Heartbeat-мониторинг cron-job'ов: dead-man-switch на FastAPI

Обычный uptime-мониторинг проверяет, отвечает ли сервис на запросы. Cron-job ничего не отвечает — он запускается раз в N часов, делает работу и молча завершается. Если cron перестал запускаться (uptime daemon упал, машина в read-only mode после fsck, disk full) — обычный мониторинг этого не видит. Решение известно с 70-х — паттерн dead-man-switch (он же heartbeat). Я недавно делал heartbeat-эндпоинты для Valpero. Здесь разберу серверную часть на FastAPI + клиентский bash-pattern, и edge-кейсы которые их ломают. В конце готовый код, который можно адаптировать под свой стек.

🤡 Oh wow, a #YouTube video claims the #CIA has a "magic" #sensor that can detect heartbeats from 60 km away. 🚀 Meanwhile, the only thing being detected is the viewer's #brain #cells #disappearing as they watch this #nonsense. 📉

22 протокола мониторинга в PingZen: от пинга до Playwright-сценариев

Вам точно нужен только HTTP-мониторинг? А как насчёт проверки, что DNS резолвится правильно, SMTP-сервер принимает почту, а Minecraft-сервер отвечает на handshake? В PingZen мы добавили 22 протокола, включая Transaction с Playwright, чтобы вы могли мониторить буквально всё. Рассказываю, зачем это нужно и как работает «под капотом».
