How do I get alerted when an Airflow DAG fails on Astronomer?
WebRun checks Astronomer DAG runs every hour across your deployments. The moment one fails, it messages the on-call engineer on WhatsApp with the DAG, the task, and a link to the logs, and schedules a fix window on Google Calendar if the same DAG has failed more than once that week, so recurring breakage gets real time booked against it.
- Failed DAGs reach the on-call engineer within the hour
- Recurring failures get a scheduled fix window, not repeated pages
- Every alert links straight to the run logs, no manual searching

Questions, answered
Will it retry or fix the DAG on its own?
No. WebRun only reports the failure and schedules time to fix it. Retrying a task or editing the DAG is left to a human.
Why message on WhatsApp instead of just logging it?
A failed DAG is often time-sensitive, feeding a downstream report or model. A direct WhatsApp message gets it in front of the on-call engineer faster than a dashboard they'd have to check.
What counts as a recurring failure?
The same DAG failing more than once in the same week triggers a scheduled fix window, so a one-off blip doesn't clutter the owner's calendar.
