alertmanager-discord

This is a webserver that accepts webhooks from AlertManager. It will post your Prometheus alert notifications into a Discord channel as they trigger:

Warning

This program is not a replacement to alertmanager, it accepts webhooks from alertmanager, not Prometheus.

The standard "dataflow" should be:

Prometheus -------------> alertmanager -------------------> alertmanager-discord

alerting:                 receivers:
  alertmanagers:          - name: 'discord_webhook'         environment:
  - static_configs:         webhook_configs:                   - DISCORD_WEBHOOK=https://discordapp.com/api/we...
    - targets:              - url: 'http://localhost:9094'
       - 127.0.0.1:9093
