-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.
