Change in the API latest version

Hi there,

been using this script check_gitlab.rb · master · Marco Peterseil / check_gitlab · GitLab last few years. So far so good, but with the latest update of Gitlab (CE) I have noticed that it cannot find the right API paths anymore.

How to solve and regain monitoring enabled again,
Thanks

Problem to solve

With the latest version of Gitlab the scripts shows Unknown - Not found,

root@behemoth.home.lan:~# /usr/lib/nagios/plugins/check_gitlab.rb -m health -s https://127.0.0.1 -k
Unknown - Not Found
root@behemoth.home.lan:~#

Probably some API paths are being removed from the configuration.

Steps to reproduce

Only seen in the latest version:

root@behemoth.home.lan:~# dpkg -l gitlab-ce
Desired=Unknown/Install/Remove/Purge/Hold
| Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend

Thanks

The source shows a CLI parameter --debug which could be helpful to see more details.

Did some research with Duo Agentic Chat on the GitLab source code and docs to verify the readiness endpoint is there and works.

Maybe the required allowlists are not configured anymore?
