An OpenTelemetry compliant SDK -1. Instrumented by auto-instrumentation (serializable into OTLP JSON) -2. Lightweight -3. User-friendly - -These design choices are listed in the order of their importance. - -The primary design goal of this module is to be an OpenTelemetry SDK. -This means that it needs to implement the Go APIs found in `go.opentelemetry.io/otel`. - -Having met the requirement of SDK compliance, this module needs to provide code that the `go.opentelemetry.io/auto` module can instrument. -The chosen approach to meet this goal is to ensure the telemetry from the SDK is serializable into JSON encoded OTLP. -This ensures then that the serialized form is compatible with other OpenTelemetry systems, and the auto-instrumentation can use these systems to deserialize any telemetry it is sent. - -Outside of these first two goals, the intended use becomes relevant. -This package is intended to be used in the `go.opentelemetry.io/otel` global API as a default when the auto-instrumentation is running. -Because of this, this package needs to not add unnecessary dependencies to that API. -Ideally, it adds none. -It also needs to operate efficiently. - -Finally, this module is designed to be user-friendly to Go development. -It hides complexity in order to provide simpler APIs when the previous goals can all still be met. diff --git a/vendor/go.opentelemetry.io/auto/sdk/LICENSE b/vendor/go.opentelemetry.io/auto/sdk/LICENSE deleted file mode 100644 index 261eeb9e9..000000000 --- a/vendor/go.opentelemetry.io/auto/sdk/LICENSE +++ /dev/null @@ -1,201 +0,0 @@ - Apache License - Version 2.0, January 2004 - http://www.apache.org/licenses/ - - TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION - - 1.
