Re: [ns] trace analyzer

[George Riley <riley@cc.gatech.edu>]

I used the attached program(s) to analyze the trace files "on the fly" and
produce various summary reports.  There are two attached, readtr2 which
does some tcp goodput calculations, and queuelog which monitors queue
behavior.  I use the tcl open command to create a pipe, which then
receives the trace data as it is generated and produces the desired
reports:

set tf [open "|./queuelog -" w]
$ns trace-all $tf

Many postings to the mailing list discuss how to use awk to produce
similar results...I prefer this method since I'm better at C/C++ than awk,
but expect the awk method is equally useful when done correctly.

Hope this helps.

George
