End User Changelog

🛑 Breaking changes 🛑

• service: Lowercase values for 'otelcol.component.kind' attributes. (#12865)

• service: Restrict the telemetry.newPipelineTelemetry feature gate to metrics. (#12856, #12933)
  The "off" state of this feature gate introduced a regression, where the Collector's internal logs were missing component attributes. See issue #12870 for more details on this bug.

  On the other hand, the "on" state introduced an issue with the Collector's default internal metrics, because the Prometheus exporter does not currently support instrumentation scope attributes.

  To solve both of these issues, this change turns on the new scope attributes for logs and traces by default regardless of the feature gate.
  However, the new scope attributes for metrics stay locked behind the feature gate, and will remain off by default until the Prometheus exporter is updated to support scope attributes.

  Please understand that enabling the telemetry.newPipelineTelemetry feature gate may break the export of Collector metrics through, depending on your configuration.
  Having a batch processor in multiple pipelines is a known trigger for this.

  This comes with a breaking change, where internal logs exported through OTLP will now use instrumentation scope attributes to identify the source component instead of log attributes.
  This does not affect the Collector's stderr output. See the changelog for v0.123.0 for a more detailed description of the gate's effects.

💡 Enhancements 💡

• mdatagen: Add support for attributes for telemetry configuration in metadata. (#12919)
• configmiddleware: Add extensionmiddleware interface. (#12603, #9591)
• configgrpc: Add gRPC middleware support. (#12603, #9591)
• confighttp: Add HTTP middleware support. (#12603, #9591, #7441)

🧰 Bug fixes 🧰

• exporterhelper: Do not ignore the num_consumers setting when batching is enabled. (#12244)
• exporterhelper: Reject elements larger than the queue capacity (#12847)
• mdatagen: Add time and plog package imports (#12907)
• confmap: Maintain nil values when marshaling or unmarshaling nil slices (#11882)
  Previously, nil slices were converted to empty lists, which are semantically different
  than a nil slice. This change makes this conversion more consistent when encoding
  or decoding config, and these values are now maintained.

🐛 Known bugs 🐛

• service/telemetry: Missing attributes in internal Collector logs (#12870).
  • See issue description for workarounds.

🛑 Breaking changes 🛑

• service/telemetry: Mark telemetry.disableAddressFieldForInternalTelemetry as beta, usage of deprecated service::telemetry::address are ignored (#12756)
  To restore the previous behavior disable telemetry.disableAddressFieldForInternalTelemetry feature gate.
• exporterbatch: Remove deprecated fields min_size_items and max_size_items from batch config. (#12684)

🚩 Deprecations 🚩

• otlpexporter: Mark BatcherConfig as deprecated, use sending_queue::batch instead (#12726)
• exporterhelper: Deprecate blocking in favor of block_on_overflow. (#12710)
• exporterhelper: Deprecate configuring exporter batching separately. Use sending_queue::batch instead. (#12772)
  Moving the batching configuration to sending_queue::batch requires setting sending_queue::sizer to items
  which means that sending_queue::queue_size needs to be also increased by the average batch size number (roughly
  x5000 for the default batching configuration).
  See https://github.com/open-telemetry/opentelemetry-collector/tree/main/exporter/exporterhelper#configuration

💡 Enhancements 💡

• exporterhelper: Add support to configure batching in the sending queue. (#12746)

• exporterhelper: Add support for wait_for_result, remove disabled_queue (#12742)
  This has a side effect for users of the experimental BatchConfig with the queue disabled, since not this is | uses only NumCPU() consumers.

• exporterhelper: Allow exporter memory queue to use different type of sizers. (#12708)

• service: Add "telemetry.newPipelineTelemetry" feature gate to inject component-identifying attributes in internal telemetry (#12217)
  With the feature gate enabled, all internal telemetry (metrics/traces/logs) will include some of
  the following instrumentation scope attributes:

  • otelcol.component.kind
  • otelcol.component.id
  • otelcol.pipeline.id
  • otelcol.signal
  • otelcol.signal.output

  These attributes are defined in the Pipeline Component Telemetry RFC,
  and identify the component instance from which the telemetry originates.
  They are added automatically without changes to component code.

  These attributes were already included in internal logs as regular log attributes, starting from
  v0.120.0. For consistency with other signals, they have been switched to scope attributes (with
  the exception of logs emitted to standard output), and are now enabled by the feature gate.

  Please make sure that the exporter / backend endpoint you use has support for instrumentation
  scope attributes before using this feature. If the internal telemetry is exported to another
  Collector, a transform processor could be used to turn them into other kinds of attributes if
  necessary.

• exporterhelper: Enable support to do batching using bytes sizer (#12751)

• service: Add config key to set metric views used for internal telemetry (#10769)
  The service::telemetry::metrics::views config key can now be used to explicitly set the list of
  metric views used for internal telemetry, mirroring meter_provider::views in the SDK config.
  This can be used to disable specific internal metrics, among other uses.

  This key will cause an error if used alongside other features which would normally implicitly create views, such as:

  • not setting service::telemetry::metrics::level to detailed;
  • enabling the telemetry.disableHighCardinalityMetrics feature flag.

🛑 Breaking changes 🛑

• service: Batch processor telemetry is no longer emitted at "basic" verbosity level (#7890)
  According to the guidelines, basic-level telemetry should be reserved for core Collector APIs.
  Components such as the batch processor should emit telemetry starting from the "normal" level
  (which is also the default level).

  Migration: If your Collector telemetry was set to level: basic and you want to keep seeing
  batch processor-related metrics, consider switching to level: normal instead.

End User Changelog

💡 Enhancements 💡

• exporterhelper: Add blocking option to control queue behavior when full (#12090)
• debugexporter: Add EventName to debug exporter for Logs. EventName was added as top-level field in the LogRecord from 1.5.0 of proto definition. (#11966)
• confighttp: Added support for configuring compression levels. (#10467)
  A new configuration option called CompressionParams has been added to confighttp. | This allows users to configure the compression levels for the confighttp client.
• exporterhelper: Change the memory queue implementation to not pre-allocate capacity objects. (#12070)
  This change improves memory usage of the collector under low utilization and is a prerequisite for supporting different other size limitations (number of items, bytes).

🧰 Bug fixes 🧰

• mdatagen: apply fieldalignment to generated code (#12121)
• otelcoltest: Set DefaultScheme to env in the test ConfigProvider to replicate the default provider used by the Collector. (#12066)
