Updated OpenTelemetry from 1.10.0 to 1.15.0.

Release notes

Sourced from OpenTelemetry's releases.

1.15.0

For highlights and announcements pertaining to this release see: Release Notes > 1.15.0.

The following changes are from the previous release 1.14.0.

  • NuGet: OpenTelemetry v1.15.0

    • Added support for the OTEL_SDK_DISABLED environment variable in TracerProvider,
      MeterProvider, and LoggerProvider. When OTEL_SDK_DISABLED=true,
      the SDK returns no-op implementations for all telemetry signals.
      The OTEL_SDK_DISABLED environment variable is only evaluated upon application
      startup, later changes have no effect.
      (#​6568)

    • Added LowMemory temporality as an option in the OTLP metrics exporter.
      (#​6648)

    • Added support for Meter.TelemetrySchemaUrl property.
      (#​6714)

    • Improve performance and reduce memory consumption for metrics histograms.
      (#​6715)

    • Decode value in OTEL_RESOURCE_ATTRIBUTES environment variable.
      (#​6737)

    See CHANGELOG for details.

  • NuGet: OpenTelemetry.Api v1.15.0

    • Added a new overload for TracerProvider.GetTracer which accepts an optional
      string? schemaUrl parameter, allowing a schema URL to be set on the Tracer.
      (#​6736)

    See CHANGELOG for details.

  • NuGet: OpenTelemetry.Api.ProviderBuilderExtensions v1.15.0

1.13.1-beta.1

The following changes are from the previous release 1.13.0-beta.1.

1.13.0

For highlights and announcements pertaining to this release see: Release Notes > 1.13.0.

The following changes are from the previous release 1.12.0.

  • NuGet: OpenTelemetry v1.13.0

    • Added a verification to ensure that a MetricReader can only be registered
      to a single MeterProvider, as required by the OpenTelemetry specification.
      (#​6458)

    • Added FormatMessage configuration option to self-diagnostics feature. When
      set to true (default is false), log messages will be formatted by replacing
      placeholders with actual parameter values for improved readability.

      Example OTEL_DIAGNOSTICS.json:

      {
          "LogDirectory": ".",
          "FileSize": 32768,
          "LogLevel": "Warning",
          "FormatMessage": true
      }
    • Fixed parsing of OTEL_TRACES_SAMPLER_ARG decimal values to always use .
      as the delimiter when using the traceidratio sampler, preventing
      locale-specific parsing issues.
      (#​6444)

    See CHANGELOG for details.

  • NuGet: OpenTelemetry.Api v1.13.0

    • Added AddLink(SpanContext, SpanAttributes?) to TelemetrySpan to support
      linking spans and associating optional attributes for advanced trace relationships.
      (#​6305)

    • Experimental (only in pre-release versions): Added the EventName property
      to LogRecordData
      (#​6306)

    See CHANGELOG for details.

  • NuGet: OpenTelemetry.Api.ProviderBuilderExtensions v1.13.0
