  "system_prompt_fragment": "# Server Management\n\n> Server management principles for production operations.\n> **Learn to THINK, not memorize commands.**\n\n---\n\n## 1. Process Management Principles\n\n### Tool Selection\n\n| Scenario | Tool |\n|----------|------|\n| **Node.js app** | PM2 (clustering, reload) |\n| **Any app** | systemd (Linux native) |\n| **Containers** | Docker/Podman |\n| **Orchestration** | Kubernetes, Docker Swarm |\n\n### Process Management Goals\n\n| Goal | What It Means |\n|------|---------------|\n| **Restart on crash** | Auto-recovery |\n| **Zero-downtime reload** | No service interruption |\n| **Clustering** | Use all CPU cores |\n| **Persistence** | Survive server reboot |\n\n---\n\n## 2. Monitoring Principles\n\n### What to Monitor\n\n| Category | Key Metrics |\n|----------|-------------|\n| **Availability** | Uptime, health checks |\n| **Performance** | Response time, throughput |\n| **Errors** | Error rate, types |\n| **Resources** | CPU, memory, disk |\n\n### Alert Severity Strategy\n\n| Level | Response |\n|-------|----------|\n| **Critical** | Immediate action |\n| **Warning** | Investigate soon |\n| **Info** | Review daily |\n\n### Monitoring Tool Selection\n\n| Need | Options |\n|------|---------|\n| Simple/Free | PM2 metrics, htop |\n| Full observability | Grafana, Datadog |\n| Error tracking | Sentry |\n| Uptime | UptimeRobot, Pingdom |\n\n---\n\n## 3. Log Management Principles\n\n### Log Strategy\n\n| Log Type | Purpose |\n|----------|---------|\n| **Application logs** | Debug, audit |\n| **Access logs** | Traffic analysis |\n| **Error logs** | Issue detection |\n\n### Log Principles\n\n1. **Rotate logs** to prevent disk fill\n2. **Structured logging** (JSON) for parsing\n3. **Appropriate levels** (error/warn/info/debug)\n4. **No sensitive data** in logs\n\n---\n\n## 4. Scaling Decisions\n\n### When to Scale\n\n| Symptom | Solution |\n|---------|----------|\n| High CPU | Add instances (horizontal) |\n| High memory | Increase RAM or fix leak |\n| Slow response | Profile first, then scale |\n| Traffic spikes | Auto-scaling |\n\n### Scaling Strategy\n\n| Type | When to Use |\n|------|-------------|\n| **Vertical** | Quick fix, single instance |\n| **Horizontal** | Sustainable, distributed |\n| **Auto** | Variable traffic |\n\n---\n\n## 5. Health Check Principles\n\n### What Constitutes Healthy\n\n| Check | Meaning |\n|-------|---------|\n| **HTTP 200** | Service responding |\n| **Database connected** | Data accessible |\n| **Dependencies OK** | External services reachable |\n| **Resources OK** | CPU/memory not exhausted |\n\n### Health Check Implementation\n\n- Simple: Just return 200\n- Deep: Check all dependencies\n- Choose based on load balancer needs\n\n---\n\n## 6. Security Principles\n\n| Area | Principle |\n|------|-----------|\n| **Access** | SSH keys only, no passwords |\n| **Firewall** | Only needed ports open |\n| **Updates** | Regular security patches |\n| **Secrets** | Environment vars, not files |\n| **Audit** | Log access and changes |\n\n---\n\n## 7. Troubleshooting Priority\n\nWhen something's wrong:\n\n1. **Check if running** (process status)\n2. **Check logs** (error messages)\n3. **Check resources** (disk, memory, CPU)\n4. **Check network** (ports, DNS)\n5. **Check dependencies** (database, APIs)\n\n---\n\n## 8. Anti-Patterns\n\n| ❌ Don't | ✅ Do |\n|----------|-------|\n| Run as root | Use non-root user |\n| Ignore logs | Set up log rotation |\n| Skip monitoring | Monitor from day one |\n| Manual restarts | Auto-restart config |\n| No backups | Regular backup schedule |\n\n---\n\n> **Remember:** A well-managed server is boring. That's the goal.\n\n## When to Use\nThis skill is applicable to execute the workflow or actions described in the overview.",
