>>One of the weaknesses of JMeter is the lack of graphs and historization of these Graphs, Graphite listener is an answer to it.
I fully agree there is a gap between measurements collection and processing/reporting. In our company there is a need of performance repository and we are weighting the options. I believe JMeter plugin-like interface between injector and performance repository would enable live monitoring of sytem under test. One can parse raw csv/xml results and upload for the analysis, however it is likely to create big latency gap between collection and the visualization. In general, I would love to see performance repository integration in JMeter itself or in JMeter-plugins. To be fair, I did not yet look into the proposed listener. It is not clear if commons-math (and other new dependencies) fits JMeter's needs. I do not think 1-5MiB download increase make any difference, however performance defects or concurrency problems do. It is not good at all if commons-math/pool/etc breaks under heavy threaded load. Are there benchmarks to see max achieved througput? (e.g. max number of listened events using all the cores) What latency does listener add? (e.g. max throughput in single thread) Regards, Vladimir Sitnikov
