Report still displays the old agent. (4323916)

For one of my cluster reports, it shows as 'There is no data to display'

I deleted my old agent, installed new agent on different server. But one of my old reports still shows up the old cluster which was part of old agent & displays as 'There's No Data to Display'

Check the services under dashboards | Service | Service builders.

Here expand the service you use for the report to see if you still see the old agent cluster object which hasn't been updated for long time.

If yes, delete the object thorugh Data Management Dashboard ( Dashboards | Management Server | Servers -> Data Management)

Expand All Services -> Categories(Expand the apporpiate service)

Delete the cluster old that's part of the old agent.

Then generate or run the report to see if that stopped showing the old cluster object in your reports.
