I'd suggest looking at netperf. It doesn't measure the queue directly; it measures the latency that queue occupancy induces. However, at least in commercial equipment, this thing we call "the queue" may not be all in the same place...

I am using the fq_codel, codel, and pie qdiscs for my research and am wondering if there is a way to collect statistics regarding the average queue length since a qdisc was enabled? I have looked at tc's "-s" flag for statistics, but they show nothing about queue length and I have been unable to find anything else that might help me get queue length statistics. Best, Ryan Doyle
