I am using the "2.0.0p15.cee". I also have the same problem.... Could somebody give some comments for this problem?

But it works like below.

# curl 'cma03/remote_site/check_mk/view.py?_username=automation&_secret=XXXXXXXXXXX&view_name=svcproblems&output_format=json'; [ [ "service_state", "host", "service_description", "service_icons", "svc_plugin_output", "svc_state_age", "svc_check_age", "perfometer" ], [

Looks like you are trying to connect to a remote site in a distributed monitoring environment. According to the documentation, you have to connect to the central site.

See 2.2 on the following page: https://docs.checkmk.com/latest/en/grafana.html

Dear LevonTostig,

I disable the "Distributed Monitoring" then it was the same.

So I created the new site(mysite) but the problem was the same like attached file. If you had some idea kindly tell me.

Same issue here... Using 2.0.0p17 (CRE) - has anyone figured this out?

[CVT-Adam]

Was there ever a resolution to this problem? I am on CheckMK 2.1.0p17. I have been using the old grafana plugin of version 1.1.0 for a long time and it still works but I can't seem to upgrade to the new 2.0.3 version. I get the same error above.

[TheSpacyCat]

The problem here is that there are a lot of different conditions under which this error could occur. If you could share the response of the network request with me, I can take a look. It should show up as webapi.py?action=get_combined_graph_identifications in the Network Tab of the Inspector.

[m1schka]

for me the issue was an http proxy in between, which was sending a forbidden (to not use it for the connection to checkmk). I was able to see the error when switching from https to http (in the mentioned network inspector of the chrome developer tools).

so excluding it using NOPROXY was fixing it the error, revealing a second issue (visible thanks to the newest 2.0.3 plugin version). you must use an automation secret instead of a password.

hope this helps some of you

this below is from the grafana.log file when i attempt save and test in the datasource. @m1schka I am using the secret and not the password for the automation user already.

[m1schka]

this looks like grafana is not trusting the certificate from the checkmk I'm using the grafana operator inside k8s, there this can be achieved by mounting the certificates to /etc/ssl/certs/ca-certificates.crt using a configmap and extraVolume(Mounts). in case of openshift this configmap can easily been created by letting openshift injecting the cluster trusted CA into a configmap

I hope this helps

[CVT-Adam]

I find that strange because my checkmk is loaded with a valid wildcard ssl from godaddy.

[CVT-Adam]

Ok well sure enough I put the SSL into the ca-certificates.crt file and rebooted and now it is connecting and pulling data just fine. I do find that odd that I had to do that for a publicly validated certificate, but all is working now, and I am getting the host and data.

Hello All,

I also have the same problem. I am using the CheckMK "1.6.0p20" Enterprise and the Open Source Grafana v9.3.6 (978237e7cb)

For the plug-in, I´m using the "grafana-checkmk-datasource-1.1.0", because the compatibility with CheckMK "1.6.0p20", as I could see on https://docs.checkmk.com/1.6.0/en/grafana.html.

But, I not sure if this plug-in version 1.1.0 works fine with Open Source Grafana v9.3.6 (978237e7cb).

Checking on the README.md file zip on "https://github.com/tribe29/grafana-checkmk-datasource/archive/1.1.0.zip" I could check it below.

Requirements

Minimal Checkmk Version is 1.6.0p2. The Grafana datsource requires the Checkmk Enterprise Edition or Checkmk Managed Services Edition.

But, I couldn´t find information about Grafana requirements. How can I check compatibility between them?

And about the error message, someone could help me to understand it? I´m really newbie on this new world.

Thanks in advance.

Passive maintenance for checkmk 1.6.0 ended 2022-09-09 (see https://docs.checkmk.com/latest/en/cmk_versions.html#support_periods). We don't support this version for this plugin.

Version 1.1.0 of this plugin was release on 2019-09-30. Grafana released 6.3.6 on 2019-09-23, so those two versions probably should work together.

As for general troubleshooting you have multiple places to look for hints what's going wrong:

• network tab of the development console of your browser
• grafana logs
• checkmk logs

Please understand that we can not put time into supporting old versions of this plugin.

Hello @BenediktSeidl,

Sure, completely understand.

Thanks for the information.

I think all issues from this ticket should be resolved, so I'm closing that. If I missed something, please add a comment.
