dappprof

dappprof(1m)							   USER COMMANDS						      dappprof(1m)

NAME

       dappprof - profile user and lib function usage. Uses DTrace.

SYNOPSIS

       dappprof [-acehoTU] [-u lib] { -p PID | command }

DESCRIPTION

       dappprof  prints  details  on  user  and  library call times for processes as a summary style aggragation. By default the user fuctions are
       traced, options can be used to trace library activity. Output can include function counts, elapsed times and on cpu times.

       The elapsed times are interesting, to help identify functions 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 function counts

       -e     print elapsed times, ns

       -o     print CPU times, ns

       -T     print totals

       -p PID examine this PID

       -u lib trace this library instead

       -U     trace all library and user functions

EXAMPLES

       run and examine the "df -h" command,
	      # dappprof df -h

       print elapsed times, on-cpu times and counts for "df -h",
	      # dappprof -ceo df -h

       print elapsed times for PID 1871,
	      # dappprof -p 1871

       print all data for PID 1871,
	      # dappprof -ap 1871

FIELDS

       CALL   Function call name

       ELAPSED
	      Total elapsed time, nanoseconds

       CPU    Total on-cpu 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

       dappprof will sample until Ctrl-C is hit.
