Spring Cloud Sleuth is loosely based on HTrace but is compatible with Zipkin (Dapper).</li><li class="listitem">Sleuth records timing information to aid in latency analysis.
By using sleuth, you can pinpoint causes of latency in your applications.</li><li class="listitem"><p class="simpara">Sleuth is written to not log too much and to not cause your production application to crash.
To that end, Sleuth:</p><div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: circle; "><li class="listitem">Propagates structural data about your call graph in-band and the rest out-of-band.</li><li class="listitem">Includes opinionated instrumentation of layers such as HTTP.</li><li class="listitem">Includes a sampling policy to manage volume.</li><li class="listitem">Can report to a Zipkin system for query and visualization.</li></ul></div></li><li class="listitem">Instruments common ingress and egress points from Spring applications (servlet filter, async endpoints, rest template, scheduled actions, message channels, Zuul filters, and Feign client).</li><li class="listitem">Sleuth includes default logic to join a trace across HTTP or messaging boundaries.
For example, HTTP propagation works over Zipkin-compatible request headers.
