# 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 only works on forge servers, it only executes `forge tps` to get tps and tick time informations
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
```
The RCON Module is only enabled if `RCON_HOST` and `RCON_PASSWORD` is set
# Usage
```
docker run -e RCON_HOST=127.0.0.1 \
-e RCON_PORT=25575 \
-e RCON_PASSWORD="Password" \
-p 8000:8000 \
-v /opt/all_the_mods_3/world:/world \
joshi425/minecraft_exporter
```
# Metrics
```
blocks_mined
blocks_picked_up
player_deaths
player_jumps
cm_traveled

player_health
player_score
entities_killed
damage_taken
damage_dealt
blocks_crafted
player_playtime

```
the following Metrics are only exported if RCON is configured:
```
