Max has been working on monitoring statistics from with the wifi router using collectd and RRD.
Max discussed with ChrisJ about system wide monitoring... recommends Icinga.

Icinga
Interesting article: [Setting up Icinga on a Debian Server to Remotely Monitor an OpenWrt Router]
Icinga is a Nagios fork which, as of Fall 2013, has more development involvement. Icinga is the central system that pings other systems like openWRT. Icinga gathers the data and can track and send notifications when values drift beyond normal tolerances. On the remote hosts it is required to install nrpe and a basic set of nrpe plugins. The article referenced above shows how it is possible to install nrpe on openwrt through the openwrt web interface. After that one can ssh into the router and configure it.
Once the router is configured it is necessary to configure the central Icinga server with:
- the IP address of each node it will track
- the host groups
- the services that are to be monitored.
OpenWRT Package: nrpe
Package: nrpe Version: 2.12-4 Depends: libc, librt, libpthread, libopenssl, libwrap Source: feeds/packages/admin/nrpe SourceFile: nrpe-2.12.tar.gz SourceURL: @SF/nagios Section: admin Architecture: ib42x0 Installed-Size: 19018 Filename: nrpe_2.12-4_ib42x0.ipk Size: 19801 MD5Sum: f36019344c747a1e88f5aab50776bd4e Description: The NRPE addon is designed to allow you to execute Nagios plugins on remote Linux/Unix machines. The main reason for doing this is to allow Nagios to monitor "local" resources (like CPU load, memory usage, etc.) on remote machines. Since these public resources are not usually exposed to external machines, an agent like NRPE must be installed on the remote Linux/Unix machines.
