# Minecraft Input Plugin

The `minecraft` plugin connects to a Minecraft server using the RCON protocol
to collects scores from the server [scoreboard][].

This plugin is known to support Minecraft Java Edition versions 1.11 - 1.14.
When using an version of Minecraft earlier than 1.13, be aware that the values
for some criterion has changed and may need to be modified.

## Server Setup

Enable [RCON][] on the Minecraft server, add this to your server configuration
in the [server.properties][] file:

```conf
enable-rcon=true
rcon.password=<your password>
rcon.port=<1-65535>
```

Scoreboard [Objectives][] must be added using the server console for the
plugin to collect.  These can be added in game by players with op status,
from the server console, or over an RCON connection.

When getting started pick an easy to test objective.  This command will add an
objective that counts the number of times a player has jumped:

```sh
/scoreboard objectives add jumps minecraft.custom:minecraft.jump
```

Once a player has triggered the event they will be added to the scoreboard,
you can then list all players with recorded scores:

```sh
/scoreboard players list
```

View the current scores with a command, substituting your player name:

```sh
/scoreboard players list Etho
```

## Configuration

```toml @sample.conf
# Collects scores from a Minecraft server's scoreboard using the RCON protocol
[[inputs.minecraft]]
  ## Address of the Minecraft server.
  # server = "localhost"

  ## Server RCON Port.
  # port = "25575"

  ## Server RCON Password.
  password = ""

  ## Uncomment to remove deprecated metric components.
  # tagdrop = ["server"]
```

## Metrics

- minecraft
  - tags:
    - player
    - port (port of the server)
    - server (hostname:port, deprecated in 1.11; use `source` and `port` tags)
    - source (hostname of the server)
  - fields:
    - `<objective_name>` (integer, count)

## Sample Queries

Get the number of jumps per player in the last hour:

```sql
SELECT SPREAD("jumps") FROM "minecraft" WHERE time > now() - 1h GROUP BY "player"
```

## Example Output

```shell
minecraft,player=notch,source=127.0.0.1,port=25575 jumps=178i 1498261397000000000
minecraft,player=dinnerbone,source=127.0.0.1,port=25575 deaths=1i,jumps=1999i,cow_kills=1i 1498261397000000000
