Load testing a Rails application with Tsung
First, RTFM :-) http://tsung.erlang-projects.org/user_manual.html
Installing erland and Tsung
Tsung is written in erlang and uses perl libraries to generate graphics.
sudo apt-get install -Y erlang
sudo apt-get install gnuplot-nox
sudo apt-get install libtemplate-perl libhtml-template-perl libhtml-template-expr-perl
wget http://www.process-one.net/downloads/tsung/1.2.1/tsung-1.2.1.tar.gz
tar xvf tsung-1.2.1.tar.gz && rm tsung-1.2.1.tar.gz
rm -R tsung-1.2.1.tar.gz && rm tsung-1.2.1.tar.gz
cd tsung-1.2.1
./configure
make
sudo make install
Set up Tsung
Check out the examples in /usr/share/doc/tsung/examples

Mozilla/5.0 (Windows; U; Windows NT 5.2; fr-FR; rv:1.7.8) Gecko/20050511 Firefox/1.0.4
Run tsung with:
tsung start
Starting the Tsung recorder
Configure your browserIf you use your machine as tsung client and also for the webserver, don't forget to remove "localhost" from the "No proxy For" textfield otherwise all requests to your web application will bypass the proxy server used by the tsung recorder!
Commands:
tsung recorder
tsung stop_recorder
Then you just have to copy the xml file generated the recoreder in ~/.tsung/
Generating the html report
