Is there a way to find out how long it takes for websphere process a request

Question

I have an issue where I need to monitor how long it takes for Websphere to process a request. Specifically I need to know how much time is spent in the "application world", that is time spent processing code in the ear file.

I can't just compute request_time - reponse_time because that contains time spent in the container or what I call "websphere world". I need to know the time spent only in the ear file.

Is there some performance setting I can toggle in websphere so this information gets logged to the server system log file? The application does not have log4j.

I am using Websphere 6.1

Take a look at the PMI interface under the WAS admin console. It provides some performance metrics -- not the prettiest or easiest interface, but it might provide what you're looking for.

A monitoring plugin is often used to do this. My company uses Introscope via a WAS JBM plugin, and it provides a better interface than PMI for viewing the performance data. Of course, it isn't free, but there may be free or cheap alternatives that are better than PMI.
