I am a senior undergraduate student at the University of North Carolina at Chapel Hill and am studying the effectiveness of AQMs. I have set up a lab network and plan on running different sets of experiments with different AQMs. My router machines are running Linux kernel version 3.16.0.

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.
