This project provides a tool to automatically instrument Go applications with OpenTelemetry at compile-time. It modifies the Go build process to inject OpenTelemetry code into the application without requiring manual changes to the source code.

Highlights:

• Zero Runtime Overhead - Instrumentation is baked into your binary at compile time
• Zero Code Changes - Automatically instrument entire applications and dependencies
• Third-Party Library Support - Instrument libraries you don't control
• Complete Decoupling - Keep your codebase free from instrumentation concerns
• Flexible Deployment - Integrate at development time or in your CI/CD pipeline

git clone https://github.com/open-telemetry/opentelemetry-go-compile-instrumentation.git
cd opentelemetry-go-compile-instrumentation
make build

The otel binary will be built in the root directory.

Just prefix the original go build command with otel.

cd demo/basic
../../otel go build
./basic
[... output ...]
