End User Changelog

🛑 Breaking changes 🛑

• componentstatus: Change the signature of the componentstatus.NewEvent to accept multiple options. (#13210) Changes the signature of the component.NewEvent to accept multiple EventBuilderOption, like the new WithAttributes constructor.

🚩 Deprecations 🚩

• service: move service.noopTraceProvider feature gate to deprecated stage (#13492) The functionality of the feature gate is available via configuration with the following telemetry settings: service: telemetry: traces: level: none

• mdatagen: Remove the deletion of generated_component_telemetry_test.go. (#12067) This file used to be generated by mdatagen. Starting with 0.122.0, the code deletes that file. It is no longer necessary to delete the file, as code has had time to upgrade to mdatagen and delete the file.

• service: The telemetry.disableHighCardinalityMetrics feature gate is deprecated (#13537) The feature gate is now deprecated since metric views can be configured. The feature gate will be removed in v0.134.0.

The metric attributes removed by this feature gate are no longer emitted by the Collector by default, but if needed, you can achieve the same functionality by configuring the following metric views:

yaml service: telemetry: metrics: level: detailed views: - selector: meter_name: "go.opentelemetry.io/contrib/instrumentation/google.golang.org/grpc/otelgrpc" stream: attribute_keys: excluded: ["net.sock.peer.addr", "net.sock.peer.port", "net.sock.peer.name"] - selector: meter_name: "go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp" stream: attribute_keys: excluded: ["net.host.name", "net.host.port"]

Note that this requires setting service::telemetry::metrics::level: detailed. If you have a strong use case for using views in combination with a different level, please show your interest in https://github.com/open-telemetry/opentelemetry-collector/issues/10769.

💡 Enhancements 💡

• pdata: Generate Logs/Traces/Metrics/Profiles and p[log|trace|metric|profile]ExportResponse with pdatagen. (#13597) This change brings consistency on how these structs are written and remove JSON marshaling/unmarshaling hand written logic.
• confighttp: Add option to configure ForceAttemptHTTP2 to support HTTP/1 specific transport settings. (#13426)
• pdata: Avoid unnecessary buffer copy when JSON marshal fails. (#13598)
• cmd/mdatagen: Use a custom host implementation for lifecycle tests (#13589) Use a custom noop host implementation that implements all non-deprecated, publicly-accessible interfaces implemented by the Collector service.
• processorhelper: Add processor internal duration metric. (#13231)
• pdata: Improve RemoveIf for slices to not reference anymore the removed memory (#13522)

🧰 Bug fixes 🧰

• pdata: Fix null pointer access when copying into a slice with larger cap but smaller len. (#13523)
• confighttp: Fix middleware configuration field name from "middleware" to "middlewares" for consistency with configgrpc (#13444)

• memorylimiterextension, memorylimiterprocessor: Memory limiter extension and processor shutdown don't throw an error if the component was not started first. (#9687) The components would throw an error if they were shut down before being started. With this change, they will no longer return an error, conforming to the lifecycle of components expected.

• confighttp: Reuse zstd Reader objects (#11824)

API Changelog

🛑 Breaking changes 🛑

• componenttest: Remove GetFactory from the host returned by NewNopHost (#13577) This method is no longer part of the component.Host interface.

💡 Enhancements 💡

• exporterhelper: Provide an interface queue_batch.Setting.MergeCtx so users can control how context values are preserved or combined (#13320) By supplying a custom mergeCtx function, users can control how context values are preserved or combined. The default behavior is to preserve no context values.

• pdata: Generate Logs/Traces/Metrics/Profiles and p[log|trace|metric|profile]ExportResponse with pdatagen. (#13597) This change brings consistency on how these structs are written and remove JSON marshaling/unmarshaling hand written logic.

• pdata: Avoid unnecessary buffer copy when JSON marshal fails. (#13598)
• pipeline: Mark module as stable (#12831)
