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.

OPTIONS

-C: don't clear the screen
-s: print per second values

EXAMPLES

Default output, 1 second updates,: # topsysproc
Print every 5 seconds,: # topsysproc 5
Print a scrolling output,: # topsysproc -C

FIELDS

load avg: load averages, see uptime(1)
syscalls: total syscalls in this interval
syscalls/s: syscalls per second
PROCESS: process name
COUNT: total syscalls in this interval
COUNT/s: syscalls per second

NOTES

There may be several PIDs with the same process name.

DOCUMENTATION

See the DTraceToolkit for further documentation under the Docs directory. The DTraceToolkit docs may include full worked examples with verbose descriptions explaining the output.

EXIT

topsysproc will run until Ctrl-C is hit.
