minecraft-exporter

This is a prometheus minecraft exporter

This exporter reads minecrafts nbt files, the advancements files and can optionally connect via RCON to your minecraft server.

To use it mount your world to /world in the container

RCON connection is used to get online Players
On Forge Servers enable FORGE_SERVER to get tps information
On Paper Servers enable PAPER_SERVER to get tps information

To enable rcon on your minecraft server add the following to the server.properties file:

broadcast-rcon-to-ops=false
rcon.port=25575
rcon.password=Password
enable-rcon=true

Note: Broadcast RCON to ops is disabled, to avoid ops receiving spam whilst ingame.
