2.7.1 Monitoring during failover in the SQL Server AlwaysOn Availability Group configuration
When PFM - Agent for Microsoft SQL Server collects information for the instances of the Microsoft SQL Server that has databases in the SQL Server AlwaysOn Availability Group configuration, if a failover occurs, PFM - Agent for Microsoft SQL Server does not collect information (at the time the failover occurs) for the instances of each database.
Also, the KAVF219812-E message is output to the agent log. However, there are no operational problems.
