Zipkins(in spring boot Application) is not storing all the trace id's when i am sending 10 request from an application to other application

I am using ZIPKINS for distributed tracing the problem is when I am trying to test ZIPKINS by sending 10 request at a time to that service from other service by using loop, checked the UI for the logs of that, I had got only 2 logs i.e for first and last, I haven't received logs of the remaining requests. Can you help in figuring out what is the problem in that. Trace ids and span ids are generated for all the request, I am unable to see that logs for the same. Logs that are received:

Log format is: [application name, traceId, spanId, export]

So the last value true/false is actually the export value which means:

Export – This property is a boolean that indicates whether or not this log was exported to an aggregator like Zipkin. Zipkin is beyond the scope of this article but plays an important role in analyzing logs created by Sleuth.

As export values are false, zipkin is not receiving those values. That is expected behavior.

Root Cause: Some of the logs are exporting and some are not is because of sampler rate. Not all of the logs are meant to be sent. Anyway if you want all of the logs to be sampled try adding this property:

spring.sleuth.sampler.probability=1.0
