Only the past 23 hours of SQL PI data is visble for a SQL Server database agent.
说明
Only the past 23 hours of SQL PI data is visble for a SQL Server database agent.
原因
User changed the host name and instance name of the monitored host in the Agent Status Property to an incorrect value so that the agent referred to a new PI_Instance key. The old data with the old instance_key could not be retrieved by the FMS.
解决办法
Disable and re enable the PI extension for the database agent
