Hi,
that’s a very strange behaviour: When selecting “No agent” that you get an error message.
Have you:
- Installed the new relese of cmk?
- Created a new site with omd create …?
- Added a new host: WATO -> Hosts -> New Host > … DataSources: No Agent?
How have you done the migration? e.g. update 1.2.4 to 1.2.6 to 1.2.8 to 1.4 to 1.5 to 1.6?
