Free pnrg software for linux

pNRG project is a package for maintaining and visualizing network data, particularly suited for historical trend analysis of network resources.

pNRG doesnt need any explicit configuration and is able to auto-discover, mantain and graph new resources (either IPv4/IPv6 end hosts, network segments, MAC addresses, Autonomous Systems, etc.) as soon as they produce a traffic footprint.

pNRG at a glance:

* Easily displays network data collected through pmacct, regardless of the data source, ie. the network itself, NetFlow or sFlow.
* Straight to your preferred web browser from a couple of pmaccts memory plugins, without the need to configure or define anything.
* No need to rotate, mantain or update anything once the package is in place.
* Just a working installation of pmacct, RRDtool and an Apache supporting execution of CGIs are required.

While it has been over-simplified, specifically tailored to network usage and written from the scratch, most of its concepts are deeply rooted inside the NRG project. For the task, pNRG gets data from a couple of pmaccts memory plugins and relies over RRDTool for graphs and CGIs.
