Can you use strace ?

Code:
STRACE(1)                                               STRACE(1)

NAME
       strace - trace system calls and signals

SYNOPSIS
       strace [ -dffhiqrtttTvxx ] [ -acolumn ] [ -eexpr ] ...  [ -ofile ] [ -ppid
       ] ...  [ -sstrsize ] [ -uusername ] [ command [ arg ...  ] ]

       strace -c [ -eexpr ] ...  [ -Ooverhead ] [ -Ssortby ] [ command [ arg  ...
       ] ]

DESCRIPTION
       In the simplest case strace runs the specified command until it exits.  It
       intercepts and records the system calls which are called by a process  and
       the  signals  which  are  received  by a process.  The name of each system
       call, its arguments and its return value are printed on standard error  or
       to the file specified with the -o option.

       strace  is a useful diagnostic, instructional, and debugging tool.  System
       adminstrators, diagnosticians and trouble-shooters will find it invaluable
       for  solving  problems  with  programs for which the source is not readily
       available since they do not need to be recompiled in order to trace  them.
       Students,  hackers  and the overly-curious will find that a great deal can
       be learned about a system and its system calls by  tracing  even  ordinary
       programs.   And  programmers will find that since system calls and signals
       are events that happen at the user/kernel interface, a  close  examination
       of  this  boundary  is  very useful for bug isolation, sanity checking and
       attempting to capture race conditions.

       STRACE_LOG
	      Output file name prefix of files produced by a strace -ff -tt[t] command.

NOTES

       strace-log-merge  does  not work well with strace logs generated by strace -tt invocation that pass midnight, as those lack the information
       required for the proper sorting.  Employing the -ttt option in the respective strace invocation should solve the problem.

BUGS

       strace-log-merge does not perform any checks whether the files specified are in the correct format and implies that only files from a  sin-
       gle strace session match STRACE_LOG.*  glob pattern.

HISTORY

       The initial version of strace-log-merge was written by Denys Vlasenko in 2012.

REPORTING BUGS

       Problems with strace-log-merge should be reported to the strace mailing list at <strace-devel@lists.sourceforge.net>.
