+✅ **Metrics Command**: Now provides comprehensive real system metrics including:
+  - **System Metrics**: CPU count, model, usage; Memory (total, used, available, cached, buffers); Disk usage; Network gateway; Uptime
+  - **Performance Metrics**: Load average (1min, 5min, 15min); Process statistics (total, running, sleeping, stopped, zombie); I/O statistics; Memory pressure; Failed services
+  - **CLI Options**: --system, --performance, --all (defaults to --all if no option specified)
+  - **Real Data**: Reads from /proc filesystem, system commands (df, ip, ps, systemctl) for accurate system information
+  - **Status**: ✅ COMPLETE - No longer a placeholder, provides real comprehensive system monitoring capabilities
