Generic JSON API

Monitor any JSON API in Checkmk — without writing a line of code.

Point it at a /health, /status, or metrics endpoint, pick the fields you care about, and get a Checkmk service for each — thresholds, graphs, and alerts included. One rule. Any API. Done.

What you get

• 🎯 Any endpoint, unmodified — Spring Boot, Kubernetes, vendor appliances, your own apps. No special response format required.
• 🧭 Pick fields by path — components.db.status, items[0].count, done.
• 🔁 Auto-discover arrays — nodes[*].status becomes one service per node, automatically.
• 📈 Thresholds & graphs in Checkmk — WARN/CRIT and metrics live in your rule, not upstream in the API.
• 🔐 Secure by default — basic or bearer auth via the password store, TLS verification on.
• 🧰 Bonus field picker — paste your JSON in the bundled explorer, click what to monitor, copy the ready-made rule.

In 30 seconds

GET /actuator/health → {"status": "UP", "components": {"db": {"status": "UP"}}}

Tick status (expect UP) and components.db.status → instant services JSON Health and JSON Database. That's the whole setup.
