Mineflux is a Telegraf plugin that collects data from Minecraft servers and writes it into InfluxDB, allowing for visualization in Chronograf. The plugin uses the RCON protocol to gather data from the server's scoreboard, which tracks player achievements such as kills, deaths, and jumps. To set up the plugin, users need to install InfluxDB, Telegraf, and Chronograf, configure the Telegraf service with Minecraft plugin options, and start the Telegraf service with the plugin enabled. The plugin provides a minimal interface that is easy to build around, making it simple for users to collect data from their own Minecraft servers and visualize it in Chronograf.
