Question 1

How to integrate Micrometer Tracing with Spring Boot?

Accepted Answer

Add the micrometer-tracing dependency and a backend adapter like OpenTelemetry or Brave in your pom.xml or build.gradle, then configure tracing properties in application.yml for auto-configuration to handle setup seamlessly.

Question 2

Micrometer Tracing vs OpenTelemetry directly?

Accepted Answer

Micrometer Tracing offers a vendor-neutral API to abstract over OpenTelemetry and others, ideal for avoiding lock-in, while using OpenTelemetry directly provides more native features and control for teams committed to that ecosystem.

Question 3

Can I switch tracing backends easily with Micrometer Tracing?

Accepted Answer

Yes, by swapping dependencies and adjusting configuration, you can switch between supported backends like OpenZipkin Brave and OpenTelemetry without changing instrumentation code, thanks to its facade design.

Question 4

How does Micrometer Tracing handle async context in reactive apps?

Accepted Answer

It uses built-in context propagation mechanisms to maintain trace continuity across threads and asynchronous boundaries, ensuring spans are linked properly in reactive or multi-threaded environments.

Question 5

What's the performance overhead of Micrometer Tracing?

Accepted Answer

The abstraction layer adds minimal overhead, but for ultra-high-performance applications, direct backend usage might be slightly faster; however, for most cases, the trade-off is negligible compared to the flexibility gained.

Question 6

How to contribute to the Micrometer Tracing project?

Accepted Answer

Refer to the Contributing Guide in the repository, use the spring-javaformat plugin for code formatting, and join the Micrometer Slack for discussions, as mentioned in the README.
