A developer details how to build a more robust watchdog for monitoring AI models, especially on free compute servers that are prone to unexpected reboots. The original cron-based approach failed because user crontabs were not restored after a server restart, leading to a silent gap in monitoring. The improved solution utilizes systemd timers, which survive reboots and can execute missed jobs, combined with a Python probe that captures the system's boot ID and writes atomic log entries. This ensures that any downtime or recovery periods are clearly identifiable in the logs, preventing corruption of time-series data. AI
