oPrifile required to vmlinux it's not avaliable in ubuntu 12.04
you need to install some kerenel related packages
If there is no -dbg package:
Create an /etc/apt/sources.list.d/ddebs.list by running the following line at a terminal:
echo "deb http://ddebs.ubuntu.com $(lsb_release -cs) main restricted universe multiverse" | \
sudo tee -a /etc/apt/sources.list.d/ddebs.list
Stable releases (not alphas and betas) require three more lines adding to the same file, which is done by the following terminal command:
echo "deb http://ddebs.ubuntu.com $(lsb_release -cs)-updates main restricted universe multiverse
deb http://ddebs.ubuntu.com $(lsb_release -cs)-security main restricted universe multiverse
deb http://ddebs.ubuntu.com $(lsb_release -cs)-proposed main restricted universe multiverse" | \
sudo tee -a /etc/apt/sources.list.d/ddebs.list
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 428D7C01
Easiest way to obtain vmlinux under Ubuntu is to add ddebs repository and install kernel debug symbols:
sudo apt-get install linux-image-$(uname -r)-dbgsym
vmlinux then can be found here:
file/usr/lib/debug/boot/vmlinux-$(uname -r)
Download oprofile
=================
http://prdownloads.sourceforge.net/oprofile/oprofile-0.9.8.tar.gz
tar -xzvf oprofile-0.9.8.tar.gz
cd oprofile-0.9.8
sudo apt-get install libpopt-dev binutils-dev
./configure && make && make install
Moniter pertucular pid --callgraph
=======================
operf --vmlinux=/usr/lib/debug/boot/vmlinux-3.2.0-33-generic --pid 18079 --callgraph
--callgraph means create call graph
-c categorizes samples by cpu
-t seeing per-thread samples in multi-threaded applications.
Getting Call graph with nice graph
===================================
http://gprof2dot.jrfonseca.googlecode.com/git/gprof2dot.py
apt-get install python graphviz
opreport -cl --callgraph --image-path=/lib/modules/3.2.0-33-generic/ | ./gprof2dot.py -f oprofile | dot -Tpng -o output.png
check call graph
================

<maynard> he profiling daemon is currently active, so changes to the configuration
<maynard> will be used the next time you restart oprofile after a --shutdown or --deinit.
<maynard> dhanasekaran, Let's start from the beginning. Do the following commands:
<maynard> opcontrol --deinit
<maynard> opcontrol --reset
<maynard> opcontrol --start
<maynard> then run your hadoop or whatever you want to profile
<maynard> then opcontrol --deinit
<maynard> then 'opreport --long-filenames' to show summary of executables that were profiled
<maynard> then, from the summary output, pick the executable pathname of interest and do:
<maynard> opreport --callgraph <exe_pathname>
