Monitoring a server

The following example is provided in examples/mc-monitor-telegraf

Given the telegraf config file:

[[inputs.socket_listener]]
  service_address = "tcp://:8094"

[[outputs.file]]
  files = ["stdout"]

...and a Docker composition of telegraf and mc-monitor services:

version: '3'

services:
  telegraf:
    image: telegraf:1.13
    volumes:
    - ./telegraf.conf:/etc/telegraf/telegraf.conf:ro
  monitor:
    image: itzg/mc-monitor
    command: gather-for-telegraf
    environment:
      GATHER_INTERVAL: 10s
      GATHER_TELEGRAF_ADDRESS: telegraf:8094
      GATHER_SERVERS: mc.hypixel.net

The output of the telegraf service will show metric entries such as:
