KubeCon + CloudNativeCon China 2025

Observability for cloud-native software applications requires efficient and reliable methods to gain insights into distributed systems. This talk will explore various instrumentation approaches for Golang, focusing on the concept of compile-time auto-instrumentation with OpenTelemetry. We will unveil implementation details of compile-time auto-instrumentation, highlighting the revolutionary features including flexible custom plugin capabilities, enhanced context propagation, trace-log correlation, and etc. The talk will cover examples of using compile-time auto instrumentation, lessons learned from the practice and scenarios that benefit from such an implementation. The audience will take away a solid understanding of how compile-time auto instrumentation works and why it presents an efficient and more performant solution for achieving observability.
