A super simple script to monitor a self hosted GitLab (https://about.gitlab.com/) server.

===== Installation =====
=== Client side ===
Change the appropriate vars in the script (see below) and place in /usr/lib/xymon/client/ext (or wherever you have the client extension dir).

Vars:
  * _SOME_IP_ - The Xymon server IP
  * _SOME_HOSTNAME_ - The Xymon server hostname/URL
  * _GITLAB_URL_ - Gitlab instance URL
  * _GITLAB_TOKEN_ - The Gitlab healthcheck token that you can get from _GITLAB_URL_/admin/health_check

Add the following to clientlaunch.cfg

        [gitlab]
        ENVFILE $XYMONCLIENTHOME/etc/xymonclient.cfg
        CMD $XYMONCLIENTHOME/ext/gitlab.pl
        LOGFILE $XYMONCLIENTHOME/logs/gitlab.log
        INTERVAL 5m
