This is the first release of micrometer-tracing, it depends on micrometer-core:2.0.0-M1, you can find the documentation here.
Micrometer Tracing provides a simple facade for the most popular tracer libraries, letting you instrument your JVM-based application code without vendor lock-in. It is designed to add little to no overhead to your tracing collection activity while maximizing the portability of your tracing effort.
It also provides a tracing extension to Micrometer’s TimerRecordingHandler (starting from Micrometer 2.0.0-M1 version). Whenever a Timer.Sample is used, a corresponding span will be created, started, stopped and reported.
