🛑 Breaking changes 🛑

  • processorhelper: Update incoming/outgoing metrics to a single metric with a otel.signal attributes. (#11144) The following metrics were added in the previous version

    • otelcol_processor_incoming_spans
    • otelcol_processor_outgoing_spans
    • otelcol_processor_incoming_metric_points
    • otelcol_processor_outgoing_metric_points
    • otelcol_processor_incoming_log_records
    • otelcol_processor_outgoing_log_records

    They are being replaced with the following to more closely align with OTEP 259:

    • otelcol_processor_incoming_items
    • otelcol_processor_outgoing_items

  • processorhelper: Remove deprecated [Traces|Metrics|Logs]Inserted funcs (#11151)

  • config: Mark UseLocalHostAsDefaultHostfeatureGate as stable (#11235)

🚩 Deprecations 🚩

  • processorhelper: deprecate accepted/refused/dropped metrics (#11201) The following metrics are being deprecated as they were only used in a single processor:
    • otelcol_processor_accepted_log_records
    • otelcol_processor_accepted_metric_points
    • otelcol_processor_accepted_spans
    • otelcol_processor_dropped_log_records
    • otelcol_processor_dropped_metric_points
    • otelcol_processor_dropped_spans
    • otelcol_processor_refused_log_records
    • otelcol_processor_refused_metric_points
    • otelcol_processor_refused_spans

💡 Enhancements 💡

  • pdata: Add support to MoveTo for Map, allow avoiding copies (#11175)
  • mdatagen: Add stability field to telemetry metrics, allowing the generated description to include a stability string. (#11160)
  • confignet: Mark module as Stable. (#9801)
  • confmap/provider/envprovider: Support default values when env var is empty (#5228)
  • mdatagen: mdatagen validateMetrics() support validate metrics in telemetry.metric (#10925)
  • service/telemetry: Mark useOtelWithSDKConfigurationForInternalTelemetry as stable (#7532)
  • mdatagen: Use cobra for the command, add version flag (#11196)

🧰 Bug fixes 🧰

  • service: Ensure process telemetry is registered when internal telemetry is configured with readers instead of an address. (#11093)

  • mdatagen: Fix incorrect generation of metric tests with boolean attributes. (#11169)

  • otelcol: Fix the Windows Event Log configuration when running the Collector as a Windows service. (#5297, #11051)

  • builder: Honor build_tags in config (#11156)

  • builder: Fix version for providers in the default config (#11123)

  • cmd/builder: Temporarily disable strict versioning checks (#11129, #11152) The strict versioning check may be enabled by default in a future version once all configuration providers are stabilized.

  • confmap: Fix loading config of a component from a different source. (#11154) This issue only affected loading the whole component config, loading parts of a component config from a different source was working correctly.

API Changes

🛑 Breaking changes 🛑

  • otlpexporter: The TimeoutSettings field in otlpexporter.Config was renamed to TimeoutConfig. (#11132)
  • connector: Change TracesRouterAndConsumer, NewTracesRouter, MetricsRouterAndConsumer, NewMetricsRouter, LogsRouterAndConsumer, and NewLogsRouter to use pipeline.ID instead of component.ID. (#11204)
  • extension: Remove deprecated extension interfaces. (#11043) They are now available in the extensioncapabilities module.

🚩 Deprecations 🚩

  • exporterhelper: Deprecate TimeoutSettings/QueueSettings in favor of TimeoutConfig/QueueConfig. (#6767)

  • configgrpc: Deprecate ClientConfig.ToClientConn/ServerConfig.ToServer in favor of ToClientConnWithOptions/ToServerWithOptions (#9480) Users providing a grpc.DialOption/grpc.ServerOption should now wrap them into a generic option with WithGrpcDialOption/WithGrpcServerOption.

  • componentprofiles: Deprecates DataTypeProfiles. Use SignalProfiles instead. (#11204)

  • componentstatus: Deprecates NewInstanceID, AllPipelineIDs, and WithPipelines. Use NewInstanceIDWithPipelineIDs, AllPipelineIDsWithPipelineIDs, and WithPipelineIDs instead. (#11204)

  • exporterqueue: Deprecates Settings.DataType. Use Settings.Signal instead. (#11204)

  • service: Deprecates pipelines.Config. Use pipelines.ConfigWithPipelineID instead. (#11204)

  • component: Deprecates DataType, DataTypeTraces, DataTypeMetrics, and DataTypeLogs. Use pipeline.Signal, SignalTraces, SignalMetrics, and SignalLogs instead. (#11204)

  • service: Deprecates service's implementation of GetExporters interface. Use GetExportersWithSignal instead. (#11249)

  • scraperhelper: Deprecate NewScraperWithComponentType, should use NewScraper (#11159)
