The following is a demonstration of the dappprof command,

This is the usage for version 0.60,

# dappprof -h

USAGE: dappprof [-cehoTU] [-u lib] { -p PID | command }

-p PID # examine this PID

-a # print all details

-c # print syscall counts

-e # print elapsed times (us)

-o # print on cpu times

-T # print totals

-u lib # trace this library instead

-U # trace all libraries + user funcs

-b bufsize # dynamic variable buf size

eg,

dappprof df -h # run and examine "df -h"

dappprof -p 1871 # examine PID 1871

dappprof -ap 1871 # print all data

The following shows running dappprof with the "banner hello" command.

Elapsed and on-cpu times are printed (-eo), as well as counts (-c) and

totals (-T),

# dappprof -eocT banner hello

# # ###### # # ####

The above output has analysed user functions (the default). It makes it

easy to identify which function is being called the most (COUNT), which

is taking the most time (ELAPSED), and which is consuming the most CPU (CPU).

These times are totals for all the functions called.
