OpenTelemetry - CNCF/opentelemetry-java: Release v1.15.0

Name: opentelemetry-java

Owner: OpenTelemetry - CNCF

Release: Version 1.15.0

Released: 2022-06-10

License: Apache-2.0

Release Assets:

API

  • Add batch callback API, allowing a single callback to record measurements to multiple metric instruments.

SDK

Metrics

  • SdkMeterProvider#toString() now returns a useful string describing configuration.
  • Fix bug preventing proper function of Metrics SDK when multiple readers are present (#4436).
  • Fix reporting intervals for metrics for delta readers (#4400).

Exporter

  • BREAKING: merge all stable OTLP exporters into opentelemetry-exporter-otlp. opentelemetry-exporter-otlp-trace, opentelemetry-exporter-otlp-metrics, opentelemetry-exporter-otlp-http-trace, and opentelemetry-exporter-otlp-http-metrics are no longer published and their contents have been merged into a single artifact.
  • BREAKING: merge log OTLP exporters into opentelemetry-exporter-otlp-logs. opentelemetry-exporter-otlp-http-logs is no longer published and its contents have been merged into a single artifact.
  • Upgrade to OTLP protobuf version 0.18.0.
  • RetryInterceptor retries on SocketTimeoutException with no message.
  • Added JaegerGrpcSpanExporterBuilder#setMeterProvider(), enabling support of experimental jaeger span export metrics.
  • DEPRECATION: the opentelemetry-exporter-jaeger-proto module containing jaeger proto definitions and corresponding generated classes is deprecated for removal in next major version.
  • OTLP gRPC exporters support overriding :authority via OtlpGrpc*ExporterBuilder#addHeader("host", "my-authority-override").

SDK Extensions

  • BREAKING: Move ConfigureableMetricExporterProvider from opentelemetry-sdk-extension-autoconfigure to stable opentelemetry-sdk-extension-autoconfigure-spi.
  • Autoconfigure now supports multiple values for otel.metrics.exporter.
  • Autoconfigure now supports general attribute limits, applicable to span attributes, span event attributes, span link attributes, and log attributes.
  • Autoconfigure now supports an experimental option to disable the SDK. If otel.experimental.sdk.enabled=true, AutoConfiguredOpenTelemetrySdk#getOpenTelemetrySdk() returns a minimal (but not noop) OpenTelemetrySdk. The same minimal instance is set to GlobalOpenTelemetry.
  • New "get or default" methods have been added to ConfigProperties. E.g. ConfigProperties#getString("otel.metrics.exporter", "otlp") fetches the value for the property otel.metrics.exporter and returns otlp if it is not set.
  • Fix bug in ContainerResource provider that caused it to throw an exception in some instances when containerd is used.

Micrometer shim

  • Cache descriptions such that metrics with the same name use the first seen description.
