I've not really used listeners beside aggregate graph/report, view results tree, and some jmeterplugins.org ones. Came to know listeners don't work in CLI mode (e.g. https://www.blazemeter.com/blog/top-2-techniques-get-jmeter-test-results-non-gui-mode )
I recently came across an interesting post: http://www.testautomationguru.com/jmeter-real-time-results-influxdb-grafana the author apparently modified the jmeter core package's Summariser component to be able to also work like the backend listener in GUI mode. Unfortunately so far, it appears he/she only released the compiled changes, but not the source code. Anyone do anything similar? It would be nice to base/build upon that for other data analysis purposes other than send to influxdb. And I'd rather not have to figure things out from scratch & reinventing the wheel via poking through the jmeter source code head on.
