-n event_count -- only display the first event_count number of top events.

-q -- run quietly, only really makes sense with -r option.

-r csv_file -- output gathered data in a comma separated values file. This can be then imported and graphed using your favourite open source spread sheet.

-s -- report short process name from /proc/pid/cmdline in CSV output.This reports just the process name.

-l -- report long process name from /proc/pid/cmdline in CSV output. This reports the process name and all the command line arguments.

-C -- report the sample event count in the CSV output rather than the default events per second rate.

-S -- report the minimum, maximum, average and population standard deviation at the end of the CSV output.

-d -- strip full directory path off the process name in the CSV output.

-t threshold -- ignore samples where the event delta per second less than the given threshold.

-c -- report cumulative events rather than events per sample period.
