v4.8.0

What's Changed

• Support tracing OTLP exporter.
  • Remove Honeycomb exporter because it can be configured via OTLP.
  • Breaking change to env var OTEL_EXPORTERS, renamed to OTEL_TRACES_EXPORTER per OTel config spec.

by @Baliedge in #127.

v4.7.1

What's Changed

• Simplify log level usage by converting log level parameters to constant enum type. This type mirrors logrus.Level exactly so it can be easily converted (e.g. level := tracing.Level(logrus.GetLevel())).
• Breaking Change: This is a breaking change to the tracing.WithLevel() option.
• Fix documentation around meaning of level numbers.
• Tag spans with log.level=<name> and log.levelNum=<n>.
• Using StartScopeError() will also tag span in error status.

by @Baliedge in #126.

v4.7.0

What's Changed

• Breaking Change to tracing package.
  • Changed InitTracing() signature to reference optional tracing-specific options, instead of OpenTelemetry-specific options. This allows more flexibility to extend configuration within tracing.
• Log level tracing.
  • Defaults to log level set in Logrus.
  • Use variants of StartScopeInfo(), StartScopeDebug(), etc.
  • Spans created with lesser severity will be dropped from the trace.
  • See tracing/README.md for details.
• Add TypedError for describing an error with type classification. tracing
• Add Prometheus metrics.

v4.3.1

What's Changed

• Simplify most common use case of OTel initialization using tracing.NewResource().

before:

res, err := resource.Merge(
       resource.Default(),
       resource.NewWithAttributes(
               semconv.SchemaURL,
               semconv.ServiceNameKey.String("My service"),
               semconv.ServiceVersionKey.String("v1.0.0"),
       ),
)
ctx, tracer, err := tracing.InitTracing(ctx, "github.com/myrepo/myservice", sdktrace.WithResource(res))

after:

res, err := tracing.NewResource("My service", "v1.0.0")
ctx, tracer, err := tracing.InitTracing(ctx, "github.com/myrepo/myservice", sdktrace.WithResource(res))
