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](#compatibility).

“Agent-based Docker Monitoring” has been rewritten. No installation via pip is required. Bug fixes and additional graphs have been added. **Some graph labels are incompatible and are no longer updated.**

Checkmk agent for Alpine Linux as a signed apk (OpenRC service, apk update and OpenRC service checks, optional Docker/logwatch/Vaultwarden/AdGuard plugins) plus an MKP to enable agent plugins per host via a Setup rule - no Agent Bakery needed. Signed apk repository: [https://checkmk-alpine-agent-6f009d.gitlab.io](https://checkmk-alpine-agent-6f009d.gitlab.io) See [https://gitlab.com/checkmk1/checkmk\_alpine\_agent/](https://gitlab.com/checkmk1/checkmk_alpine_agent/) for the installation steps.

Checkmk extension for pending system/package updates on Linux (apt, dnf/yum, zypper, apk) and Windows (Windows Update, winget): security vs. normal updates, update cache age, reboot required and service restart needed - language-independent, never triggers repository rate limiting. Live-tested on 23 Linux distribution versions and Windows 11 / Server 2016 / 2022.
