# openwrt-munin-node
|
||||
openwrt-oriented munin-node implementation inspired by muninlite
|
||||
|
||||
## Quick installation guide
|
||||
Install `munin-node`:
|
||||
|
||||
`mkdir -p /usr/local/bin /etc/munin-node
|
||||
cd /etc/munin-node
|
||||
wget -O munin-node.tar.gz https://github.com/MaffC/openwrt-munin-node/archive/master.tar.gz
|
||||
tar xzf munin-node.tar.gz plugins.d
|
||||
tar xzf munin-node.tar.gz munin-node -C /usr/local/bin/
|
||||
rm munin-node.tar.gz`
|
||||
|
||||
Install dependencies for included plugins as needed:
|
||||
|
||||
`opkg update
|
||||
opkg install perl curl iwinfo`
|

Plugins should be installed in this directory, and should have purely alphanumeric names. Plugins can, as with all munin-node implementations I've seen, be written in any supported language, however as this munin-node implementation specifically targets OpenWRT, sh-compatible/ash-specific shellscript is recommended.
|
||||
Plugins in this directory may be enabled/disabled as needed by either adding or removing the executable permission (chmod +x, chmod -x).
|
||||
|
||||
The following plugins were originally provided with muninlite (http://sourceforge.net/projects/muninlite/) and have been altered to varying degrees to act as generic plugins. These plugins and the muninlite project are licensed under the GPLv2 and are included for completion's sake.
|
||||
- df
|
||||
- if
|
||||
- interrupts
|
||||
- irqstats
|
||||
- memory
|
||||
|
||||
The following plugins were originally provided with muninlite, but have been largely rewritten and may resemble their original in graph configuration only:
|
||||
- cpu
|
||||
- uptime
|
||||
|
||||
The following plugins have been written to more specifically monitor the functions of an OpenWRT router installation, and are licensed under the 3-clause BSD license:
|
||||
- dhcp - Tracks the current count of valid DHCP leases.
|
||||
- dns - Tracks caching/forwarding statistics in the dnsmasq caching resolver
|
||||
- load - Tracks system load for the past one, five and fifteen minutes, as well as active and running processes.
|
||||
- netstats - Tracks currently-open TCP, UDP, ICMP and other connections. A netstats plugin is provided with muninlite, however it is related only in name to this.
|
||||
- ping - Tracks outbound latency and packet loss to a single host, intended to measure outbound connection quality/uptime through an ISP.
|
||||
- skysr102 - Tracks ADSL line attenuation/noise and sync speeds. This plugin is specific to the Sky SR102 modem-router and may not work on other devices.
|
||||
- upnp - Tracks the current count of valid UPnP forward leases
|
||||
- wireless - Tracks total connected stations across all wireless interfaces, as well as signal and noise levels for each interface/AP.
