AutoMeter is a X11/Xt/Xaw application scanning and representing Linux (tm) /proc/* and more metrics in a automatically optimal scalling Athena Widget, called AutoScale. AutoScale is full color and has many representation options.
NeTraMet is an implementation of the Meter MIB (RFC2720-2723).
In short: a programmable network traffic meter.
Reading information from NeTraMet for further processing can be a challenge.
mr2mysql should make that easier by automatically reading flows
