1.6.0-beta.3 of instrumentation libraries

OpenTelemetry.Instrumentation.AspNetCore

• Removed the Activity Status Description that was being set during exceptions. Activity Status will continue to be reported as Error. This is a breaking change. EnrichWithException can be leveraged to restore this behavior. (#5025)

• Updated http.request.method to match specification guidelines.

  • For activity, if the method does not belong to one of the known values then the request method will be set on an additional tag http.request.method.original and http.request.method will be set to _OTHER.
  • For metrics, if the original method does not belong to one of the known values then http.request.method on http.server.request.duration metric will be set to _OTHER

  http.request.method is set on http.server.request.duration metric or activity when OTEL_SEMCONV_STABILITY_OPT_IN environment variable is set to http or http/dup. (#5001)

• An additional attribute error.type will be added to activity and http.server.request.duration metric when the request results in unhandled exception. The attribute value will be set to full name of exception type. The attribute will only be added when OTEL_SEMCONV_STABILITY_OPT_IN environment variable is set to http or http/dup. (#4986)

• Fixed network.protocol.version attribute values to match the specification. (#5007)

• Calls to /metrics will now be included in the http.server.request.duration metric. This change may affect Prometheus pull scenario if the Prometheus server sends request to the scraping endpoint that contains /metrics in path. (#5044)

• Fixes the http.route attribute for scenarios in which it was previously missing or incorrect. Additionally, the http.route attribute is now the same for both the metric and Activity emitted for a request Lastly, the Activity.DisplayName has been adjusted to have the format {http.request.method} {http.route} to conform with the specification. There remain scenarios when using conventional routing or Razor pages where http.route is still incorrect. See #5056 and #5057 for more details. (#5026)

• Removed network.protocol.name from http.server.request.duration metric as per spec. (#5049)

OpenTelemetry.Instrumentation.Http

• Removed the Activity Status Description that was being set during exceptions. Activity Status will continue to be reported as Error. This is a breaking change. EnrichWithException can be leveraged to restore this behavior. (#5025)

• Updated http.request.method to match specification guidelines.

  • For activity, if the method does not belong to one of the known values then the request method will be set on an additional tag http.request.method.original and http.request.method will be set to _OTHER.
  • For metrics, if the original method does not belong to one of the known values then http.request.method on http.client.request.duration metric will be set to _OTHER

  http.request.method is set on http.client.request.duration metric or activity when OTEL_SEMCONV_STABILITY_OPT_IN environment variable is set to http or http/dup. (#5003)

• An additional attribute error.type will be added to activity and http.client.request.duration metric in case of failed requests as per the specification.

  Users moving to net8.0 or newer frameworks from lower versions will see difference in values in case of an exception. net8.0 or newer frameworks add the ability to further drill down the exceptions to a specific type through HttpRequestError enum. For lower versions, the individual types will be rolled in to a single type. This could be a breaking change if alerts are set based on the values.

  The attribute will only be added when OTEL_SEMCONV_STABILITY_OPT_IN environment variable is set to http or http/dup. (#5005) (#5034)

• Fixed network.protocol.version attribute values to match the specification. (#5006)

• Set network.protocol.version value using the protocol version on the received response. If the request fails without response, then network.protocol.version attribute will not be set on Activity and http.client.request.duration metric. (#5043)

OpenTelemetry.Instrumentation.SqlClient

• Updated Microsoft.Extensions.Configuration and Microsoft.Extensions.Options package version to 8.0.0. (#5051)
