## Installation
### Prerequisites
- Python 3.8 or higher
- pip (Python package manager)
- Modern web browser (Chrome, Firefox, Safari, Edge)
### Step 1: Clone or Navigate to the Directory
```bash
cd "Storage Dashboard"
```
### Step 2: Install Python Dependencies
```bash
cd backend
pip install -r requirements.txt
```
### Step 3: Start the Backend Server
```bash
python app.py
```
The server will start on `http://localhost:5000`
### Step 4: Access the Dashboard
Open your web browser and navigate to:
```
http://localhost:5000
```
## Usage
### Dashboard Interface
1. **System Information Panel**
- View OS details and system uptime
- Located at the top of the dashboard
2. **Disk Partitions Section**
- Each partition displayed as a card
- Color-coded progress bars:
- Blue: < 75% usage (healthy)
- Orange: 75-90% usage (warning)
- Red: > 90% usage (critical)
3. **I/O Performance Charts**
- Bar charts show current read/write speeds and IOPS
- View all disks simultaneously
4. **Detailed Statistics Table**
- Comprehensive I/O metrics in tabular format
- Sortable and easy to read
5. **SMART Health Section**
- Individual cards for each storage device
- Health status badges (Good/Warning/Bad)
- Detailed device information
6. **Historical Performance**
- Line charts track performance over time
- Shows trends for the last 20 data points
- Auto-updates every 5 seconds
### Manual Refresh
Click the "Refresh Now" button in the header to manually update all metrics.
## API Endpoints
The backend provides the following REST API endpoints:
| Endpoint | Method | Description |
|----------|--------|-------------|
| `/api/metrics` | GET | Get all metrics in one call |
| `/api/partitions` | GET | Get disk partition information |
| `/api/io-stats` | GET | Get I/O statistics |
| `/api/smart` | GET | Get SMART health data |
| `/api/system-info` | GET | Get system information |
### Example API Response
```json
{
"timestamp": "2024-01-15T10:30:00",
"system_info": {
"platform": "Linux",
"hostname": "server-01",
"uptime_days": 15,
"uptime_hours": 6,
"uptime_minutes": 23
},
"partitions": [
{
"device": "/dev/sda1",
"mountpoint": "/",
"fstype": "ext4",
"total_gb": 500.0,
"used_gb": 250.0,
"free_gb": 250.0,
"percent": 50.0
}
],
"io_stats": [
{
"disk": "sda",
"read_speed_mbps": 45.2,
"write_speed_mbps": 23.1,
"iops_read": 1200,
"iops_write": 800
}
]
}
```
## Configuration
### Change Refresh Interval
Edit `frontend/dashboard.js`:
```javascript
const REFRESH_INTERVAL = 5000; // milliseconds (5 seconds)
```
### Change Historical Data Length
Edit `frontend/dashboard.js`:
```javascript
const HISTORY_LENGTH = 20; // number of data points
```
### Change Server Port
Edit `backend/app.py`:
```python
app.run(debug=True, host='0.0.0.0', port=5000)
```
## SMART Data Collection
SMART data provides valuable insights into disk health but requires elevated privileges:
### Linux
```bash
sudo python app.py
```
### Windows
Run Command Prompt or PowerShell as Administrator:
```bash
python app.py
```
### macOS
```bash
sudo python app.py
```
If SMART data is unavailable, the dashboard will display a message indicating that root/admin privileges are required.
## Troubleshooting
### Backend Won't Start
- Ensure Python 3.8+ is installed: `python --version`
- Verify all dependencies are installed: `pip install -r requirements.txt`
- Check if port 5000 is available
### No Data Displayed
- Ensure the backend server is running
- Check browser console for errors (F12)
- Verify the API URL in `dashboard.js` matches your backend
### SMART Data Not Available
- SMART data requires root/admin privileges
- Run the backend with elevated permissions
- Some virtual machines may not expose SMART data
### Charts Not Rendering
- Ensure you have internet connectivity (Chart.js loads from CDN)
- Check browser console for JavaScript errors
- Try clearing browser cache
## Security Considerations
- The dashboard runs on `0.0.0.0` (all interfaces) by default
- For production use, configure proper firewall rules
- Consider using HTTPS for secure connections
- Implement authentication for sensitive environments
## Development
### Project Structure
```
Storage Dashboard/
├── backend/
│ ├── app.py # Flask application
│ ├── metrics_collector.py # Metrics collection logic
│ └── requirements.txt # Python dependencies
└── frontend/
├── index.html # Main dashboard page
├── styles.css # Styling
└── dashboard.js # Frontend logic and charts
```
### Extending the Dashboard
#### Add New Metrics
1. Add collection method in `metrics_collector.py`
2. Create API endpoint in `app.py`
3. Update frontend to display the new data
#### Customize Appearance
- Modify `styles.css` to change colors and layout
- Update CSS variables in `:root` for theme changes
## Performance
- **Low overhead** - Minimal impact on system performance
- **Efficient polling** - Only collects data when needed
- **Optimized charts** - Smooth animations and updates
- **Responsive design** - Fast load times
## Browser Compatibility
- Chrome/Edge 90+
- Firefox 88+
- Safari 14+
- Opera 76+
## License
This project is open source and available for personal and commercial use.
## Contributing
Contributions are welcome! Feel free to:
- Report bugs
- Suggest new features
- Submit pull requests
- Improve documentation
## Support
For issues or questions:
1. Check the Troubleshooting section
2. Review the API documentation
3. Examine browser console logs
4. Check backend server logs
## Future Enhancements
Planned features:
- [ ] Export metrics to CSV/JSON
- [ ] Email/SMS alerts for critical conditions
- [ ] Multi-server monitoring
- [ ] Historical data persistence
- [ ] Custom metric thresholds
- [ ] Network storage support
- [ ] Docker containerization
## Screenshots
