Bump OpenTelemetry.Instrumentation.AspNetCore from 1.6.0 to 1.8.1

[dependabot]

Updated OpenTelemetry.Instrumentation.AspNetCore from 1.6.0 to 1.8.1.

Release notes

Sourced from OpenTelemetry.Instrumentation.AspNetCore's releases.

1.8.1

OpenTelemetry.Instrumentation.AspNetCore

• 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 tag. For example,
  ?key1=value1&key2=value2 becomes ?key1=Redacted&key2=Redacted. You can
  disable this redaction by setting the environment variable
  OTEL_DOTNET_EXPERIMENTAL_ASPNETCORE_DISABLE_URL_QUERY_REDACTION to true.
  (#​5532)

1.8.0

If you're interested in knowing all of the changes that went into 1.8.0 release, please go through the release notes of all the previous pre-release versions for 1.8.0:

• https://github.com/open-telemetry/opentelemetry-dotnet/releases/tag/core-1.8.0-beta.1
• https://github.com/open-telemetry/opentelemetry-dotnet/releases/tag/core-1.8.0-rc.1

Changes in 1.8.0:

OpenTelemetry.Exporter.Console

• Added support for ActivitySource.Version property.
  (#​5472)

OpenTelemetry.Exporter.OpenTelemetryProtocol

• OtlpExporter will no longer throw an exception (even on .NET Core 3.1)
  when the System.Net.Http.SocketsHttpHandler.Http2UnencryptedSupport
AppContext switch is NOT set AND using OtlpExportProtocol.Grpc
  to send to an insecure ("http") endpoint.
  System.Net.Http.SocketsHttpHandler.Http2UnencryptedSupport
  is not required to be set when using .NET 5 or newer.
  (#​5486)

• Replaced environment variable
  OTEL_DOTNET_EXPERIMENTAL_OTLP_ENABLE_INMEMORY_RETRY with
  OTEL_DOTNET_EXPERIMENTAL_OTLP_RETRY. OTEL_DOTNET_EXPERIMENTAL_OTLP_RETRY
  when set to in_memory will enable automatic retries in case of transient
  failures during data export to an OTLP endpoint.
  (#​5495)

1.8.0-rc.1

OpenTelemetry

• TracerProviders can now have a sampler configured via the
  OTEL_TRACES_SAMPLER environment variable. The supported values are:
  always_off, always_on, traceidratio, parentbased_always_on,
  parentbased_always_off, and parentbased_traceidratio. The options
  traceidratio and parentbased_traceidratio may have the sampler probability
  configured via the OTEL_TRACES_SAMPLER_ARG environment variable.
  For details see: OpenTelemetry Environment Variable
  Specification.
  (#​5448)

OpenTelemetry.Exporter.Prometheus.AspNetCore

• Fix serializing scope_info when buffer overflows
  (#​5407)

• Add target_info to Prometheus exporters when using OpenMetrics
  (#​5407)

OpenTelemetry.Exporter.Prometheus.HttpListener

• Fix serializing scope_info when buffer overflows
  (#​5407)

• Add target_info to Prometheus exporters when using OpenMetrics
  (#​5407)

OpenTelemetry.Exporter.Zipkin

• Zipkin tags used for Instrumentation Library changed from otel.library.name and
  otel.library.version to otel.scope.name and otel.scope.version respectively.
  Old versions of attributes are deprecated, but still exported
  for backward compatibility.
  (#​5473)

1.8.0-beta.1

OpenTelemetry

• Throw NotSupportedException when using SetErrorStatusOnException method for Tracing in Mono Runtime and Native AOT environment because the dependent Marshal.GetExceptionPointers() API is not supported on these platforms. (#​5374)

• Fixed an issue where LogRecord.Attributes (or LogRecord.StateValues alias) could become out of sync with LogRecord.State if either is set directly via the public setters. This was done to further mitigate issues introduced in 1.5.0 causing attributes added using custom processor(s) to be missing after upgrading. For details see:(#​5169)

• Fixed an issue where SimpleExemplarReservoir was not resetting internal state for cumulative temporality. (#​5230)

• Fixed an issue causing LogRecords to be incorrectly reused when wrapping an instance of BatchLogRecordExportProcessor inside another
  BaseProcessor<LogRecord> which leads to missing or incorrect data during export. (#​5255)

• Experimental (pre-release builds only): Added support for setting CardinalityLimit (the maximum number of data points allowed for a metric) when configuring a view (applies to individual metrics) and obsoleted MeterProviderBuilderExtensions.SetMaxMetricPointsPerMetricStream (previously applied to all metrics). The default cardinality limit for metrics remains at 2000. (#​5312, #​5328)

• Updated LogRecord to keep CategoryName and Logger in sync when using the experimental Log Bridge API. #​5317

• Added OpenTelemetryBuilderSdkExtensions class which contains extension methods (ConfigureResource, WithMetrics, WithTracing, and experimental WithLogging) for the IOpenTelemetryBuilder interface. (#​5265)

• Added Microsoft.Extensions.Diagnostics.Abstractions dependency so that the IOpenTelemetryBuilder.WithMetrics extension method can configure IMetricsListener. (#​5265)

• Experimental (pre-release builds only): The Exemplar.FilteredTags property now returns a ReadOnlyFilteredTagCollection instance and the Exemplar.LongValue property has been added. The MetricPoint.GetExemplars method has been replaced by MetricPoint.TryGetExemplars which outputs a ReadOnlyExemplarCollection instance. These are breaking changes for metrics exporters which support exemplars. (#​5386)

• Experimental (pre-release builds only): Added support for exemplars when using Base2 Exponential Bucket Histogram Aggregation configured via the View API. (#​5396)

• Experimental (pre-release builds only): Removed the ExemplarFilter, AlwaysOffExemplarFilter, AlwaysOnExemplarFilter, and TraceBasedExemplarFilter APIs. The MeterProviderBuilder.SetExemplarFilter extension method now accepts an ExemplarFilterType enumeration (which contains definitions for the supported filter types AlwaysOff, AlwaysOn, and TraceBased) instead of an ExemplarFilter instance. This was done in response to changes made to the OpenTelemetry Metrics SDK Specification. (#​5404)

• Experimental (pre-release builds only): The ExemplarFilter used by SDK MeterProviders can now be controlled via the OTEL_METRICS_EXEMPLAR_FILTER environment variable. The supported values are: always_off, always_on, and trace_based. For details see: OpenTelemetry Environment Variable Specification. (#​5412)

OpenTelemetry.Api.ProviderBuilderExtensions

• Added IOpenTelemetryBuilder interface to support authoring extensions which can configure multiple OpenTelemetry signals (tracing, metrics, and/or logs). (#​5265)

OpenTelemetry.Exporter.OpenTelemetryProtocol

• Experimental (pre-release builds only): Added LoggerProviderBuilder.AddOtlpExporter registration extensions. #​5103

• Removed the OTEL_DOTNET_EXPERIMENTAL_OTLP_EMIT_EXCEPTION_LOG_ATTRIBUTES environment variable, following the stabilization of the exception attributes exception.type, exception.message, and exception.stacktrace in the OpenTelemetry Semantic Conventions. These attributes, corresponding to LogRecord.Exception, are now stable and will be automatically included in exports. (#​5258)

• Updated OtlpLogExporter to set body on the data model from LogRecord.Body if {OriginalFormat} attribute is NOT found and FormattedMessage is null. This is typically the case when using the
  experimental Logs Bridge API. (#​5268)

• Updated OtlpLogExporter to set instrumentation scope name on the data model from LogRecord.Logger.Name if LogRecord.CategoryName is null. This is typically the case when using the experimental Logs Bridge API. (#​5300)

• URL encoded values in OTEL_EXPORTER_OTLP_HEADERS are now correctly decoded as it is mandated by the specification. (#​5316)

• Experimental (pre-release builds only): Add support in OtlpMetricExporter for emitting exemplars supplied on Counters, Gauges, and
  ExponentialHistograms. (#​5397)

• Setting Endpoint or HttpClientFactory properties on OtlpExporterOptions to null will now result in an ArgumentNullException being thrown. (#​5434)

• Introduced experimental support for automatically retrying export to the otlp endpoint when transient network errors occur. Users can enable this feature by setting OTEL_DOTNET_EXPERIMENTAL_OTLP_ENABLE_INMEMORY_RETRY environment variable to true. (#​5435)
  ... (truncated)

1.7.1

1.7.1 (stable instrumentation)

OpenTelemetry.Instrumentation.AspNetCore

• Fixed issue #​4466 where the activity instance returned by Activity.Current was different than instance obtained from IHttpActivityFeature.Activity. (#​5136)
• Fixed an issue where the http.route attribute was not set on either the Activity or http.server.request.duration metric generated from a request when an exception handling middleware is invoked. One caveat is that this fix does not address the problem for the http.server.request.duration metric when running ASP.NET Core 8. ASP.NET Core 8 contains an equivalent fix which should ship in version 8.0.2 (see: dotnet/aspnetcore#​52652). (#​5135)
• Fixes scenario when the net6.0 target of this library is loaded into a .NET 7+ process and the instrumentation does not behave as expected. This is an unusual scenario that does not affect users consuming this package normally. This fix is primarily to support the opentelemetry-dotnet-instrumentation project. (#​5252)

OpenTelemetry.Instrumentation.Http

• .NET Framework - fix description for http.client.request.duration metric. (#​5234)

1.7.0-beta.1 (pre-release instrumentation)

OpenTelemetry.Instrumentation.SqlClient

• Removed support for the OTEL_SEMCONV_STABILITY_OPT_IN environment variable which toggled the use of the new conventions for the server, client, and shared network attributes. Now that this suite of attributes are stable, this instrumentation will only emit the new attributes. (#​5270)
• Breaking Change: Renamed SqlClientInstrumentationOptions to SqlClientTraceInstrumentationOptions. (#​5285)
• Breaking Change: Stop emitting db.statement_type attribute. This attribute was never a part of the semantic conventions. (#​5301)

OpenTelemetry.Instrumentation.GrpcNetClient

• Breaking Change: Please be advised that the SuppressDownstreamInstrumentation option no longer works when used in conjunction with the OpenTelemetry.Instrumentation.Http package version 1.6.0 or greater. This is not a result of a change in the OpenTelemetry.Instrumentation.GrpcNetClient package therefore this also affects versions prior to this release. See this issue for details and workaround.
• Removed support for the OTEL_SEMCONV_STABILITY_OPT_IN environment variable which toggled the use of the new conventions for the server, client, and shared network attributes. Now that this suite of attributes are stable, this instrumentation will only emit the new attributes. (#​5259)
• Breaking Change: Renamed GrpcClientInstrumentationOptions to GrpcClientTraceInstrumentationOptions. (#​5272)

1.7.0

1.7.0 release for core components

If you're interested in knowing all of the changes that went into 1.7.0 release, please go through the Release notes of all the previous pre-release versions for 1.7.0.

1.7.0-beta.1 release for non-core components

Note: Instrumentation libraries were not included for 1.7.0-beta.1.

OpenTelemetry.Shims.OpenTracing

• Remove obsolete TracerShim(Tracer, TextMapPropagator) constructor. Use TracerShim(TracerProvider) or TracerShim(TracerProvider, TextMapPropagator) constructors. (#​4862)

1.7.0-rc.1

OpenTelemetry

• The AddService ResourceBuilder extension method will now generate the same service.instance.id for the lifetime of a process when autoGenerateServiceInstanceId is true. (#​4988)

• Fixed a Metrics SDK bug which led to ExemplarReservoir.Offer always being called regardless of whether or not the ExemplarFilter sampled the measurement. (#​5004) (#​5016)

• Update Metrics SDK to override the default histogram buckets for the followingmetrics from ASP.NET Core and HttpClient runtime:

  • signalr.server.connection.duration
  • kestrel.connection.duration
  • http.client.connection.duration

  These histogram metrics which have their Unit as s (second) will have their default histogram buckets as [ 0.01, 0.02, 0.05, 0.1, 0.2, 0.5, 1, 2, 5, 10, 30, 60, 120, 300 ]. (#​5008) (#​5021)

• Remove the bucket with value 0 for histogram buckets for all metrics from ASP.NET Core and HttpClient. (#​5021)

• Updated Microsoft.Extensions.Logging.Configuration package version to 8.0.0. (#​5051)

• Updated Microsoft.Extensions.Logging package version to 8.0.0. (#​5051)

• Revert the default behavior of Metrics SDK for Delta aggregation. It would not reclaim unused Metric Points by default. You can enable the SDK to reclaim unused Metric Points by setting the environment variable OTEL_DOTNET_EXPERIMENTAL_METRICS_RECLAIM_UNUSED_METRIC_POINTS to true before setting up the MeterProvider. (#​5052)

• Update Metrics SDK to override the default histogram buckets for ASP.NET (.NET Framework).

  Histogram metrics for the meter name OpenTelemetry.Instrumentation.AspNet and instrument name http.request.server.duration which have their Unit as s (second) will have their default histogram buckets as [ 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 ]. (#​5063)

• Added AddProcessor overload on OpenTelemetryLoggerOptions which exposes the factory pattern (Func<IServiceProvider, BaseProcessor<LogRecord>> implementationFactory). (#​4916)

• Add support for Instrumentation Scope Attributes (i.e Meter Tags), fixing issue #​4563. (#​5089)

• Added the ILoggingBuilder.UseOpenTelemetry experimental API extension for registering OpenTelemetry ILogger integration using LoggerProviderBuilder which supports the full DI (IServiceCollection \ IServiceProvider) API surface (mirrors tracing & metrics). (#​5072)

• Changed the ILoggingBuilder registration extensions (AddOpenTelemetry & UseOpenTelemetry) to fire the optional OpenTelemetryLoggerOptions configuration delegate AFTER the "Logging:OpenTelemetry" IConfiguration section has been applied. (#​5072)

OpenTelemetry.Api

• Updated System.Diagnostics.DiagnosticSource package version to 8.0.0. (#​5051)

OpenTelemetry.Api.ProviderBuilderExtensions

• Updated Microsoft.Extensions.DependencyInjection.Abstractions package version to 8.0.0. (#​5051)

OpenTelemetry.Exporter.Console

• Add support for Instrumentation Scope Attributes (i.e Meter Tags), fixing issue #​4563. (#​5089)

OpenTelemetry.Exporter.OpenTelemetryProtocol

• Made OpenTelemetry.Exporter.OtlpLogExporter public. (#​4979)

• Updated the OpenTelemetryLoggerOptions.AddOtlpExporter extension to retrieve OtlpExporterOptions and LogRecordExportProcessorOptions using the IServiceProvider / Options API so that they can be controlled via IConfiguration (similar to metrics and traces). (#​4916)
  ... (truncated)

1.7.0-alpha.1

OpenTelemetry

• Update AggregatorStore to reclaim unused MetricPoints for Delta aggregation temporality. (#​4486)

• Fixed a bug where TracerProviderBuilderBase was not invoking the instrumentationFactory delegate passed to the protected
AddInstrumentation method. (#​4873)

• Allowed metric instrument names to contain / characters. (#​4882)

• Breaking Change [Tracer|Meter|Logger]ProviderBuilder.Build extension will now throw a NotSupportedException if invoked on a non-SDK builder type. Previously it would return null. (#​4885)

• Updated Microsoft.Extensions.Logging package version to 8.0.0-rc.1.23419.4. (#​4920, #​4933)

OpenTelemetry.Api

• Fixed a bug which caused Tracer.StartRootSpan to generate a child span if a trace was running (Activity.Current != null). (#​4890)

• Added a Tracer cache inside of TracerProvider to prevent repeated calls to GetTracer from leaking memory. (#​4906)

• Fix TraceContextPropagator by validating the first digit of the hex-encoded trace-flags field of the traceparent header. (#​4893)

OpenTelemetry.Exporter.OpenTelemetryProtocol

• Bumped the version of Google.Protobuf used by the project to 3.22.5 so that consuming applications can be published as NativeAOT successfully. Also, a new performance feature can be used instead of reflection emit, which is not AOT-compatible. Removed the dependency on System.Reflection.Emit.Lightweight. (#​4859)

• Added support for OTEL_LOGRECORD_ATTRIBUTE_VALUE_LENGTH_LIMIT and OTEL_LOGRECORD_ATTRIBUTE_COUNT_LIMIT. (#​4887)

• Added ability to export attributes corresponding to LogRecord.Exception i.e. exception.type, exception.message and exception.stacktrace. These attributes will be exported when OTEL_DOTNET_EXPERIMENTAL_OTLP_EMIT_EXCEPTION_LOG_ATTRIBUTES environment variable will be set to true.

  NOTE: These attributes were removed in 1.6.0-rc.1 release in order to support stable release of OTLP Log Exporter. The attributes will now be available via environment variable mentioned above. (#​4892)

• Added ability to export attributes corresponding to LogRecord.EventId.Id as logrecord.event.id and LogRecord.EventId.Name as logrecord.event.name. The attributes will be exported when OTEL_DOTNET_EXPERIMENTAL_OTLP_EMIT_EVENT_LOG_ATTRIBUTES will be set to true.

  NOTE: These attributes were removed in 1.6.0-rc.1 release in order to support stable release of OTLP Log Exporter. The attributes will now be available via environment variable mentioned above. (#​4925)

• LogRecord.CategoryName will now be exported as InstrumentationScope name field under ScopeLogs. (#​4941)

OpenTelemetry.Exporter.Prometheus.AspNetCore

• Fixed writing boolean values to use the JSON representation (#​4823)

OpenTelemetry.Exporter.Prometheus.HttpListener

• Fixed writing boolean values to use the JSON representation (#​4823)

OpenTelemetry.Extensions.Hosting

• Changed the behavior of the OpenTelemetryBuilder.AddOpenTelemetry extension to INSERT OpenTelemetry services at the beginning of the IServiceCollection in an attempt to provide a better experience for end users capturing telemetry in hosted services. Note that this does not guarantee that OpenTelemetry services will be initialized while other hosted services start, so it is possible to miss telemetry until OpenTelemetry services are fully initialized.
