Subject RE: Requests per second/minute monitor?
Date Wed, 16 May 2007 18:02:12 GMT
Adding entries to RequestHandlerBase.getStatistics() sounds like it
might be a reasonable compromise; backwards compatibility is kept in
place but everything from now on gets the added advantages of more
tracking.  So far I've added (because I need)

avgTimePerRequest
avgRequestsPerSecond

I agree that you can pull this kind of information from logs but jmx
accessibility + the built in stats page make life a good bit simpler
especially in distributed environments.

Are there any others that people think would be nice to have or should I
stop all together?

Yeah, I held off on that as it seemed that timing/statistics might be  
handleable on a larger scale.  OTOH, it does give an easy way to  
requesthandlers to insert detailed timing data in a logical place in  
the output.
