It's tentatively called Bucket listener which is probably not a good name. It provides information about the distribution of response times.
You define a series of intervals and then it behaves in much the same way as the summary element in the postprocessor menu only I've put it under the listener menu. Each time a sample occurs it looks at the time and increments the appropriate counter. I used a binary search to find the correct interval so it shouldn't have too much effect on the amount of load j-meter can generate even with a large number of intervals. It then prints to the console window and the log file. You can specify the intervals manually in a table or you can just tell it the upper and lower limits and the number of intervals you want and will work them out itself. It uses the same property as the summariser to tell it when to report. I couldn't get it working as a separate jar file so I added the classes to the apache core.jar The classes are org.apache.jmeter.reporters.BucketListenerModel org.apache.jmeter.reporters.BucketResultCollector org.apache.jmeter.visualizers.Bucket org.apache.jmeter.visualizers.BucketSet org.apache.jmeter.visualizers.BucketListener I would like to get this added to j-meter if possible. I want to know what the procedure is for submitting this addition and what the standards for acceptance are. I would also like to know if people think it is a good idea and if they find it useful. My motivation in doing this was that I wanted to be able to run a large number of samples (millions) against a website and have some knowledge of response time distribution without having to store every result. I'm reasonably pleased with it. I'm a tester rather than a programmer so my code may well be a bit odd. I would be more than happy to receive criticism of my code should someone have the time spare to have a look at it. You can download the files from here if you are interested http://www.box.net/p/james96046 There are two files one is a built ApacheJmeter_core.jar with the bucket listener in it and the other is just the source for it.
