Simply make use of jQuery whenever you can. Ask a question. Quick access. Search related threads. Remove From My Forums. Answered by:. Then, you will browse a web application while Ajax View monitors its function-level performance, and see the resulting profile information. Our prototype is often rough around the edges, not as fast as it could be, not scalable, etc. If you are running Windows Vista, you should see a dialog asking you to allow Ajax View to run with administrator privileges.

Click allow. Because Ajax View does not require browser plugins or ActiveX controls, it can profile and monitor app behavior as they run in either Internet Explorer or Firefox. Ajax View works by using a proxy to intercept and rewrite the JavaScript code of a web application and automatically inject instrumentation code. The rewriting is controlled by one or more instrumentation policies, embedded within the proxy.

In this demo, you have seen a simple performance profiling policy that adds log statements to the beginning and end of every script block and function definition within the JavaScript code of a web application. This rewriting policy takes a script that looks like:.

Our prototype actually does a little more rewriting than is shown here. For example, it inlines the logging functions to reduce performance overhead, rewrites return statements, and keeps track of the line number and character offset of the function to help identify anonymous functions and disambiguate functions with the same name. Whenever the injected instrumentation logs an event, such as a function enter or exit, the event is timestamped and added to a queue. A timer event handler periodically empties the queue of messages and reports them back to the proxy via an HTTP post request.

The proxy is responsible for analyzing the results and generating the per-function performance statistics. Collectives on Stack Overflow. Learn more. Ask Question. Asked 10 years, 4 months ago. Active 10 years, 4 months ago.
