pNRG is a package for maintaining and visualizing
network data, particularly historical trend
analysis of network resources. It doesn't need any
explicit configuration and is able to
auto-discover, maintain, and graph new resources
(either IPv4/IPv6 end hosts, network segments, MAC
addresses, Autonomous Systems, etc.) as soon as
they produce a traffic footprint. It gets data
from pmacct and relies on RRDTool and Apache for
graphs and CGIs.
