I’ve got GitLab 10.5.6. I’d like to use Health Check information in my monitoring system. I can configure it by using Health Check endpoints with health check access token, but as this solution is depracated, I want to use IP whitelist. And I have some problems with it.
According to this article IP whitelist | GitLab I edited /etc/gitlab/gitlab.rb and added this line (as this GitLab was installed around version 7 or even older I think):
gitlab_rails[‘monitoring_whitelist’] = [‘127.0.0.0/8’, ‘192.168.0.1’, ‘X.X.X.X’, ‘Y.Y.Y.Y’]
where X.X.X.X is IP of my computer and Y.Y.Y.Y is IP of server with GitLab. After it I executed reconfiguration (gitlab-ctl reconfigure). And started tests… Below logs are from production.log file.
Execution of curl http://127.0.0.1:8888/-/readiness on server Y.Y.Y.Y returns proper JSON with expected data:

I don’t have any idea what I can check more. Maybe there’s lack of any more configuration in /etc/gitlab/gitlab.rb as it’s quite old GitLab instance.
I will appreciate any help.
