Why are few database metrics in Database tab showing empty values in MS SQL monitor?
Before Applications Manager version 13910, We were showing high-level metrics for MS SQL monitor's Database usage from SQL server performance counters.
But from Applications Manager version 13910, We are showing detailed usage of Data files & Log files(Database Disk Utilization), VLF Details, DBCC Information, Mirroring Details which requires connection with each database present in the SQL server with db_datareader permission.

In case the SQL user used for monitoring doesn't have the mentioned permission either to connect to the respective database or execute the data collection query then the particular database metrics will be shown as empty in Database page.
This issue will be solved by giving proper permission on each database
