• LuCI web interface

From Source (Recommended)

# 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

# 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)
disk	Filesystem usage and I/O statistics
network	Interface stats and connection tracking
processes	Process list and counts
sensors	Temperature sensor readings
system	System information (hostname, kernel, uptime)

Customization

Modifying Refresh Rate

Edit the poll interval in the view files:

// 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.
