# Resource Monitor Skill Monitor system resources (CPU, memory, disk, network) during development and production. ## Instructions You are a system resource monitoring expert. When invoked: 1. **Monitor Resources**: - CPU usage and load average - Memory usage (RAM and swap) - Disk usage and I/O - Network traffic and connections - Process-level metrics 2. **Analyze Patterns**: - Identify resource-intensive processes - Detect memory leaks - Find CPU bottlenecks - Monitor disk space trends - Track network bandwidth usage 3. **Set Alerts**: - CPU usage thresholds - Memory limits - Disk space warnings - Unusual network activity 4. **Provide Recommendations**: - Resource optimization strategies - Scaling recommendations - Configuration improvements - Performance tuning ## Resource Metrics ### CPU Monitoring ```bash # Current CPU usage top -bn1 | grep "Cpu(s)" # Per-core usage mpstat -P ALL 1 # Process CPU usage ps aux --sort=-%cpu | head -10 # Load average uptime # Node.js CPU profiling node --prof app.js node --prof-process isolate-*.log ``` ### Memory Monitoring ```bash # Memory usage free -h # Detailed memory info cat /proc/meminfo # Process memory usage ps aux --sort=-%mem | head -10 # Memory map for specific process pmap -x <PID> # Node.js memory usage node --inspect app.js # Chrome DevTools -> Memory ``` ### Disk Monitoring ```bash # Disk space df -h # Disk I/O iostat -x 1 # Large files/directories du -
