Wily Technology Releases Browser Response Time Adapter

Wily continues to lead the market for J2EE Applications Performance Management by doing things the right way. A critical element of any APM solution is the measurement of actual end user experience. For J2EE applications which have a web server as the front end, one right way to measure end user experience is to measure how long the application system takes to respond to each user request. Since each user request comes in the form of a URL, measuring the arrival time of that URL and then the gap to the response on the part of the application system to that URL is one of the "right" way to do things. Of course, Wily does not stop at the measurement of just the response time, since the IntroScope product can then drill into the middle tier components on J2EE applications servers to find out why response time has degraded.

Wily is also correct in its approach of not relying upon synthetic transactions (scripted agents emulating real users). APM Experts believes that while a script may be useful during QA, and it might be useful as a beginning of the day check (to see if the system is working before real users log on), there is no way that scripts can be written to accurately emulate what real users do. It is also extremely difficult to use scripted synthetic agents to emulate the combination of actions that a set of production users take on a live application system. Please see the article "Why are Scripts and Synthetic Transactions Undesirable" in the Analysis section of the APM Experts web site for more details on this subject.
