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 users with root privileges can run this command.
