  • The semantic conventions v1.39.0 release introduces breaking changes, including:

    • rpc span and metric attributes have been renamed to align with naming guidelines:
      • rpc.system → rpc.system.name (values: grpc, grpc_web, connectrpc, thrift, dubbo, etc.)
      • rpc.method and rpc.service have been merged into a fully-qualified rpc.method attribute
      • rpc.client|server.duration → rpc.client|server.call.duration (unit changed to seconds)
      • rpc.grpc.request.metadata/rpc.grpc.response.metadata → rpc.request.metadata/rpc.response.metadata
      • rpc.grpc.status_code → deprecated in favor of rpc.response.status_code
      • rpc.jsonrpc.request_id → jsonrpc.request.id
      • rpc.jsonrpc.version → jsonrpc.protocol.version
    • system and process metrics:
      • *.linux.memory metrics renamed to *.memory.linux
      • system.process.status → process.state
      • system.paging.type and process.paging.fault_type → system.paging.fault.type
    • peer.service attribute has been deprecated in favor of service.peer.name

    See semantic-conventions v1.39.0 release and v1.38.0 release for complete breaking change details.

Deprecated

• ServiceAttr() function in go.opentelemetry.io/contrib/instrumentation/github.com/aws/aws-sdk-go-v2/otelaws is deprecated. Use MethodAttr() instead, as rpc.service has been merged into rpc.method in semantic conventions v1.39.0. (#8404)
• OperationAttr() function in go.opentelemetry.io/contrib/instrumentation/github.com/aws/aws-sdk-go-v2/otelaws is deprecated. Use MethodAttr() instead, as rpc.service has been merged into rpc.method in semantic conventions v1.39.0. (#8404)

Removed

• The deprecated DefaultClient, Get, Head, Post, and PostForm in go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp. Use a custom *http.Client with otelhttp.NewTransport(http.DefaultTransport) instead. (#8266)
• The deprecated WithPublicEndpoint in go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp. Use WithPublicEndpointFn instead. (#8267)
• The deprecated WithRouteTag in go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp. The route is already added automatically for spans. For metrics, the alternative is to use the WithMetricAttributesFn option. (#8268)
