Extrace is a graphical analysis tool used to analyze trace output from x-Sim simulations. Extrace is used specifically for analyzing router buffers and ethernet driver traces.
Invoking the "extrace" tool:
extrace [arguments] [plot-types] trace-filename
plot-types:
queue port0 port1
args: Same as in ptcp:
-allplot -header -tail -a -o -xbeg= -xend= -xtime= -xtics= -maxRate= (can use T1, Kb and Mb) -maxTics= -journal -pn -n -big -auto1 -auto2new:
-group=<#>Group events into groups of size #. For example, if the queue information of a router was written every 10ms, a grouping of 5 would be equivalend to writing the information every 50ms.
-bucket=<#>Used for the histograms printed out to the screen. Specifies the bucket size of the histogram.
-reset=<time>Reset gathering of statistics, so the numbers shown only represent statistics after time (in ms).
-db=<filename>Writes information to the specified (db) file.
