I have several services. I am instrumenting them using Zipkin.

In each module, in build.gradle is added a dependency to Zipkin:

 compile('org.springframework.cloud:spring-cloud-starter-zipkin')

In each module, in application.properties file are following settings:

spring.application.name=moduleX
spring.sleuth.sampler.percentage=0.2
spring.zipkin.base-url=http://localhost:9412

I call a specific endpoint that use other 3 modules, in total are 4 modules. Entire setup is on my laptop. I realized that Zipkin introduces a lot of overhead. I used Mozilla to compare the results. The small values are when Zipkin does not record the requests and the big value is when Zipkin records.

enter image description here Do you have any idea why there are so much overhead? Thank you.

1.You should check if your Zipkin Server is on.

2.You should check if the Span transfering is async.

In HTTP,Zipkin uses in-band transfer,all the information carried in HTTP headers.The cost time of generating Span is about 200 nanosecond.
