topsysproc(1m) USER COMMANDS topsysproc(1m)

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

SYNOPSIS
       ttooppssyysspprroocc [-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  the  root  user  or  users  with  the
       dtracekernel privilege can run this command.
