OpenTelemetry - CNCF/opentelemetry-dotnet: Release 1.5.1-beta.1

Name: opentelemetry-dotnet

Owner: OpenTelemetry - CNCF

Release: 1.5.1-beta.1 of instrumentation libraries

Released: 2023-07-21

License: Apache-2.0

Release Assets:

For all the four instrumentation libraries: AspNetCore, HttpClient, GrpcNetClient, SqlClient:

  • The new HTTP and network semantic conventions can be opted in to by setting the OTEL_SEMCONV_STABILITY_OPT_IN environment variable. This allows for a transition period for users to experiment with the new semantic conventions and adapt as necessary. The environment variable supports the following values:
    • http - emit the new, frozen (proposed for stable) HTTP and networking attributes, and stop emitting the old experimental HTTP and networking attributes that the instrumentation emitted previously.
    • http/dup - emit both the old and the frozen (proposed for stable) HTTP and networking attributes, allowing for a more seamless transition.
    • The default behavior (in the absence of one of these values) is to continue emitting the same HTTP and network semantic conventions that were emitted in 1.5.0-beta.1.
    • Note: this option will eventually be removed after the new HTTP and network semantic conventions are marked stable. At which time this instrumentation can receive a stable release, and the old HTTP and network semantic conventions will no longer be supported. Refer to the specification for more information regarding the new HTTP and network semantic conventions for both spans and metrics.

  • Fixed an issue affecting NET 7.0+. If custom propagation is being used and tags are added to an Activity during sampling then that Activity would be dropped. (#4637)
