It works great. Please keep us posted on further updates.

I was just about to post a message about how to set up a Markov style load model in JMeter using the various types of controllers and branching logic. I will spend tomorrow setting up and using your controllers.

It adds two new logic controllers ("Markov Session Controller", "Markov State") representing a session model for an application and its states. Transitions between states can then be assigned guards (conditions) and actions (e.g. variable assignments) known from state machines. The transition probabilities are specified within external behavior model files (CSV files containing the transition matrix; templates can be generated conveniently). A mix of behavior models with associated relative frequencies of their occurence during a test execution can be specified. Moreover, the number of threads can be varied based on mathematical formulae e.g. specified using a BeanShell script. I implemented Markov4JMeter as a JMeter component (Jar file) which is installed by simply adding it to JMeter's lib/ext folder (it requires at least JRE 1.5). It is licensed under the Apache 2.0 license. The release (binary and source) including a tutorial (for getting a first idea) can be downloaded from http://markov4jmeter.sourceforge.net/ I would be glad if this extension is helpful to someone else. Feedback is greatly appreciated!
