These look like a lot of new scripts, and not quite what I was doing with DTrace, although in the same spirit that DTrace pioneered: tracing of TCP internals for custom metrics. I didn't create DTrace, but I did create the DTrace TCP provider and many networking scripts. A nice list of them is here: http://dtracebook.com/index.php/Network_Lower_Level_Protocols#Scripts http://dtracebook.com/index.php/Network_Lower_Level_Protocol... . My scripts focused on tracing events, workload characterization at different levels, and some timing: connection lifespans, and 1st byte latency. (At least in that location; I've got DTrace scripts scattered elsewhere too). The tcpdive scripts have focused so far on perturbation study: congestion, retransmissions, resets. Also useful!
