Build a Self-Healing System in 100 Lines of Python

说明与用途

一段100行Python脚本，自动检测并修复常见系统问题，减少80%的人工干预。

问题

Incidents in production systems often require manual intervention, causing downtime and alert fatigue.

结果

Implemented a compact, rule‑based self‑healing daemon that automatically resolved 80% of incidents, reducing manual intervention and improving uptime.

工作流

• 1. Monitor system metrics via subprocess calls (top, df, systemctl).
• 2. Evaluate each rule’s check lambda against thresholds.
• 3. If a rule triggers and cooldown elapsed, execute its heal function.
• 4. Log heal actions and update last_heal timestamps.
• 5. Optionally verify post‑heal state before proceeding.

证据

I built a self‑healing layer that handled 80% of incidents automatically.
