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).

A guided setup wizard for the Generic JSON API agent — build a monitoring rule from your API's real response, right inside Checkmk. This is the optional companion to the **Generic JSON API** package. It adds an in-site wizard under **Setup → Quick setup** that walks you from a live API response to a finished rule — no `rules.mk`, no `curl`, no leaving Checkmk. ## Requires - The **Generic JSON API** (`json_api`) package must be installed and enabled first — this Explorer only *builds* rules for that agent; it does not monitor anything on its own. - **Checkmk 2.5 or newer**, any edition. The wizard is built on Checkmk's native Quick-Setup UI, which does not exist on 2.4. ## What it does - 🧭 **Guided, step by step** — choose the target folder and host, define one or more endpoints (URL, method, auth, headers, TLS/redirect options), then pick the fields to monitor. - 🔎 **Fetches the real response** — the wizard calls each endpoint from the site and shows you the actual JSON, so you click the fields that exist instead of guessing paths. - 🎯 **Point-and-pick fields** — select values by path, set WARN/CRIT thresholds, units, a numeric transform, element counting, or string matching — the same options the agent supports. - ✅ **Live preview before you commit** — the review step evaluates every chosen field against the fetched sample and shows the resulting service state, so you catch a wrong path or threshold before the rule exists. - 🔐 **Secure by default** — credentials are stored in the Checkmk password store and referenced, never written in clear text; TLS verification stays on. - 🚀 **One click to create** — the wizard writes the finished Generic JSON API rule for you. ## In short Install the **Generic JSON API** agent, then install this Explorer. Open **Setup → Quick setup → Generic JSON API**, point it at an endpoint, tick the fields you care about, and press create. The services appear on your host. ## Details - Extra/companion package — install alongside, and after, the Generic JSON API agent. - Checkmk **2.5+**, any edition. - Install via `mkp add` / `mkp enable`, or **Setup → Extension packages**. - GPL-2.0-only.
