Server management principles and decision-making. Process management, monitoring strategy, and scaling decisions. Teaches thinking, not commands.
インストールする前に、エージェントに与えられる指示の中身を確認できます。
Server management principles for production operations. Learn to THINK, not memorize commands.
| Scenario | Tool |
|---|---|
| Node.js app | PM2 (clustering, reload) |
| Any app | systemd (Linux native) |
| Containers | Docker/Podman |
| Orchestration | Kubernetes, Docker Swarm |
| Goal | What It Means |
|---|---|
| Restart on crash | Auto-recovery |
| Zero-downtime reload | No service interruption |
| Clustering | Use all CPU cores |
| Persistence | Survive server reboot |
| Category | Key Metrics |
|---|---|
| Availability | Uptime, health checks |
| Performance | Response time, throughput |
| Errors | Error rate, types |
| Resources | CPU, memory, disk |
| Level | Response |
|---|---|
| Critical | Immediate action |
| Warning | Investigate soon |
| Info | Review daily |
| Need | Options |
|---|---|
| Simple/Free | PM2 metrics, htop |
| Full observability | Grafana, Datadog |
| Error tracking | Sentry |
| Uptime | UptimeRobot, Pingdom |
| Log Type | Purpose |
|---|---|
| Application logs | Debug, audit |
| Access logs | Traffic analysis |
| Error logs | Issue detection |
| Symptom | Solution |
|---|---|
| High CPU | Add instances (horizontal) |
| High memory | Increase RAM or fix leak |
| Slow response | Profile first, then scale |
| Traffic spikes | Auto-scaling |
| Type | When to Use |
|---|---|
| Vertical | Quick fix, single instance |
| Horizontal | Sustainable, distributed |
| Auto | Variable traffic |
| Check | Meaning |
|---|---|
| HTTP 200 | Service responding |
| Database connected | Data accessible |
| Dependencies OK | External services reachable |
| Resources OK | CPU/memory not exhausted |
| Area | Principle |
|---|---|
| Access | SSH keys only, no passwords |
| Firewall | Only needed ports open |
| Updates | Regular security patches |
| Secrets | Environment vars, not files |
| Audit | Log access and changes |
When something's wrong:
| ❌ Don't | ✅ Do |
|---|---|
| Run as root | Use non-root user |
| Ignore logs | Set up log rotation |
| Skip monitoring | Monitor from day one |
| Manual restarts | Auto-restart config |
| No backups | Regular backup schedule |
Remember: A well-managed server is boring. That's the goal.

Create aesthetically beautiful interfaces following proven design principles. Use when building UI/UX, analyzing designs from inspiration sites, generating design images with ai-multimodal, implementing visual hierarchy and color theory, adding micro-interactions, or creating design documentation. Includes workflows for capturing and analyzing inspiration screenshots with chrome-devtools and ai-multimodal, iterative design image generation until aesthetic standards are met, and comprehensive design system guidance covering BEAUTIFUL (aesthetic principles), RIGHT (functionality/accessibility), SATISFYING (micro-interactions), and PEAK (storytelling) stages. Integrates with chrome-devtools, ai-multimodal, media-processing, ui-styling, and web-frameworks skills.
