We are using Always On Availability group and Servers are monitored using IDERA SQL DM. Here issue is: [SQLdmRepository].[dbo].[DatabaseStatistics] table is not collecting data for these Availability group servers/databases. why? while data is there for other non Always On Availability group Databases on other servers.
I cannot tell you why it is not collecting data in your case, but in our installation, the AG-DBs have entries in the DatabaseStatistics table. So I can confirm your assumption, that there should be data for AG-DBs in that table.I suggest to open a case with idera support.
Thank you Daniel. I have already working on opening ticket with IDERA.
