP) value for the associated WindowsAgent and enable the "Collect disk metrics" configuration to be set to true.

Additional Information
As per R&D investigation, the "monitoredHost" is being used to gather disk information; as this is a cluster the Cluster Virtual Name is used, but there is no IC agent for it (expected behavior). The "active_host" needs to be taken into consideration when getting disk information.
