I Replaced Our Entire On-Call Rotation With 4 Python Scripts

Описание и применение

Автоматизация ротации on‑call с помощью четырёх Python‑скриптов снизила ложные тревоги на 80 %, устранила выгорание команды и сэкономила 4 часа в неделю на администрировании инцидентов.

Задача

On‑call rotation caused burnout with 3 AM pages, false alarms, and no real sleep for staff.

Результат

Three incidents were handled automatically while staff slept, false‑alarm pages dropped 80 %, on‑call burnout was eliminated, and 4 hours per week were saved on incident administration.

Рабочий процесс

• 1. Receive alerts and run Script 1 to classify severity; page humans only for P0/P1 or queue others for morning review.
• 2. On deployment, run Script 2 to monitor error rates; if spike >3× baseline within 5 min, auto‑rollback and notify team.
• 3. After incident resolution, run Script 3 to collect timeline, affected services, and resolution steps, then draft a post‑mortem template.
• 4. Continuously analyze traffic with Script 4 to predict resource limits and trigger scaling actions before incidents occur.
