A dead-simple service that notifies you when something goes down.

Overview

Totmannschalter

Totmannschalter (German for dead man's switch) is a simple service that notifies you when it has not received any message from a service for a period of time. It is provided free to use by the German health insurance BKK VBU.

Usage

Currently, only Slack integration is supported.

  1. Create a Slack webhook: https://api.slack.com/messaging/webhooks. It's important to use one dedicated webhook per Prometheus instance, as the webhook is used to keep track of which services have not sent a request recently. The webhook will have a format like https://hooks.slack.com/services/Tttttttt/Bbbbbbb/Xxxxxxxxx
  2. Regularly send a HTTP POST request to https://totmannschalter.com/slack/Tttttttt/Bbbbbbb/Xxxxxxxxx using the last three parts of the webhook from step 1. The request body is ignored.
  3. If no request was received for 5 minutes, Totmannschalter will send a one-time message via the Slack webhook like this: Screenshot

Prometheus / Alertmanager integration

If you are using Prometheus and Alertmanager, you can use Totmannschalter like the following.

Add a PrometheusRule:

apiVersion: monitoring.coreos.com/v1
kind: PrometheusRule
metadata:
  name: totmannschalter
spec:
  groups:
    - name: Watchdog
      rules:
        - alert: Watchdog
          expr: vector(1)
          labels:
            notification: totmannschalter

Add to alertmanager.yaml:

route:
  routes:
    - match:
        notification: totmannschalter
      receiver: totmannschalter
      repeat_interval: 2m
receivers:
  - name: totmannschalter
    webhook_configs:
      - url: "https://totmannschalter.com/slack/Tttttttt/Bbbbbbb/Xxxxxxxxx"
