Populate InstrumentationScope fields in trace output#131
Conversation
Set InstrumentationScope.Name to the module path
("github.com/andrewh/motel"), Version to the build version, and
SchemaURL to the OTel semconv schema URL. Previously these fields
used the service name as the tracer name and left Version/SchemaURL
empty, which doesn't match the OTel spec's intent for scope fields.
…tributes Shows users that InstrumentationScope.Attributes can carry metadata about the instrumentation library itself.
Summary of ChangesHello, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed! This pull request significantly improves the OpenTelemetry trace output by populating the InstrumentationScope fields with more precise and comprehensive metadata. It configures the tracer to include the module path, build version, and the OpenTelemetry semantic conventions schema URL, along with a synthetic attribute for demonstration. These changes ensure that generated trace data is richer and more informative, aiding in better observability and debugging. Highlights

Code Review
This pull request correctly populates the InstrumentationScope fields in the trace output, aligning with OpenTelemetry best practices. A security audit confirmed that no new vulnerabilities were introduced, and user-supplied inputs are handled securely. My review also includes a critical fix for an invalid import path that would break the build, and a suggestion to refactor duplicated code for better maintainability.
