Server Dashboard - Quick Health Check

PURPOSE

Provide instant overview of server health without digging through multiple commands.

WHEN TO USE

• TRIGGERS:
  • "サーバー状況" / "サーバーの状態"
  • "server status" / "server health"
  • "システム確認"
  • "何か問題ある？" (in server context)

WORKFLOW

1. Gather system metrics (parallel when possible)
2. Check critical services
3. Scan recent logs for errors
4. Format into dashboard view
5. Highlight any issues
