topsysproc
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 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 ver- bose descriptions explaining the output. EXIT
topsysproc will run until Ctrl-C is hit. AUTHOR
