Shameless plug: A friend of mine, Felix Barnsteiner, wrote a profiler for Java based applications, called stagemonitor [1]. He started working on it in 2013 for his masters thesis. Since then, he steadily worked on it in the company as well as in his spare time. Some months ago, he implemented support for distributed tracing. Stagemonitor implements Open Tracing. It also collects frontend performance data, called end user monitoring. They get correlated automatically. And the best thing about it: stagemonitor is free and open source (APL).
