Minecraft Prometheus Exporter

A Sponge plugin which exports Minecraft server stats for Prometheus.

Quick Start

Drop the the plugin jar into your servers mods directory and start your server.

After startup, the Prometheus metrics endpoint should be available at localhost:9225/metrics (assuming localhost is the server hostname).

The metrics port can be customized in the plugin's config file (a default config will be created after the first use).

Prometheus config

Add the following job to the scrape_configs section of your Prometheus configuration:

Single Server

- job_name: 'minecraft'
  static_configs:
    - targets: ['localhost:9225']

Multiple Server

  - job_name: 'minecraft'
    static_configs:
      - targets: ['localhost:9225']
        labels:
          group: 'server1'
      - targets: ['localhost:9226']
        labels:
          group: 'server2'
      - targets: ['localhost:9226']
        labels:
          group: 'server3'

In the grafana json add {group="serverX"} to each search query.

Import Grafana Dashboard

1. Navigate to Grafana -> Dashboards -> Import
2. Paste in or upload minecraft-grafana.json
3. Update "JVM Memory Used" to reflect your server max memory (Default 8G)
4. Edit (bottom right widget) -> Options -> Gauage -> Max
