procsystime
procsystime(1m) USER COMMANDS procsystime(1m)NAME
procsystime - analyse system call times. Uses DTrace.
SYNOPSIS
procsystime [-acehoT] [ -p PID | -n name | command ]
DESCRIPTION
procsystime prints details on system call times for processes, both the elapsed times and on-cpu times can be printed.
The elapsed times are interesting, to help identify syscalls that take some time to complete (during which the process may have slept). CPU
time helps us identify syscalls that are consuming CPU cycles to run.
Since this uses DTrace, only users with root privileges can run this command.
OPTIONS -a print all data
-c print syscall counts
-e print elapsed times, ns
-o print CPU times, ns
-T print totals
-p PID examine this PID
-n name
examine processes which have this name
EXAMPLES
Print elapsed times for PID 1871,
# procsystime -p 1871
Print elapsed times for processes called "tar",
# procsystime -n tar
Print CPU times for "tar" processes,
# procsystime -on tar
Print syscall counts for "tar" processes,
# procsystime -cn tar
Print elapsed and CPU times for "tar" processes,
# procsystime -eon tar
print all details for "bash" processes,
# procsystime -aTn bash
run and print details for "df -h",
# procsystime df -h
FIELDS
SYSCALL
System call name
TIME (ns)
Total time, nanoseconds
COUNT Number of occurrences
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
procsystime will sample until Ctrl-C is hit.
