unable to profile with oprofile

[ebsunny]

Hi,


I am using cent os 5.5 .

Linux localhost.localdomain 2.6.18-164.el5xen #1 SMP Thu Sep 3 04:03:03 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux

I am trying to profile my project(server) with oprofile written in c++.

So, for that i am using eclipse Helios Service Release 2 and it has a plugin for oprofile. I have installed the plugin through eclipse. but when i try to profile with oprofile a message box pop up saying that,

"An error has occurred. See error log for more details.
java.lang.ExceptionInInitializerError"



I have also tried with eclipse plugin gprof. It creates the gmon.out file but unfortunately it did not take any sample. It can only show the number of times a function is called but it couldnt show the duration of time a function executes. Can pls anyone tell me why this is happening ?


can anyone tell me if cent os kernel support profiling with oprofile.


My project is a server written in c++. It has shared libraries and it is multithreaded.It is not much efficient. So i am trying to find out where it is spending much time and where it is overloading the cpu.

It would be a gr8 help if anyone can tell me how i can profile my server with oprofile or gprof in eclipse in a proper way.I am prefering eclipse because it shows the gmon.out or the output of oprofile in much more understandable way.


Thank you
