The Solo Founder's $0 Monitoring Stack (Everything I Use Is Boring and Free)

说明与用途

零成本监控堆栈：进程监督、健康检查、死人的开关、自我修复和每日摘要。

问题

One-person operations often incur high observability costs or rely on complex tools, leading to unnecessary expenses and maintenance overhead.

结果

Implemented a zero‑cost monitoring stack that caught all revenue‑affecting failures over several months, with 90% of incidents resolved automatically on the first attempt and a 90% reduction in interruption load from daily digests.

工作流

• 1. Use launchd (macOS) or systemd (Linux) to supervise critical processes, ensuring automatic restarts and journald logging.
• 2. Run a lightweight Python script that pings each critical URL every 5 minutes, appending status and latency to a JSONL file and alerting only on state changes.
• 3. Configure a free uptime service to receive a heartbeat POST every minute; if 3 heartbeats are missed, the service emails the owner.
• 4. On failure, execute a self-healing loop: restart the process, clear cache, re-authenticate, with a maximum of 3 attempts logged; only then ping the owner.
• 5. Send a single daily digest email summarizing checks, failures, auto-heals, and human-required actions, keeping live alerts for critical incidents only.

证据

This is the layer people skip, and it's the one that catches the day your whole box silently dies.

Roughly 90% of incidents die at attempt 1 and never reach me.
