Thanks Mark,
I create a new role (copy of read only) for the collector and added
Storage Views > View and now I am seeing the storage metrics you mentioned.
- The user account you use for collecting data with vCenter Operations Manager determines the scope and accuracy of the monitoring data.
- vCenter Operations Manager does not require administrator privileges to collect data from a vCenter Server. However, the scope of data collected depends on the privileges of the user you assign as the Collection user on the vCenter Operations Manager Administration portal. The minimum privileges required to collect data are Global: Health and Storage Views: View.
- vCenter Operations Manager calculates metric values based only on visibility the Collection user has to the inventory. If certain objects are not visible, the values for these objects are not taken into account when calculating metrics for their container objects.
