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



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 specified at the command line. Similar  data  can  be  fetched  with
       "prstat -m".

       Since  this  uses  DTrace,  only the root user or users with the dtrace_kernel privilege can run this
       command.

       -s     print per second values


EXAMPLES

              # topsysproc

       Print every 5 seconds,
              # topsysproc 5

       Print a scrolling output,
              # topsysproc -C
