NAME
       topsysproc - top syscalls by process name. Uses DTrace.

SYNOPSIS
       topsysproc [-Cs] [interval [count]]

DESCRIPTION
       This  program continually prints a report of the number of system calls
       by process name, and refreshes the display every 1 second or as	speci‐
       fied at the command line. Similar data can be fetched with "prstat -m".

       Since  this  uses  DTrace, only users with root privileges can run this
       command.
