This MKP adds Minecraft monitoring to Checkmk. It includes an agent plugin that collects JSON data from the server and a check plugin that discovers services. Standard data such as players, MOTD, version, and ping is gathered via the server query interface, which is enabled by default on most servers. RCON is optional and only used for per-world performance metrics like TPS and tick times. At the moment only NeoForge is supported and tested; if you need other implementations or encounter problems, please open an issue. Error handling uses a fail counter to suppress short outages, and metrics are available for graphing and performance analysis.
