CronPulse: Guida agli alert per i fallimenti silenziosi
#python#automation#microsaas
Elimina per sempre i fallimenti silenziosi dei cron. Questo tutorial tecnico avanzato mostra come costruire un heartbeat watchdog self-hosted e pronto per la produzione in Go, sostituendo i costi SaaS da 80 $/mese. Esegui il wrap dei job CLI, rileva i blocchi silenziosi e invia alert istantanei su Slack e Discord con zero dipendenze. Include recipe complete per Docker e systemd.

"""CronPulse - Production-Ready Cron Heartbeat & Silent Failure Watchdog.
A zero-dependency CLI watchdog that wraps scheduled jobs, detects silent hangs,
captures non-zero exit codes, and routes real-time failure alerts to webhooks.
Features:
- Zero-dependency execution wrapper for CLI commands and shell scripts
- Configurable execution timeouts to catch silent background hangs
- Multi-channel webhook alert dispatching for Slack and Discord
- Detailed execution payload capturing stdout, stderr, and exit codes
- Self-contained environment variable parsing and payload formatting
Usage:
python main.py wrap --name "daily-backup" --timeout 300 -- ./backup.sh
python main.py ping --heartbeat-id "hb_123456" --status success
