OpenWrt is a powerful, flexible Linux-based firmware for routers and embedded devices. Its package system allows you to extend your device’s functionality with a wide range of software. This page introduces several handy packages for advanced network management, monitoring, and troubleshooting.

== Installed Packages Overview ==

The following packages are recommended for enhanced routing, traffic management, monitoring, and system diagnostics:

* '''pbr''' & '''luci-app-pbr''':
Policy-Based Routing (PBR) enables you to define granular rules for directing specific traffic through different WAN interfaces or VPNs. The luci-app-pbr package provides an easy-to-use web interface for configuring these policies.

* '''luci-app-sqm''':
Smart Queue Management (SQM) helps reduce bufferbloat and keeps latency low, especially on congested connections. The LuCI app allows you to easily configure and monitor SQM from the web interface.

* '''luci-app-nlbwmon''':
Netlink Bandwidth Monitor (nlbwmon) tracks per-host network usage and presents bandwidth statistics over time through the LuCI web interface. This is useful for monitoring which devices consume the most data.

* '''irqbalance''':
A background daemon that distributes hardware interrupts across multiple CPU cores for better performance on multi-core routers and virtualized environments.

* '''tcpdump''':
A powerful command-line packet analyzer for capturing and inspecting network traffic.

* '''htop''':
An interactive process viewer for monitoring CPU, memory, and running processes.

* '''iftop''':
A real-time bandwidth monitor that displays network usage per connection.

* '''prometheus-node-exporter-lua''':
Lightweight Prometheus Node Exporter written in Lua, providing system metrics (CPU, RAM, network, etc.) over HTTP for Prometheus scraping and monitoring.

= Installation and Enabling irqbalance =

To install all recommended packages and enable irqbalance, run:

<syntaxhighlight lang="bash">
opkg update
opkg install pbr luci-app-pbr luci-app-sqm luci-app-nlbwmon irqbalance tcpdump htop iftop prometheus-node-exporter-lua

# Enable irqbalance in the config file
echo "config irqbalance 'irqbalance'
option enabled '1'" > /etc/config/irqbalance

# Start and enable irqbalance service
/etc/init.d/irqbalance enable
/etc/init.d/irqbalance start
</syntaxhighlight>

= Quick Usage Tips =

;Policy-Based Routing (PBR)
: Configure routing rules via LuCI: '''Network → PBR - Policy-Based Routing'''.
: Direct specific devices or traffic types through VPNs or alternate WANs.

;SQM
: Enable and configure via LuCI: '''Network → SQM QoS'''.
: Set download/upload rates slightly below your actual speeds for best results.

;Bandwidth Monitoring
: View per-host usage via LuCI: '''Status → Bandwidth Monitor''' (requires luci-app-nlbwmon).

;IRQ Balance
: After enabling '''irqbalance''', check interrupt distribution with:
<syntaxhighlight lang="bash">
cat /proc/interrupts
</syntaxhighlight>
: You should see interrupts handled by multiple CPU cores.

;Traffic Analysis
: Capture packets:
<syntaxhighlight lang="bash">
tcpdump -i <interface> -ne
</syntaxhighlight>
: Replace <interface> with your WAN or LAN interface name.

;System Monitoring
: Run '''htop''' or '''iftop''' from the command line for live system and network stats.

;Prometheus Node Exporter
: After installing '''prometheus-node-exporter-lua''', metrics are available at:
: <nowiki>http://<router-ip>:9100/metrics</nowiki>
: Add your router as a scrape target in your Prometheus server configuration.
