Updated OpenTelemetry from 1.16.0 to 1.18.0.

Release notes

Sourced from OpenTelemetry's releases.

1.18.0

For highlights and announcements pertaining to this release see: Release Notes > 1.18.0.

The following changes are from the previous release 1.17.0.

  • NuGet: OpenTelemetry v1.18.0

    • Fixed self-diagnostics log lines being silently dropped when an event message or parameter contained enough 3-byte UTF-8 characters to overflow the internal buffer estimate. Such content is now truncated.
      (#​7543)

    • Fixed activity creation throwing when multiple tracer providers return a sampler attribute with the same key.
      (#​7558)

    • Added the otel.sdk.processor.log.processed SDK self-observability metric.
      (#​7486)

    • Added the otel.sdk.processor.span.processed SDK self-observability metric.
      (#​7598)

    • BatchActivityExportProcessor and SimpleActivityExportProcessor no longer forward spans to the exporter once Shutdown has been called, and BatchActivityExportProcessor.Shutdown now waits for in-flight OnEnd calls to finish enqueueing before flushing.
      (#​7598)

    • Fix logger, meter and tracer providers leaking background threads if an exception is thrown by their constructor after resource creation.
      (#​7615)

    • CircularBufferBuckets.Copy optimized to use bulk array copies.
      (#​7670)

    • Restored configured MaxScale after delta exponential histogram collection.
      (#​7671)

    See CHANGELOG for details.

  • NuGet: OpenTelemetry.Api v1.18.0

    • Avoid formatting exceptions and creating exception attributes when RecordException is called on a span that is not recorded.

    No notable changes.

    See CHANGELOG for details.

  • NuGet: OpenTelemetry.Exporter.Console v1.18.0

1.18.0-beta.1

The following changes are from the previous release 1.17.0-beta.1.

  • NuGet: OpenTelemetry.Exporter.Prometheus.AspNetCore v1.18.0-beta.1

    • Fix concurrent scrapes returning an empty response under contention. Now the exporter will return an HTTP 500 error instead.
      (#​7571)

    • Waiting for concurrent scrapes to finish before collecting no longer blocks, which could stall concurrent scrapes being waited on.
      (#​7571)

    • Fixed the interaction between PrometheusAspNetCoreOptions.TranslationStrategy and content negotiation. The configured strategy is now applied before content negotiation, instead of the negotiated escaping scheme replacing the strategy's, and the Content-Type header now reports the escaping scheme that was applied rather than the one that was negotiated.
      (#​7610)

    • Fixed metric values and histogram bucket bounds being written with 17 significant digits instead of their shortest round-trippable representation.
      (#​7589)

    • Fixed the canonical representation used for histogram le and summary quantile label values falling back to 17 significant digits incorrectly.
      (#​7589)

    • Fixed a race where a slow scrape could return an HTTP 200 instead of 408.
      (#​7615)

    • Updated OpenTelemetry core component version(s) to 1.18.0.
      (#​7674)

    See CHANGELOG for details.

  • NuGet: OpenTelemetry.Exporter.Prometheus.HttpListener v1.18.0-beta.1

    • Fix concurrent scrapes returning an empty response under contention. Now the exporter will return an HTTP 500 error instead.
      (#​7571)

    • Waiting for concurrent scrapes to finish before collecting no longer blocks, which could stall concurrent scrapes being waited on.
      (#​7571)

    • A scrape which is still collecting when the listener is disposed now returns an HTTP 503 response.
      (#​7587)

    • Shutting down the listener no longer waits indefinitely for its request processing loop to stop, and no longer throws if the loop faulted.
      (#​7587)

    • Fixed the interaction between PrometheusHttpListenerOptions.TranslationStrategy and content negotiation. The configured strategy is now applied before content negotiation, instead of the negotiated escaping scheme replacing the strategy's, and the Content-Type header now reports the escaping scheme that was applied rather than the one that was negotiated.
      (#​7610)

    • Fixed metric values and histogram bucket bounds being written with 17 significant digits instead of their shortest round-trippable representation.

      (#​7441)

    • Replaced the vendored copy of
      EnvironmentVariablesConfigurationProvider with a direct
      Microsoft.Extensions.Configuration.EnvironmentVariables package dependency.
      Consumers gain automatic pickup of upstream bug fixes and security patches;
      no public API or behavioural change.
      (#​7146)

    • Added a verbose OpenTelemetry-Sdk self-diagnostics event that is emitted
      when an activity is dropped because its local (in-process) parent is not
      recorded.
      (#​7427)

    • Added support for a Schema URL on Resource instances.

    • Fixed TraceContextPropagator to normalize empty tracestate header values
      to null when extracting trace context.
      (#​7407,
      #​7433)

    • The library is now marked as trim and AOT compatible.
      (#​7441)

    • Experimental (pre-release builds only): Updated EnvironmentVariableCarrier.Get

      (#​7441)

    • Fix double unit suffixes in metric names when using OpenMetrics.
      (#​7454)

    • Fix incorrect handling of leading digits in metric names for OpenMetrics.
      (#​7454)

    • Add PrometheusAspNetCoreOptions.ScopeInfoEnabled property to enable or
      disable scope labels in Prometheus metrics. Defaults to true.

1.18.0-beta.1

The following changes are from the previous release 1.17.0-beta.1.

  • NuGet: OpenTelemetry.Exporter.Prometheus.AspNetCore v1.18.0-beta.1

    • Fix concurrent scrapes returning an empty response under contention. Now the exporter will return an HTTP 500 error instead.
      (#​7571)

    • Waiting for concurrent scrapes to finish before collecting no longer blocks, which could stall concurrent scrapes being waited on.
      (#​7571)

    • Fixed the interaction between PrometheusAspNetCoreOptions.TranslationStrategy and content negotiation. The configured strategy is now applied before content negotiation, instead of the negotiated escaping scheme replacing the strategy's, and the Content-Type header now reports the escaping scheme that was applied rather than the one that was negotiated.
      (#​7610)

    • Fixed metric values and histogram bucket bounds being written with 17 significant digits instead of their shortest round-trippable representation.
      (#​7589)

    • Fixed the canonical representation used for histogram le and summary quantile label values falling back to 17 significant digits incorrectly.
      (#​7589)

    • Fixed a race where a slow scrape could return an HTTP 200 instead of 408.
      (#​7615)

    • Updated OpenTelemetry core component version(s) to 1.18.0.
      (#​7674)

    See CHANGELOG for details.

  • NuGet: OpenTelemetry.Exporter.Prometheus.HttpListener v1.18.0-beta.1

    • Fix concurrent scrapes returning an empty response under contention. Now the exporter will return an HTTP 500 error instead.
      (#​7571)

    • Waiting for concurrent scrapes to finish before collecting no longer blocks, which could stall concurrent scrapes being waited on.
      (#​7571)

    • A scrape which is still collecting when the listener is disposed now returns an HTTP 503 response.
      (#​7587)

    • Shutting down the listener no longer waits indefinitely for its request processing loop to stop, and no longer throws if the loop faulted.
      (#​7587)

    • Fixed the interaction between PrometheusHttpListenerOptions.TranslationStrategy and content negotiation. The configured strategy is now applied before content negotiation, instead of the negotiated escaping scheme replacing the strategy's, and the Content-Type header now reports the escaping scheme that was applied rather than the one that was negotiated.
      (#​7610)

    • Fixed metric values and histogram bucket bounds being written with 17 significant digits instead of their shortest round-trippable representation.
      (#​7589)

    • Fixed the canonical representation used for histogram le and summary quantile label values falling back to 17 significant digits incorrectly.

1.17.0-rc.1

The following changes are from the previous release 1.16.0.

  • NuGet: OpenTelemetry v1.17.0-rc.1

    • Fixed a metric point reclaim data race on CPU ARM architectures.
      (#​7401)

    • The library is now marked as trim and AOT compatible.
      (#​7441)

    • Replaced the vendored copy of
      EnvironmentVariablesConfigurationProvider with a direct
      Microsoft.Extensions.Configuration.EnvironmentVariables package dependency.
      Consumers gain automatic pickup of upstream bug fixes and security patches;
      no public API or behavioural change.
      (#​7146)

    • Added a verbose OpenTelemetry-Sdk self-diagnostics event that is emitted
      when an activity is dropped because its local (in-process) parent is not
      recorded.
      (#​7427)

    • Added support for a Schema URL on Resource instances.
      (#​7472)

    • Fixed a metric storage leak that occurred when meters and instruments were
      repeatedly created and disposed.
      (#​7466)

    • Added ExcludedTagKeys property to MetricStreamConfiguration to support
      excluding specific tag keys from metric streams.
      (#​7373)

    See CHANGELOG for details.

  • NuGet: OpenTelemetry.Api v1.17.0-rc.1

    • Fixed TraceContextPropagator to normalize empty tracestate header values
      to null when extracting trace context.
      (#​7407,
      #​7433)

    • The library is now marked as trim and AOT compatible.
      (#​7441)

    • Experimental (pre-release builds only): Updated EnvironmentVariableCarrier.Get
      to read only the normalized environment variable name, following the updated
      environment variable carrier specification.
      Non-normalized carrier keys are no longer matched, even when they would
      normalize to the requested key.

      (#​7429)

    • The library is now marked as trim and AOT compatible.
      (#​7441)

    • Fix double unit suffixes in metric names when using OpenMetrics.
      (#​7454)

    • Fix incorrect handling of leading digits in metric names for OpenMetrics.
      (#​7454)

    • Add PrometheusAspNetCoreOptions.ScopeInfoEnabled property to enable or
      disable scope labels in Prometheus metrics. Defaults to true.
      (#​7436)

      schemes when negotiated via the Accept header.
      (#​7439)

      when negotiated via the Accept header.
      (#​7440)

    • Add PrometheusAspNetCoreOptions.ResourceConstantLabels property to select
      resource attributes to add to each metric as constant labels. Defaults to
      null (no resource attributes are added as metric labels).
      (#​7471)

    • Add PrometheusAspNetCoreOptions.MaxScrapeResponseSizeBytes to configure
      the maximum size of a scrape response. The default is now ~166 MiB.
      (#​7487)

      limit now responds with HTTP 500.
      (#​7487)

    • Fixed the Prometheus text exposition format emitting redundant comments.
      (#​7491)

Updated OpenTelemetry.Instrumentation.AspNetCore from 1.15.2 to 1.18.0.

Release notes

Sourced from OpenTelemetry.Instrumentation.AspNetCore's releases.

1.18.0

1.18.0-rc.1

1.18.0-beta.2

1.18.0-beta.1

  • NuGet: OpenTelemetry.Exporter.Geneva v1.18.0-beta.1

    • Fixed a metric TLV serialization issue where an exemplar whose filtered tags
      serialized to more than 255 bytes caused the payload to be corrupted.
      (#​4856)

    • Renamed the PrivatePreviewEnableOtlpProtobufEncoding connection string switch
      to EnableOtlpProtobufEncoding. The old PrivatePreviewEnableOtlpProtobufEncoding
      switch is no longer supported.
      (#​4920)

    • Fixed a regression introduced in 1.17.0 where EtwDataTransport prepended a
      synthetic 4-byte length field to the ETW payload for logs and traces, causing
      the agent to reject the data with "Bad forward protocol format". The raw
      payload is once again written as a single unframed field.
      (#​4941)
