Hi @dubdub
good to hear that this helped you.
You can mark the response as a solution to help others in the future.
I don’t think we need a locking mechanism there. Just create another admin user to work on your checkmk. I normally suggest to my customers to leave the cmkadmin untouched in case of an emergency and work with personalised users.
For the grafana problem you can follow the official documentation Integrating Checkmk in Grafana
If that is not helping you you can create another forum thread with more detailed information.
Regards
Norm
