Changelog

Unreleased

1.11.0-beta.1

Released 2025-Jan-27

  • The http.server.request.duration histogram (measured in seconds) produced by the metrics instrumentation in this package now uses the Advice API to set default explicit buckets following the OpenTelemetry Specification. (#2430)

  • Updated OpenTelemetry core component version(s) to 1.11.1. (#2477)

1.10.0-beta.1

Released 2024-Dec-09

  • Updated registration extension code to retrieve environment variables through IConfiguration. (#1976)

  • Updated OpenTelemetry core component version(s) to 1.10.0. (#2317)

  • Fixed an issue in ASP.NET instrumentation where route extraction failed for attribute-based routing with multiple HTTP methods sharing the same route template. (#2250)

1.9.0-beta.1

Released 2024-Jun-18

1.8.0-beta.3

Released 2024-May-23

  • Breaking change The Enrich callback option has been removed. For better usability, it has been replaced by three separate options: EnrichWithHttpRequest, EnrichWithHttpResponse and EnrichWithException. Previously, the single Enrich callback required the consumer to detect which event triggered the callback to be invoked (e.g., request start, response end, or an exception) and then cast the object received to the appropriate type: HttpRequest, HttpResponse, or Exception. The separate callbacks make it clear what event triggers them and there is no longer the need to cast the argument to the expected type. (#1824)

1.8.0-beta.2

Released 2024-Apr-17

  • Breaking Change: Fixed tracing instrumentation so that by default any values detected in the query string component of requests are replaced with the text Redacted when building the url.query attribute. For example, ?key1=value1&key2=value2 becomes ?key1=Redacted&key2=Redacted. You can disable this redaction by setting the environment variable OTEL_DOTNET_EXPERIMENTAL_ASPNET_DISABLE_URL_QUERY_REDACTION to true. (#1656)

1.8.0-beta.1

Released 2024-Apr-05

  • Breaking Change: Renamed AspNetInstrumentationOptions to AspNetTraceInstrumentationOptions. (#1604)

  • Breaking Change: server.address and server.port no longer added for http.server.request.duration metric. (#1606)

  • Breaking change Spans names and attributes will be set as per HTTP semantic convention v1.24.0:

    • span names follows: {HTTP method} [route name if available] pattern
    • error.type added when exception occurred while processing request,
    • http.request.method replaces http.method,
    • http.request.method_original added when http.request.method is not in canonical form,
    • http.response.status_code replaces http.status_code,
    • network.protocol.version added with HTTP version value,
    • server.address and server.port replace http.host,
    • url.path replaces http.target,
    • url.query added when query url part is not empty,
    • url.scheme added with http or https value,
    • user_agent.original replaces http.user_agent. (#1607)

  • ActivitySource.Version is set to NuGet package version. (#1624)

1.7.0-beta.2

Released 2024-Feb-07

  • Fix description for http.server.request.duration metric. (#1538)

1.7.0-beta.1

Released 2023-Dec-20

  • Added enrich functionality to metric instrumentation (#1407).

    • New overload of AddAspNetInstrumentation now accepts a configuration delegate.
    • The Enrich can be used to add additional metric attributes.

  • BREAKING: HTTP server metrics now follow stable semantic conventions (#1429).

    • New metric: http.server.request.duration
      • Unit: s (seconds)
      • Histogram Buckets: 0.005, 0.01, 0.025, 0.05, 0.075, 0.1, 0.25, 0.5, 0.75, 1, 2.5, 5, 7.5, 10
    • Old metric: http.server.duration
      • Unit: ms (milliseconds)
      • Histogram Buckets: 0, 5, 10, 25, 50, 75, 100, 250, 500, 750, 1000, 2500, 5000, 7500, 10000

    Note that the bucket changes are part of the 1.7.0-rc.1 release of the OpenTelemetry SDK.

    The following metric attributes has been added:

    • http.request.method (previously http.method)
    • http.response.status_code (previously http.status_code)
    • url.scheme (previously http.scheme)
    • server.address
    • server.port
    • network.protocol.version (1.1, 2, 3)
    • http.route

1.6.0-beta.2
