Destinations

Where alerts arrive: an email address, a Discord or Slack channel, your own webhook, or the iPhone app. A destination sends nothing until a rule points at it.

A destination is a place alerts can go. On its own it sends nothing: a rule decides which changes go there.

Add one

  1. Open Alerts and choose Destination.
  2. Pick the kind and fill in the address, channel webhook or URL. See Discord and Slack for where to find those.
  3. Choose Test to send a test message. If it does not arrive, the window tells you what the destination answered.
  4. Add a rule that points at it.

When delivery fails

A failed alert is tried again after 1 minute, 5 minutes, 30 minutes, 2 hours and 6 hours. After 20 failures in a row the destination is switched off and marked Disabled, so a dead channel does not fill your history. Fix the address and switch it on again.
