Once you download and install DAE (dynaTrace Ajax Edition), you must go to the Programs group in the Start menu and find dynaTrace. Obviously, the first thing to do is to enter a url link. Next, click the button of the play icon, select "New Run Configuration", and enter a new URL.
One of the features of DAE is that it can run under a multi-page workflow. You can enter the starting URL and then navigate to other web pages or start Ajax features, while DAE monitors everything in the background. When you close IE browser, you can analyze all the information collected by DAE.
The main features that distinguish DAE from other tools: In-depth analysis of JavaScript. By detecting event triggers and JavaScript API calls, the timeline is divided into different parts. It contains HTTP waterfall charts. Another feature is the ability to save DAE analysis results so you can review them afterwards and share them with colleagues. It also has some other interesting features, such as automatically formatting the streamlined source code so that you can view a more understandable version when debugging the streamlined code on site. You can also analyze CPU usage and page rendering performance
When you need to analyze performance issues caused by JavaScript, dynaTrace Ajax Edition contains code details from high-level calls to actual execution. You can see which line of JavaScript code is causing the performance bottleneck of the page . I recommend you test this tool and add it to your performance testing toolkit.
