Updated OpenTelemetry.Exporter.Console from 1.17.0 to 1.18.0.

Release notes

Sourced from OpenTelemetry.Exporter.Console'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 1.18.0-rc.1.

  • 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.
      (#​7669)

    See CHANGELOG for details.

  • NuGet: OpenTelemetry.Api.ProviderBuilderExtensions v1.18.0

    No notable changes.

    See CHANGELOG for details.

  • NuGet: OpenTelemetry.Exporter.Console v1.18.0

    • Added support for serializing attribute values that are key/value lists (IEnumerable<KeyValuePair<string, object?>>). These attributes will be serialized as JSON objects.
      (#​7015)

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)
