Install systemtap on Ubuntu

As you may not be able to find the correct kernel debug info from the ddebs source, it is better you can compile it from source:

sudo apt-get install systemtap
sudo apt-get install systemtap-sdt-dev

cd $HOME
sudo apt-get install dpkg-dev debhelper gawk
mkdir tmp && cd tmp
sudo apt-get build-dep --no-install-recommends linux-image-$(uname -r)
apt-get source linux-image-$(uname -r)
cd linux-3.13.0
fakeroot debian/rules clean
AUTOBUILD=4 fakeroot debian/rules binary-generic skipdbg=false

then use dpkg -i to install the compiled .ddeb file.

Also recommend to install module debug info:

sudo apt-get install elfutils

Then reboot your server...
