+# Monitor Nezha Redesign
+## Summary
+Redesign the monitor overview to resemble Nezha dashboard by introducing a Server Matrix (Grid) containing cards with metrics visualisations. 
+
+## Objectives
+- [x] Analyze `monitor-view.tsx` layout boundaries. 
+- [x] Create `ServerCard` utilizing `Progress` component.
+- [x] Render metrics (CPU, RAM, Disk, System Load, Connections, Network speeeds).
+- [x] Implement robust real-time updates and seamless state linkage via existing hooks.
+- [x] Adjust layout positioning for impact at top-of-page.
+
+## Technical Details
+Injected a `ServerCard` inline component mapping over unified node metric states. Used the tailwind and hero UI components matching visual designs like progress bars and small monospace typograhy. Extracted utility color scales.
+
+## Status: Complete
