A Checkmk special agent plus check plugins to monitor GitLab through its
REST API (v4) — both self-hosted (CE/EE) and GitLab.com (SaaS) — built in
the style of the bundled Jenkins special agent. Tested layout for Checkmk
2.5.0, GitLab EE 19.x, and tested successfully against
a GitLab.com free account. Some services are admin- or EE-only and therefore
self-hosted only — see Compatibility.
