CMK version: 2.2.0p32
OS version: Ubuntu 20.04

Error message: Could not read API response, make sure the URL you provided is correct.

Hello,

I just updated my CheckMK instance to version 2.2.0p32 which is running fine so far.

Besides that I also updated Grafana to the newest version (11.1.3) and tried to use the newest CheckMK plugin (3.3.0) in Grafana. But I can’t connect the plugin to the site. I always get the error Could not read API response, make sure the URL you provided is correct.

The URL looks like this: https://CHECKMK.MYDOMAIN.COM/MYSITE
Also the URL is correct. I already tried it via curl command directly from the Grafana host.

Web developer tools in Edge shows me the following URL is called and the return code is 410:
https://MYGRAFANA:3000/api/datasources/proxy/uid/SOMESORTOFID/cmk/check_mk/webapi.py?action=get_combined_graph_identifications

If I understand this URL correctly it tries to connect to a webapi URL to CheckMK but as far as I know there is no Webapi anymore in this version of CheckMK. Shouldn’t be the Rest API be called?

I also can’t set any version in the plugin like mentioned in the CheckMK guide Integrating Checkmk in Grafana at point 4 picture 3.

Did you download it from Github or Grafana? The Grafana version only works with Checkmk cloud or MSP.

Directly from Github.
This version: Release v3.3.0 · Checkmk/grafana-checkmk-datasource · GitHub

This Zip file:
tribe-29-checkmk-datasource-3.3.0.zip

Looks like the problem is Grafana itself. After reinstalling an older version of Grafana (9.5.21) everything works as expected. Maybe a newer versions work too.

So for the moment I use:
Grafana 9.5.21
Grafana CheckMK Plugin 3.3.0
CheckMK Enterprise 2.2.0p32

If you think this might be an issue with our Grafana integration, you can also open an issue on Github.

If you can not set the edition or version @Anders tip with the signed plugin is spot on.

This means, that you are specifying version < 2.2 in the version dropdown in the Checkmk Grafana plugin, but you are using a Checkmk version (>= 2.2) that removed the webapi, so it returns a 410 Gone

Have you checked if you maybe have two Checkmk data sources in Grafana?
