Agreed, SmokePing is exactly what you want. You will have to change the step and pings settings to allow collecting data at the resolution you want, but otherwise it gives you what you need by wrapping RRDTool with ping data collection (as well as a number of other probes) and a visualization tool for graphing.

Note that you could accomplish something similar on your own (see http://www.void.gr/kargig/blog/2007/03/21/round-trip-and-packet-loss-stats-with-rrdtool/) but with SmokePing already available you might as well use that.

Subject: [Bloat] Plotting ping times in real time?

Has anyone written a Linux program that plots ping times in real time?
I.e. that gives the same information as running ping in an extra window
(with no -c argument), but graphically?

It would be helpful when manually tweaking an AQM.
