|
### Prerequisites
|
|
|
|
- OpenWrt 21.02 or later
|
|
- LuCI web interface
|
|
|
|
### From Source (Recommended)
|
|
|
|
```bash
|
|
# Clone into OpenWrt build environment
|
|
cd ~/openwrt/feeds/luci/applications/
|
|
git clone https://github.com/YOUR_USERNAME/luci-app-netdata-dashboard.git
|
|
|
|
# Update feeds and install
|
|
cd ~/openwrt
|
|
./scripts/feeds update -a
|
|
./scripts/feeds install -a
|
|
|
|
# Enable in menuconfig
|
|
make menuconfig
|
|
# Navigate to: LuCI > Applications > luci-app-netdata-dashboard
|
|
|
|
# Build package
|
|
make package/luci-app-netdata-dashboard/compile V=s
|
|
```
|
|
|
|
### Manual Installation
|
|
|
|
```bash
|
|
# Transfer package to router
|
|
scp luci-app-netdata-dashboard_1.0.0-1_all.ipk root@192.168.1.1:/tmp/
|
|
|
|
# Install on router
|
|
ssh root@192.168.1.1
|
|
opkg install /tmp/luci-app-netdata-dashboard_1.0.0-1_all.ipk
|
|
|
|
# Restart services
|
|
/etc/init.d/rpcd restart
|
|
/etc/init.d/uhttpd restart
|
|
```
|
|
|
|
## Usage
|
|
|
|
After installation, access the dashboard at:
|
|
|
|
**Status → Netdata Dashboard**
|
|
|
|
The dashboard has four tabs:
|
|
1. **Real-time**: Overview with gauges and sparklines
|
|
2. **System**: Detailed system information
|
|
3. **Network**: Interface statistics
|
|
4. **Processes**: Process monitor
|
|
|
|
Data refreshes automatically every 2 seconds.
|
|
|

## API Endpoints
|
|
|
|
| Method | Description |
|
|
|--------|-------------|
|
|
| `stats` | Quick overview (CPU%, memory%, load, etc.) |
|
|
| `cpu` | Detailed CPU statistics and per-core data |
|
|
| `memory` | Memory breakdown (total, free, buffers, cached) |
|

|
|
## Customization
|
|
|
|
### Modifying Refresh Rate
|
|
|
|
Edit the poll interval in the view files:
|
|
|
|
```javascript
|
|
// In realtime.js
|
|
poll.add(L.bind(this.refresh, this), 2); // 2 seconds
|
|
```
|
|
|
|
### Adding Custom Metrics
|
|
|
|
Extend the RPCD backend script at `/usr/libexec/rpcd/netdata` to add new data sources.
