…ocessortest to v0.147.0 (#38) This PR contains the following updates: | Package | Change | [Age](https://docs.renovatebot.com/merge-confidence/) | [Confidence](https://docs.renovatebot.com/merge-confidence/) | |---|---|---|---| | [go.opentelemetry.io/collector/processor/processortest](https://github.com/open-telemetry/opentelemetry-collector) | `v0.144.0` → `v0.147.0` |  |  | --- ### Release Notes <details> <summary>open-telemetry/opentelemetry-collector (go.opentelemetry.io/collector/processor/processortest)</summary> ### [`v0.147.0`](https://github.com/open-telemetry/opentelemetry-collector/blob/HEAD/CHANGELOG.md#v1530v01470) [Compare Source](open-telemetry/opentelemetry-collector@v0.146.1...v0.147.0) ##### 💡 Enhancements 💡 - `exporter/debug`: Output bucket counts for exponential histogram data points in normal verbosity. ([#​10463](open-telemetry/opentelemetry-collector#10463)) - `pkg/exporterhelper`: Add `metadata_keys` configuration to `sending_queue.batch.partition` to partition batches by client metadata ([#​14139](open-telemetry/opentelemetry-collector#14139)) The `metadata_keys` configuration option is now available in the `sending_queue.batch.partition` section for all exporters. When specified, batches are partitioned based on the values of the listed metadata keys, allowing separate batching per metadata partition. This feature is automatically configured when using `exporterhelper.WithQueue()`. ##### 🧰 Bug fixes 🧰 - `cmd/builder`: Fix duplicate error output when CLI command execution fails in the builder tool. ([#​14436](open-telemetry/opentelemetry-collector#14436)) - `cmd/mdatagen`: Fix duplicate error output when CLI command execution fails in the mdatagen tool. ([#​14436](open-telemetry/opentelemetry-collector#14436)) - `cmd/mdatagen`: Fix semconv URL validation for metrics with underscores in their names ([#​14583](open-telemetry/opentelemetry-collector#14583)) Metrics like `system.disk.io_time` now correctly validate against semantic convention URLs containing underscores in the anchor tag. - `extension/memory_limiter`: Use ChainUnaryInterceptor instead of UnaryInterceptor to allow multiple interceptors. ([#​14634](open-telemetry/opentelemetry-collector#14634)) If multiple extensions that use the UnaryInterceptor are set the binary panics at start time. - `extension/memory_limiter`: Add support for streaming services. ([#​14634](open-telemetry/opentelemetry-collector#14634)) - `pkg/config/configmiddleware`: Add context.Context to HTTP middleware interface constructors. ([#​14523](open-telemetry/opentelemetry-collector#14523)) This is a breaking API change for components that implement or use extensionmiddleware. - `pkg/confmap`: Fix another issue where configs could fail to decode when using interpolated values in string fields. ([#​14034](open-telemetry/opentelemetry-collector#14034)) For example, a resource attribute can be set via an environment variable to a string that is parseable as a number, e.g. `1234`. (A similar bug was fixed in a previous release: that one was triggered when the field was nested in a struct, whereas this one is triggered when the field internally has type "pointer to string" rather than "string".) - `pkg/otelcol`: The featuregate subcommand now rejects extra positional arguments instead of silently ignoring them. ([#​14554](open-telemetry/opentelemetry-collector#14554)) - `pkg/queuebatch`: Fix data race in partition\_batcher where resetTimer() was called outside mutex, causing concurrent timer.Reset() calls and unpredictable batch flush timing under load. ([#​14491](open-telemetry/opentelemetry-collector#14491)) - `pkg/scraperhelper`: Log scrapers now emit log-appropriate receiver telemetry ([#​14654](open-telemetry/opentelemetry-collector#14654)) Log scrapers previously emitted the same receiver telemetry as metric scrapers, such as the otelcol\_receiver\_accepted\_metric\_points metric (instead of otelcol\_receiver\_accepted\_log\_records), or spans named receiver/myreceiver/MetricsReceived (instead of receiver/myreceiver/LogsReceived). This did not affect scraper-specific spans and metrics. - `processor/batch`: Fixes a bug where the batch processor would not copy `SchemaUrl` metadata from resource and scope containers during partial batch splits. ([#​12279](open-telemetry/opentelemetry-collector#12279), [#​14620](open-telemetry/opentelemetry-collector#14620)) <!-- previous-version --> ### [`v0.146.1`](https://github.com/open-telemetry/opentelemetry-collector/blob/HEAD/CHANGELOG.md#v1520v01461) [Compare Source](open-telemetry/opentelemetry-collector@v0.146.0...v0.146.1) <!-- previous-version --> ### [`v0.146.0`](https://github.com/open-telemetry/opentelemetry-collector/blob/HEAD/CHANGELOG.md#v01460) [Compare Source](open-telemetry/opentelemetry-collector@v0.145.0...v0.146.0) ##### 🛑 Breaking changes 🛑 - `all`: Increase minimum Go version to 1.25 ([#​14567](open-telemetry/opentelemetry-collector#14567)) ##### 🚩 Deprecations 🚩 - `pdata/pprofile`: Declare removed aggregation elements as deprecated. ([#​14528](open-telemetry/opentelemetry-collector#14528)) ##### 💡 Enhancements 💡 - `all`: Add detailed failure attributes to exporter send\_failed metrics at detailed telemetry level. ([#​13956](open-telemetry/opentelemetry-collector#13956)) The `otelcol_exporter_send_failed_{spans,metric_points,log_records}` metrics now include failure attributes when telemetry level is Detailed: `error.type` (OpenTelemetry semantic convention describing the error class) and `error.permanent` (indicates if error is permanent/non-retryable). The `error.type` attribute captures gRPC status codes (e.g., "Unavailable", "ResourceExhausted"), standard Go context errors (e.g., "canceled", "deadline\_exceeded"), and collector-specific errors (e.g., "shutdown"). This enables better alerting and debugging by providing standardized error classification. - `cmd/builder`: Introduce new experimental `init` subcommand ([#​14530](open-telemetry/opentelemetry-collector#14530)) The new `init` subcommand initializes a new custom collector - `cmd/builder`: Add "telemetry" field to allow configuring telemetry providers ([#​14575](open-telemetry/opentelemetry-collector#14575)) Most users should not need to use this, this field should only be set if you intend to provide your own OpenTelemetry SDK. - `cmd/mdatagen`: Introduce additional metadata (the version since the deprecation started, and the deprecation reason) for deprecated metrics. ([#​14113](open-telemetry/opentelemetry-collector#14113)) - `cmd/mdatagen`: Add optional `relationships` field to entity schema in metadata.yaml ([#​14284](open-telemetry/opentelemetry-collector#14284)) - `exporter/debug`: Add `output_paths` configuration option to control output destination when `use_internal_logger` is false. ([#​10472](open-telemetry/opentelemetry-collector#10472)) When `use_internal_logger` is set to `false`, the debug exporter now supports configuring the output destination via the `output_paths` option. This allows users to send debug exporter output to `stdout`, `stderr`, or a file path. The default value is `["stdout"]` to maintain backward compatibility. - `pkg/confmap`: Add experimental `ToStringMapRaw` function to decode `confmap.Conf` into a string map without losing internal types ([#​14480](open-telemetry/opentelemetry-collector#14480)) This method exposes the internal structure of a `confmap.Conf` which may change at any time without prior notice ##### 🧰 Bug fixes 🧰 - `cmd/mdatagen`: Reset aggDataPoints during metric init to avoid index out of range panic across emit cycles when reaggregation is enabled. ([#​14569](open-telemetry/opentelemetry-collector#14569)) - `cmd/mdatagen`: Fix panic when mdatagen is run without arguments. ([#​14506](open-telemetry/opentelemetry-collector#14506)) - `pdata/pprofile`: Fix off-by-one issue in dictionary lookups. ([#​14534](open-telemetry/opentelemetry-collector#14534)) - `pkg/config/confighttp`: Fix high cardinality span name from request method from confighttp server internal telemetry ([#​14516](open-telemetry/opentelemetry-collector#14516)) Follow spec to bound request method cardinality. - `pkg/otelcol`: Ignore component aliases in the `otelcol components` command ([#​14492](open-telemetry/opentelemetry-collector#14492)) - `pkg/otelcol`: Order providers and converters in alphabetical order in the `components` subcommand.

([#​14090](open-telemetry/opentelemetry-collector#14090)) - `pkg/config/configoptional`: Fix `Unmarshal` methods not being called when config is wrapped inside `Optional` ([#​14500](open-telemetry/opentelemetry-collector#14500)) This bug notably manifested in the fact that the `sending_queue::batch::sizer` config for exporters stopped defaulting to `sending_queue::sizer`, which sometimes caused the wrong units to be used when configuring `sending_queue::batch::min_size` and `max_size`. As part of the fix, `xconfmap` exposes a new `xconfmap.WithForceUnmarshaler` option, to be used in the `Unmarshal` methods of wrapper types like `configoptional.Optional` to make sure the `Unmarshal` method of the inner type is called. The default behavior remains that calling `conf.Unmarshal` on the `confmap.Conf` passed as argument to an `Unmarshal` method will skip any top-level `Unmarshal` methods to avoid infinite recursion in standard use cases. - `pkg/confmap`: Fix an issue where configs could fail to decode when using interpolated values in string fields. ([#​14413](open-telemetry/opentelemetry-collector#14413)) For example, a header can be set via an environment variable to a string that is parseable as a number, e.g. `1234` - `pkg/service`: Don't error on startup when process metrics are enabled on unsupported OSes (e.g. AIX) ([#​14307](open-telemetry/opentelemetry-collector#14307)) <!-- previous-version --> </details> --- ### Configuration 📅 **Schedule**: Branch creation - At any time (no schedule defined), Automerge - At any time (no schedule defined). 🚦 **Automerge**: Disabled by config.

Description
Allows configuring a custom telemetry provider module, whose factory will set in the
otelcol.Factoriesfield.Link to tracking issue
Assists with #14542.
Testing
I added basic tests to confirm the functionality of the field and did some manual testing on a Collector compiled to a Wasm binary to confirm that a no-op telemetry provider cuts down on space.
Documentation
Added to the docs and made some slight touchups. The docs could use some work, but that should be addressed separately.
