What is this javascript or networking monitoring tool?
<p>I just found an interesting article on ajaxian.com.</p>

<p>the article is <a href="http://blog.dynatrace.com/2011/03/22/testing-and-optimizing-single-page-web-2-0ajax-applications-why-best-practices-alone-dont-work-any-more/" rel="nofollow">http://blog.dynatrace.com/2011/03/22/testing-and-optimizing-single-page-web-2-0ajax-applications-why-best-practices-alone-dont-work-any-more/</a></p>

<p>i wonder the name of the tool he is using.</p>

<p>Anyone knows its name?</p>

<p>P.S: Can I post a question like this?? </p>
