Any kind of Request Recorder/Player available?
With Apache JMeter, they have a proxy that you can use to record a session with the server, and you can then use that as a basis for load testing and what not. What I'm looking for is something similar, but something that I can ideally place in Tomcat (as a Valve perhaps, or a Servlet filter). Basically, something that records the entire incoming request and then stores it out in a format that can later be played back by another tool. The problem is that we have a server than has a production memory leak, and the profilers are basically worthless in production. But if I can place a logger and record a days traffic, and then replay it against a test server (with all the monitoring etc.), then I can more easily reproduce the problem without heavily impacting performance of the production server. Anyone have any ideas? Regards, Will Hartung ([EMAIL PROTECTED]) - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Any kind of Request Recorder/Player available?
That's a really interesting question... I don't know of anything that exists, although I'm quite certain something does. :) I can however think it through, and its probably not a huge chore to build... As you mentioned, a filter would probably do the trick nicely... if we assume your app only deals in POSTs and GETs of basic user input (because things like multiparts and such would complicate matters a bit), then it's really just a simple filter that iterates over all parameters and stores them. Just a simple CSV file of name=value pairs would suffice, with each line being a request. Then it should be a simple matter to write a Java app using the standard JDK classes to run through that CSV file and make the requests with the parameters you recorded. -- Frank W.

netbeans.org has a http monitor module that can record and playback of http requests, plugged into netbeans' web development framework. I think you could just download just that module and manually install it into your tomcat, and use the UI from netbeans to do the record/playback. It actually can be installed into any newer application server that is up to date in its servlet support. go to http://monitor.netbeans.org for more details --George On 7/15/05, Frank W.
