Extrace

 

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
                                -auto2
new:
-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.
lenDb[r|w]
To be documented.
