I want to have a listener that will take a value say 10 for the sake of argument and divide it into ten intervals 1,2,3,4,5,6,7,8,9,10 in this case. For each interval it will have a variable.
As j-meter runs it will perform comparisons. And increment the variable associated with the interval into which the response time falls. This information could ultimately be graphed in the j-meter gui but for the time being I would be happy just to output these values to the log. I thought I would try basing my code on the SimpleDataWriter which extends the AbstractVisualiser My theory was that I would just be able to add a data structure and work my funky magic from the addSample method. Unfortunately I have fallen at the first hurdle and have failed to make it appear in the gui. I have got a class BucketWriter which is based on simple datawriter (I changed the class name and put it in a different package) I added a System.out.println(); to the addSample method in the hope I would be able to see this and be sure everything was working and make progress from there. As far as I can tell Abstract Visualiser is supposed to deal with getting things into the menu system with the getMenuCategories() method which is set to say this is a listener. I put the jar file containing only my class file into the lib directory. Is the package name important? So I would be grateful to know 1) how to get the thing appearing and 2) is it a good idea. The idea of course is to get an idea of the distribution of response times without storing vast amounts of data. For 10 buckets I anticipate it ought to be pretty quick as we can put a value in a bucket with only three comparisons if we do a binary search. Would it be a crazy idea to try this for 100 buckets thus ending up with 100 values stored per test and 10 or so comparisons needed? My thinking is it would not be a good idea to try to set the max value automatically as you would have to keep all the samples in memory which is clearly daft. So if you have specified a silly number and all you results are in the final bucket then you just specify a bigger number and run the test again. I also thought it might be a good idea to specify start and finish values rather than just an end value and assuming a start interval of 0-whatever. Any comments welcome. Thanks, James
