VaniaMetricsPrometheus metrics for Minecraft servers and proxies

A small core serves /metrics; add one collector per plugin you run. Every platform it claims is tested on a real server.

No runtime dependencies

The core runs on the JDK alone, nothing shaded, nothing relocated. It writes the Prometheus text format itself.

Install only the collectors for the plugins you run. A missing target plugin disables its collector, never the core.

Per-player series are capped, and rare values are folded away rather than exploding your TSDB.

Paper, Purpur, Folia, Spigot, Sponge, Velocity, BungeeCord and Geyser, each started in a container by CI.
