Dynatrace has had the Real Time Business Transaction Data Feed for a while. Most users used it to stream data to Splunk or other external BI Solutions. Andreas Grabner built a very handy tool that can consume that Real Time Data Feed and for instance aggregate Business Transaction Result measures for every split value. His first use for this tool is live streaming of load test results to e.g: back to your load testing tool.

Test it out for yourself and let us know what other use cases you come up with. Download it from the Real Time Data Feed Listener GitHub Page.
