I Built a Monitor for Servers. Then Pointed It at Myself.
TL;DR: A developer builds Nightwatch, a sleep-friendly alerting system for server health inspired by a past project. It uses a gate and an LLM to decide if a notification is worth waking up for, then sends alerts via Telegram.
The author reuses a previous pattern (workers-monitor) to monitor servers with a Cloudflare Worker, hourly checks, and a deterministic threshold. An LLM (Claude Haiku) filters noise by judging whether an event is worth attention. If the gate trips and the LLM approves, a Telegram alert is sent; otherwise, no notification. The concept is extended from monitoring events to evaluating their significance to the human operator, not just reporting every change.
Question for the room: Have you built a notification or alerting system that decides when to wake you up or interrupt you, and what criteria did you use to separate important events from noise?
