Description

Adds a tests: goleak: declaration to the filter package's metadata.yaml and the corresponding generated_package_test.go so that goroutine leaks are detected automatically on every test run. Follows the same pattern as open-telemetry#15632.

Testing

Ran go test ./... in filter/ — all tests pass with goleak enabled

…gen package targeting (open-telemetry#15453)  #### Description This change fixes mode detection for `-p` by resolving the target package's on-disk source directory via a lightweight `packages.Load` call before reading its `metadata.yaml`. This works for any package reachable from the local module graph, including cross-repo dependencies present in the module cache. When the package is not in the local module graph, detection falls back to the existing default; a new `-m component|package` flag is provided as a manual override for that case.  #### Testing Changes covered with unit tests.  #### Documentation Updated `README.md` .  #### Authorship - [x] I, a human, wrote this pull request description myself.

…dling (open-telemetry#15452)  #### Description PR provides fix for pattern propagation in schema resolver (when `-r` flag set) and improves overall error handling for better debugging.  #### Testing Unit tests updated. #### Authorship - [x] I, a human, wrote this pull request description myself.

#### Description This allows metadata to specify versioned metrics, which will allow migration to the latest semantic-conventions for collector components. For example, if a metric name remains the same but its type or attributes change, we can specify the latest versioned metric with '@'. For example ```yaml # Metric that keeps the same visible name but changes type (gauge -> sum) system.cpu.utilization: enabled: true description: CPU utilization as a ratio. stability: beta unit: "1" gauge: value_type: double migration: to: system.cpu.utilization@v1 through_gates: disable_old: receiver.hostmetrics.DontEmitV0SystemConventions enable_new: receiver.hostmetrics.EmitV1SystemConventions attributes: [cpu, state] system.cpu.utilization@v1: # Emit under the stable user-facing name enabled: true description: CPU utilization as a monotonic cumulative sum. stability: beta unit: "1" sum: value_type: double aggregation_temporality: cumulative monotonic: true attributes: [cpu.logical_number, state] ``` For same-name metrics, dual emission of both legacy and latest is not allowed, see RFC [here](https://github.com/open-telemetry/opentelemetry-collector/blob/main/docs/rfcs/semconv-feature-gates.md#handling-conflicts-during-double-publishing). There are two scenarios: - If the type differs (e.g., Gauge to Sum), only the latest metric is emitted with the new type. - If the attributes differ, only the latest metric is emitted, but with attributes from both legacy and latest versions. - For different-name metrics (e.g., linux.memory.available → system.memory.linux.available), both can be emitted during migration. ## Output ### Legacy and Latest Metric have the same name but its type and attributes differ #### metadata schema ```yaml type: cpu status: class: scraper stability: beta: [metrics] distributions: [core, contrib, k8s] codeowners: active: [dmitryax, braydonk, rogercoll] reaggregation_enabled: true sem_conv_version: 1.9.0 feature_gates: - id: receiver.hostmetrics.DontEmitV0SystemConventions description: When enabled, semconv legacy attributes are disabled. stage: alpha from_version: v0.145.0 reference_url: open-telemetry/opentelemetry-collector-contrib#45592 skip_strict_validation: true - id: receiver.hostmetrics.EmitV1SystemConventions description: When enabled, semconv stable attributes are enabled. stage: alpha from_version: v0.145.0 reference_url: open-telemetry/opentelemetry-collector-contrib#45592 skip_strict_validation: true attributes: cpu: description: Logical CPU number starting at 0. type: string requirement_level: recommended cpu.logical_number: description: The logical CPU number [0, n-1]. type: int state: description: Breakdown of CPU usage by type. type: string requirement_level: recommended enum: [idle, interrupt, nice, softirq, steal, system, user, wait] metrics: system.cpu.frequency: enabled: false description: Current frequency of the CPU core in Hz. unit: "Hz" stability: development gauge: value_type: double attributes: [cpu] migration: to: system.cpu.frequency@v1 through_gates: disable_old: receiver.hostmetrics.DontEmitV0SystemConventions enable_new: receiver.hostmetrics.EmitV1SystemConventions warnings: if_enabled_not_set: This metric will be disabled by default in a future release.

Add an opt-in configuration snapshot path for extensions that need more than the Collector's effective configuration. The new API exposes a single `ConfigSnapshot` abstraction instead of separate watcher APIs for each representation. Proposed solution for open-telemetry#15432. Related contrib use case: open-telemetry/opentelemetry-collector-contrib#44341 ### New public API surface - `confmap.(*Resolver).UnexpandedConf() *Conf`: returns the merged configuration captured by the most recent `Resolve` call before provider/env-var references were expanded. Returns nil if `Resolve` has not been called. - `extension/extensioncapabilities.ConfigSnapshot`: provides access to config representations. It currently exposes `Effective()` and `Unexpanded()`, and can grow with additional representations later without adding separate watcher interfaces. - `extension/extensioncapabilities.NewConfigSnapshot(effective, unexpanded *confmap.Conf) ConfigSnapshot`: creates a snapshot and returns owned `confmap.Conf` copies from its accessors. - `extension/extensioncapabilities.ConfigSnapshotWatcher`: optional extension interface notified through `NotifyConfigSnapshot(ctx, ConfigSnapshot)`. - `service.Settings.ConfigSnapshot`: optional field passed to config snapshot watchers during `Service.Start`. - `service/extensions.(*Extensions).NotifyConfigSnapshot(ctx, ConfigSnapshot) error`: invokes `NotifyConfigSnapshot` on registered extensions and falls back to deprecated `ConfigWatcher` for compatibility. ### Compatibility `extensioncapabilities.ConfigWatcher`, `service.Settings.CollectorConf`, and `service/extensions.(*Extensions).NotifyConfig` are deprecated, but existing effective-config watchers keep working. `otelcol.Collector` still sets `CollectorConf` when constructing `service.Settings`. The unexpanded config is redacted by mirroring the effective redacted config: `configopaque.String` values are redacted unless the entire original leaf is a provider reference such as `${env:TOKEN}`. #### Authorship - [x] I, a human, wrote this pull request description myself. --------- Co-authored-by: Pablo Baeyens <pbaeyens31+github@gmail.com> Co-authored-by: Evan Bradley <11745660+evan-bradley@users.noreply.github.com>

This aligns with Go's `net/http` behavior. Callers that relied on credentials being sent to a redirect target on another host will need to target that host directly.

…is false (open-telemetry#15443)  #### Description When `Enabled` is set to `false`, the `Validate()` method in `BackOffConfig` returned early without checking any field values. This meant invalid configurations (e.g. negative `InitialInterval`) would silently pass validation. Removed the early return so all fields are validated regardless of the `Enabled` flag.  #### Link to tracking issue Fixes open-telemetry#15437  #### Testing Updated `TestDisabledWithInvalidValues` to assert that errors are returned for invalid field values even when `Enabled=false`. Added `TestDisabledWithValidValues` to confirm a well-formed config with `Enabled=false` still passes.

Update otelbot token creation to use GitHub App client IDs. The app-id input for `actions/create-github-app-token` is deprecated in favor of client-id. The matching `OTELBOT_*_CLIENT_ID` organization variables have been provisioned, so this updates direct token creation from `app-id / *_APP_ID` to `client-id / *_CLIENT_ID`.

…lemetry#15558)  #### Description A regression where the zPages extension would have been broken was caught only incidentally by a builder integration test here: open-telemetry#15557. This adds a proper E2E test that verifies the service host implements the anonymous interface used by the zPages extension. We could break the interface into a package imported by each as well. I opted for the test instead just because I would rather not introduce a package for a minor one-off interface. But if that's the preferred approach I'm okay closing this and taking that route.  #### Authorship - [x] I, a human, wrote this pull request description myself.  --------- Co-authored-by: Pablo Baeyens <pbaeyens31+github@gmail.com> Co-authored-by: Alex Boten <223565+codeboten@users.noreply.github.com>

([#15386](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/15386)) When a server returns a 2xx status but the response body exceeds the 64kB read limit, the body is truncated and proto unmarshaling fails. Previously this was treated as a retryable error, causing duplicate data to be exported. Now it is marked as a permanent error so the retry logic will not re-send data that was already accepted by the server. - `pkg/config/configretry`: Always validate BackOffConfig fields regardless of the Enabled flag. ([#15437](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/15437)) - `pkg/service`: Ensure receivers always start after all other components ([#15495](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/15495)) There was previously a race condition where multiple receivers using a shared internal implementation, such as the OTLP receiver, could start sending telemetry into a pipeline before all its components had fully started. - `processor/memory_limiter`: Fix degenerate collector performance when exporter has problems causing permanent CPU-burning GC loop ([#4981](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/4981)) Forced GC runs now use exponential backoff when deemed ineffective (still above soft limit and less than 5% reclaimed) to avoid preventing recovery by overloading CPU with excessive GC runs. The cap on the backoff interval is exposed via `max_gc_interval_when_soft_limited` and `max_gc_interval_when_hard_limited` (both default `30s`); set either to `0` to disable backoff on that path. - `provider/env`: Fix empty env var default resolving to nil instead of empty string ([#14587](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/14587)) When using ${env:VAR:-} with an unset variable, the empty default now correctly resolves to an empty string instead of nil.  ### [`v0.155.0`](https://redirect.github.com/open-telemetry/opentelemetry-collector/blob/HEAD/CHANGELOG.md#v1610v01550) [Compare Source](https://redirect.github.com/open-telemetry/opentelemetry-collector/compare/v0.154.0...v0.155.0) ##### 🛑 Breaking changes 🛑 - `pkg/confighttp`: Remove stabilized gate `confighttp.framedSnappy` ([#15420](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/15420)) - `pkg/configoptional`: Remove stabilized gate `configoptional.AddEnabledField`. ([#15421](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/15421)) - `pkg/confmap`: Remove stabilized featuregate `confmap.newExpandedValueSanitizer` ([#15418](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/15418)) - `pkg/exporterhelper`: Remove stable gate `exporter.PersistRequestContext`. ([#15424](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/15424)) - `pkg/otelcol`: Remove stable gate `otelcol.printInitialConfig` ([#15425](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/15425)) - `pkg/service`: Remove stable featuregate `telemetry.UseLocalHostAsDefaultMetricsAddress` ([#15419](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/15419)) - `pkg/xpdata`: Remove stable gate `pdata.enableRefCounting`. ([#15426](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/15426)) - `processor/memory_limiter`: Rename deprecated memory limiter metrics to include the `memory_limiter` prefix (e.g. `otelcol_processor_memory_limiter_*`) to clarify they are specific to this processor. ([#11203](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/11203)) ##### 🚀 New components 🚀 - `cmd/schemagen`: Move the `schemagen` CLI from opentelemetry-collector-contrib to this repository as `cmd/schemagen`. ([#14543](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/14543)) The tool's source is identical to the upstream contrib version (github.com/open-telemetry/opentelemetry-collector-contrib/cmd/schemagen) except for the module path and the test fixtures' namespace, which now reflect the collector module (go.opentelemetry.io/collector/cmd/schemagen). A contrib-only integration test that pointed at three contrib components is removed; contrib's existing `make generate-schemas` + git-diff CI continues to exercise the FactoryMaps feature against real-world components. ##### 💡 Enhancements 💡 - `cmd/mdatagen`: Add support for versioned metrics ([#15309](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/15309)) Allows metadata to specify versioned metrics for migrating to new semantic conventions. There are two scenarios catered for when the metric name stays the same during migration. When a metric name stays the same but its type differs, just the latest metric is emitted with the new type. When a metric name stays the same but its attributes differ, the latest version is emitted with combined attributes during the migration period. - `cmd/schemagen`: Add `overlayFile` support to deep-merge hand-curated schema fragments into generated schemas. ([#14543](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/14543)) Components can declare an `overlayFile` in `.schemagen.yaml` pointing to a YAML file whose keys are recursively merged into the auto-generated schema after generation. This allows injecting descriptions, constraints, or additional properties that cannot be derived from Go types. Originally added to the contrib copy of `cmd/schemagen` in [open-telemetry/opentelemetry-collector-contrib#48917](https://redirect.github.com/open-telemetry/opentelemetry-collector-contrib/issues/48917) and brought over with the tool in this move. - `cmd/schemagen`: Add `-p` flag to specify a custom Go package pattern for the config struct. ([#14543](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/14543)) The new `-p` flag lets callers override the default `.` package pattern with an arbitrary Go package selector (e.g. a sub-package whose `Config` type schemagen should walk). Originally added to the contrib copy of `cmd/schemagen` in [open-telemetry/opentelemetry-collector-contrib#48966](https://redirect.github.com/open-telemetry/opentelemetry-collector-contrib/issues/48966) and brought over with the tool in this move. ##### 🧰 Bug fixes 🧰 - `cmd/mdatagen`: Fix an issue when the last feature gate is removed, stale files are left. ([#15423](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/15423)) - `cmd/mdatagen`: Fix known acronyms at the end of generated Go identifiers to be all-caps, same as in any other position ([#15438](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/15438)) - `cmd/schemagen`: Fix mode detection when using `-p` to target a package outside the current directory. ([#15453](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/15453)) A new `-m component|package` flag is available as a manual override when auto-detection is not possible.  ### [`v0.154.0`](https://redirect.github.com/open-telemetry/opentelemetry-collector/blob/HEAD/CHANGELOG.md#v1600v01540) [Compare Source](https://redirect.github.com/open-telemetry/opentelemetry-collector/compare/v0.153.0...v0.154.0) ##### 🛑 Breaking changes 🛑 - `cmd/builder`: The `--skip-get-modules` flag will no longer regenerate your `go.mod` file. ([#15390](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/15390)) This is mostly a bug fix, as it led to adverse behaviour that was unintended in the described flow in the README. Now when you run `--skip-get-modules`, your `go.mod` file will truly be untouched by `ocb` as the info log claims. ##### 💡 Enhancements 💡 - `pkg/config/configtls`: Add `include_insecure_cipher_suites` to configtls to enable insecure cipher suites. Insecure cipher suites are disabled by default for security. ([#13829](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/13829)) - `pkg/confighttp`: Add `ExposedHeaders` field to `CORSConfig` to allow setting the `Access-Control-Expose-Headers` response header. ([#15119](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/15119)) ##### 🧰 Bug fixes 🧰 - `cmd/mdatagen`: Removes the extra line in the README.md between status and description ([#15306](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/15306)) - `pkg/exporterhelper`: Fix nil-pointer panic in `sending_queue::batch` Unmarshal when `sending_queue::sizer` is set and `sending_queue::batch::enabled` is false. ([#14687](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/14687)) When `sending_queue::sizer` was set and `sending_queue::batch::enabled: false` cleared the batch Optional to None, the sizer-inheritance branch in `queuebatch.Config.Unmarshal` dereferenced a nil Optional and crashed the collector at startup. The branch now also requires `Batch.HasValue()`.  ### [`v0.153.0`](https://redirect.github.com/open-telemetry/opentelemetry-collector/blob/HEAD/CHANGELOG.md#v1590v01530) [Compare Source](https://redirect.github.com/open-telemetry/opentelemetry-collector/compare/v0.152.1...v0.153.0) ##### 🛑 Breaking changes 🛑 - `pkg/configoptional`: Stabilize feature gate configoptional.AddEnabledField ([#15333](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/15333)) - `pkg/confmap`: Stabilize confmap.newExpandedValueSanitizer feature gate ([#15339](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/15339)) - `pkg/exporterhelper`: mark exporter.PersistRequestContext as stable ([#15330](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/15330)) - `pkg/otelcol`: Stabilize otelcol.printInitialConfig gate ([#15340](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/15340)) - `pkg/pdata`: Remove pdata.useCustomProtoEncoding feature gate ([#15332](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/15332)) - `pkg/service`: Stabilize telemetry.UseLocalHostAsDefaultMetricsAddress gate ([#15342](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/15342)) - `pkg/xpdata`: Stabilize pdata.enableRefCounting feature gate ([#15331](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/15331)) ##### 🧰 Bug fixes 🧰 - `pkg/config/configgrpc`: Fix memory corruption and fatal error in Snappy ([#15237](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/15237), [#15320](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/15320))  ### [`v0.152.1`](https://redirect.github.com/open-telemetry/opentelemetry-collector/releases/tag/v0.152.1): v1.58.0/v0.152.1 [Compare Source](https://redirect.github.com/open-telemetry/opentelemetry-collector/compare/v0.152.0...v0.152.1) ##### Images and binaries here: <https://github.com/open-telemetry/opentelemetry-collector-releases/releases/tag/v0.152.1> #### End User Changelog ##### 💡 Enhancements 💡 - `pkg/exporterhelper`: Add `otelcol_exporter_in_flight_requests` metric to track the number of export requests currently in-flight per exporter. ([#15009](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/15009)) This UpDownCounter increments in startOp and decrements in endOp, allowing operators to monitor concurrent export activity and detect when an exporter is saturating its worker pool. ##### 🧰 Bug fixes 🧰 - `pkg/confighttp`: Close the original request body after reading block-format `Content-Encoding: snappy` requests. ([#15262](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/15262)) - `pkg/confighttp`: Recover from panics in decompression libraries, return HTTP 400 instead of 500. ([#13228](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/13228)) - `pkg/confighttp`: Enforce `max_request_body_size` on `Content-Encoding: snappy` requests before the decoded buffer is allocated. ([#15252](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/15252)) - `pkg/otelcol`: Stop emitting verbose gRPC transport messages at WARN during normal client disconnect. ([#5169](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/5169)) grpc-go gates chatty per-RPC notices (e.g. "HandleStreams failed to read frame: connection reset by peer") behind `LoggerV2.V(2)`. zapgrpc.Logger.V conflates grpclog verbosity with zap severity, so V(2) returns true whenever WARN is enabled and these messages emit at WARN. Wrap the installed grpclog.LoggerV2 with a corrected V() that compares against a fixed verbosity threshold, matching grpclog's intended semantics. See [uber-go/zap#1544](https://redirect.github.com/uber-go/zap/issues/1544). - `pkg/pdata`: `pcommon.Value.AsString` no longer HTML-escapes `<`, `>`, and `&` inside `ValueTypeMap` and `ValueTypeSlice` values, matching the behavior already used for `ValueTypeStr`. ([#14662](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/14662)) - `pkg/service`: Fix Prometheus config defaults mismatch when host is explicitly set in telemetry configuration. ([#13867](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/13867)) When users explicitly configured the telemetry metrics section (e.g. to change the host), the Prometheus exporter boolean fields (WithoutScopeInfo, WithoutUnits, WithoutTypeSuffix) defaulted to nil/false instead of true, causing metric name format changes compared to the implicit default configuration. This fix applies the correct defaults during config unmarshaling. - `pkg/service`: Return noop tracer provider when no trace processors are defined ([#15135](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/15135))  #### API Changelog ##### 🚩 Deprecations 🚩 - `pkg/xconfmap`: Deprecate `xconfmap.Validator` and `confmap.Validate` in favor of `confmap.Validator` and `confmap.Validate`. ([#15142](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/15142)) ##### 💡 Enhancements 💡 - `cmd/mdatagen`: Add `go_struct.ignore_default` flag to suppress default value generation for individual config fields. ([#15156](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/15156)) Setting `go_struct.ignore_default: true` on a config field causes mdatagen to omit that field's default from the generated `createDefaultConfig` function, emitting `nil` for pointer fields and `configoptional.None` for optional fields. - `pkg/confmap`: Add the `confmap.Validator` interface and `confmap.Validate` function for configuration validation. ([#15142](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/15142)) Config structs should generally implement the interface to provide validation of their fields. The `confmap.Validate` function can be used to validate config structs in testing, but is only meant to be called at runtime by the Collector itself. ##### 🧰 Bug fixes 🧰 - `pkg/pdata`: `pcommon.Value.AsString` no longer HTML-escapes `<`, `>`, and `&` inside `ValueTypeMap` and `ValueTypeSlice` values, matching the behavior already used for `ValueTypeStr`.

([#15097](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/15097)) We expect that this will not break existing use-cases where the generated collector is only used in an interim manner for builds. It enables the possibility of tracking the generated Collector code as a longer living artifact, allowing it to be run on any machine (whereas absolute paths will be different depending on the machine the Collector source is generated on.) We have added `dist::use_absolute_replace_paths` to go back to the absolute path behaviour in the case where there is an unforeseen use-case that requires absolute paths. - `pkg/confighttp`: Stabilize framedSnappy feature gate. ([#15096](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/15096)) ##### 💡 Enhancements 💡 - `all`: Add declarative schema support for service telemetry resource configuration. ([#14411](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/14411)) The `service::telemetry::resource` configuration now accepts the declarative schema with explicit name/value pairs: ```yaml service: telemetry: resource: schema_url: https://opentelemetry.io/schemas/1.38.0 attributes: - name: service.name value: my-collector - name: host.name value: collector-host ``` The legacy inline attribute map format is still supported for backward compatibility: ```yaml service: telemetry: resource: service.name: my-collector host.name: collector-host ``` Note: `resource.detectors` is accepted for forward compatibility but is not yet applied by the collector. - `exporter/otlp_grpc`: Added the `server.address` and `url.path` attributes to metrics generated by the otlp exporter. ([#14998](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/14998)) - `exporter/otlp_http`: Added the `server.address` and `url.path` attributes to metrics generated by the otlp\_http exporter. ([#14998](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/14998)) - `pkg/config/configgrpc`: Add `UserAgent` field to `ClientConfig` to allow overriding the default gRPC user-agent string. ([#14686](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/14686)) The otlp gRPC exporter was unconditionally setting the User-Agent via grpc.WithUserAgent() at dial time, which takes precedence over per-call metadata, causing any user-configured User-Agent to be silently discarded. A dedicated `UserAgent` field has been added to `ClientConfig` which, when set, is used in the dial option directly instead of the default BuildInfo-derived string. - `pkg/config/configgrpc`: Accept gRPC resolver scheme URIs in client endpoint (e.g. passthrough:///host:port) to allow control over name resolution ([#14990](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/14990)) After the migration to grpc.NewClient, some gRPC client components such as the OTLP exporter experienced connection issues in dual-stack DNS environments. This can now be fixed by using the passthrough:/// gRPC resolver scheme in the endpoint field. - `pkg/config/confignet`: Add support for Windows Named Pipe (npipe) transport ([#15085](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/15085)) - `pkg/service`: Emit a warning when using the old v0.2.0 declarative config format ([#15088](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/15088)) ##### 🧰 Bug fixes 🧰 - `pkg/otelcol`: Print components exactly once in the `otelcol components` command ([#14682](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/14682)) This resolves an issue where aliased components were skipped. - `pkg/otelcol`: Synchronize Collector Run and Shutdown lifecycles so that Shutdown blocks until Run completes all cleanup. ([#4947](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/4947)) Shutdown now blocks until Run finishes cleanup, matching http.Server semantics.

By introducing a new MarshalOption to disable redaction directly at the confmap encoding level, the unredacted mode now preserves all component defaults natively without requiring post-processing. - `pkg/service`: Headers on the internal telemetry OTLP exporter are now redacted when the configuration is marshaled ([#14756](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/14756))  ### [`v0.149.0`](https://redirect.github.com/open-telemetry/opentelemetry-collector/blob/HEAD/CHANGELOG.md#v1550v01490) [Compare Source](https://redirect.github.com/open-telemetry/opentelemetry-collector/compare/v0.148.0...v0.149.0) ##### 🛑 Breaking changes 🛑 - `pkg/service`: Remove `service_name`, `service_instance_id`, and `service_version` as constant labels on every internal metric datapoint. These attributes are already present in `target_info` and were being duplicated on each series for OpenCensus backwards compatibility. ([#14811](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/14811)) Previously, the collector stamped every internal metric series (e.g. `otelcol_process_runtime_heap_alloc_bytes`) with `service_name`, `service_instance_id`, and `service_version` labels to match the old OpenCensus behavior. These attributes are now only present in the `target_info` metric, which is the correct Prometheus/OTel convention. Users who filter or group by these labels on individual metrics will need to update their queries to use `target_info` joins instead. ##### 💡 Enhancements 💡 - `all`: Move aix/ppc64 to tier 3 support ([#13380](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/13380)) - `all`: Upgrade the profiles stability status to alpha ([#14817](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/14817)) The following components have their profiles status upgraded from development to alpha: - pdata/pprofile - connector/forward - exporter/debug - receiver/nop - exporter/nop - exporter/otlp\_grpc - exporter/otlp\_http - `cmd/mdatagen`: Add semconv reference for attributes ([#13297](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/13297)) ##### 🧰 Bug fixes 🧰 - `cmd/mdatagen`: Fix entity code generation so `extra_attributes` are emitted as resource attributes instead of entity descriptive attributes.

Users scraping this endpoint with the Prometheus receiver will see these renamed labels in resource and datapoint attributes. As a workaround, add the following `metric_relabel_configs` to your scrape config in prometheus receiver: ```yaml metric_relabel_configs: - source_labels: [service_name] target_label: service.name - source_labels: [service_instance_id] target_label: service.instance.id - source_labels: [service_version] target_label: service.version - regex: service_name|service_instance_id|service_version action: labeldrop ``` See [#14814](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/14814) for details and updates. ##### 🛑 Breaking changes 🛑 - `all`: Change metric units to be singular to match OTel specification, e.g. `{requests}` -> `{request}` ([#14753](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/14753)) ##### 💡 Enhancements 💡 - `cmd/mdatagen`: Add deprecated\_type field to allow specifying an alias for component types.

([#14663](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/14663)) When the sending queue and retry are disabled, calling ConsumeTraces, ConsumeMetrics, ConsumeLogs, or ConsumeProfiles before the OTLP exporter initializes its gRPC clients could cause a nil pointer dereference panic. The push methods now return an error instead of panicking. - `exporter/otlp_http`: Show the actual destination URL in error messages when request URL is modified by middleware. ([#14673](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/14673)) Unwraps the `*url.Error` returned by `http.Client.Do()` to prevent misleading error logs when a middleware extension dynamically updates the endpoint. - `pdata/pprofile`: Switch the dictionary of dictionary tables entries only once when merging profiles ([#14709](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/14709)) For dictionary table data, we used to switch their dictionaries when doing the switch for the data that uses them. However, when an entry is associated with multiple other data (several samples can use the same stack), we would have been switching the dictionaries of the entry multiple times. We now switch dictionaries for dictionary table data only once, before switching the resource profiles.  ### [`v0.147.0`](https://redirect.github.com/open-telemetry/opentelemetry-collector/blob/HEAD/CHANGELOG.md#v1530v01470) [Compare Source](https://redirect.github.com/open-telemetry/opentelemetry-collector/compare/v0.146.1...v0.147.0) ##### 💡 Enhancements 💡 - `exporter/debug`: Output bucket counts for exponential histogram data points in normal verbosity. ([#10463](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/10463)) - `pkg/exporterhelper`: Add `metadata_keys` configuration to `sending_queue.batch.partition` to partition batches by client metadata ([#14139](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/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](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/14436)) - `cmd/mdatagen`: Fix duplicate error output when CLI command execution fails in the mdatagen tool.

([#14634](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/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](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/14634)) - `pkg/config/configmiddleware`: Add context.Context to HTTP middleware interface constructors. ([#14523](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/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](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/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](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/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](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/14491)) - `pkg/scraperhelper`: Log scrapers now emit log-appropriate receiver telemetry ([#14654](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/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.

([#13956](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/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](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/14530)) The new `init` subcommand initializes a new custom collector - `cmd/builder`: Add "telemetry" field to allow configuring telemetry providers ([#14575](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/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](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/14113)) - `cmd/mdatagen`: Add optional `relationships` field to entity schema in metadata.yaml ([#14284](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/14284)) - `exporter/debug`: Add `output_paths` configuration option to control output destination when `use_internal_logger` is false. ([#10472](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/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](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/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.

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](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/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](https://redirect.github.com/open-telemetry/opentelemetry-collector/issues/14307))  ### [`v0.144.0`](https://redirect.github.com/open-telemetry/opentelemetry-collector/blob/HEAD/CHANGELOG.md#v1500v01440) [Compare Source](https://redirect.github.com/open-telemetry/opentelemetry-collector/compare/v0.143.0...v0.144.0) ##### 🛑 Breaking changes 🛑 - `pkg/exporterhelper`: Change verbosity level for otelcol\_exporter\_queue\_batch\_send\_size metric to detailed.

…d `service.partialReloadReceivers` (open-telemetry#15397) #### Description Phase 1 implementation of the [Partial Reload RFC](https://github.com/open-telemetry/opentelemetry-collector/blob/main/docs/rfcs/partial-reload.md), receivers only. This adds the `service.partialReload` alpha feature flag (disabled by default) and the `service.partialReloadReceivers` beta feature flag (enabled by default). This allows the overall feature to be enabled with `service.partialReload`, and as different phases occur it allows the ability to disable an individual phase if it becomes problem in the overall partial reload system.  #### Testing - `otelcol/config_diff_test.go` - tests covering receiversOnlyChange scenarios (identical configs, receiver-only changes, processor/exporter/connector/extension/telemetry/pipeline changes, connector-as-receiver changes) - `service/internal/graph/graph_test.go`.`UpdateReceivers` - add receiver, remove receiver, config change rebuild, no-op, pipeline set change, simultaneous add/remove/rebuild, connector-as-receiver untouched, nil host guard - `otelcol/collector_test.go`.`TestCollectorPartialReceiverReload` - verifies end-to-end that with the feature gate enabled, a receiver-only config change triggers partial reload (stays in StateRunning, logs partial reload message, never logs full restart) - `otelcol/collector_test.go` - add benchmark tests for add, remove, update a receiver  #### Documentation Added documentation on how configuration reload works. Added documentation on how configuration reload works when the `service.receiverPartialReload` feature flag is enabled. #### Authorship - [x] I, a human, wrote this pull request description myself.

…lued attribute (open-telemetry#15572)  #### Description Enabling the `process` resource detector (or any detector emitting a slice-valued resource attribute) aborts collector startup with `<Invalid value type []string>`. `createResource` fed the OTel SDK attribute value directly into `pcommon.Value.FromRaw`, which only accepts `[]any` for slices — typed scalar slices (`[]string`/`[]int64`/`[]float64`/`[]bool`) hit the `default` error branch and abort `service.New`. This converts slice-typed SDK attributes element-wise into a `pcommon` slice, mirroring the existing `ToZapFields` SDK-attribute converter (`internal/telemetry/attribute.go`, which type-switches on `attribute.Value.Type()`). Scalar and other types keep the existing `FromRaw` path. The `pcommon.FromRaw`/`AsRaw` `[]any`-symmetric contract (PR open-telemetry#6579) is intentional, so the fix is caller-side rather than in pdata.  #### Link to tracking issue Fixes open-telemetry#15571  #### Testing Added a `TestCreateResource` subtest exercising the `process` detector; it asserts the collector resource is built and `process.command_args` is a proper element-wise slice equal to `os.Args` (not a stringified `"[...]"`). Red before the fix (`<Invalid value type []string>`), green after. Full `service/telemetry/otelconftelemetry` module passes with `-race`.  #### Documentation No changes.  #### Authorship - [x] I, a human, wrote this pull request description myself.  --------- Signed-off-by: Pavel Lazureykis <pavel@lazureykis.dev>

…#15557)  #### Description The host passed to extensions currently doesn't implement `componentstatus.Reporter` and therefore all calls to `componentstatus.ReportStatus` inside extensions [are ignored](https://github.com/open-telemetry/opentelemetry-collector/blob/d1d8e8ddb283e89ddce0059715dceda5265224c7/component/componentstatus/status.go#L191), preventing them from reporting their own status. This wraps the host so the host given to extensions is suitable for reporting status events.  #### Link to tracking issue Relates to open-telemetry/opentelemetry-collector-contrib#48758.  #### Testing Ran a manual test with a modified zPages extension.  #### Authorship - [x] I, a human, wrote this pull request description myself.

#### Description Running [the "Inform Incompatible PRs" CI](https://github.com/open-telemetry/opentelemetry-collector/blob/main/.github/workflows/api-compatibility.yml) locally, it seems it only checks for API breakage for the packages inside the root module. This PR rewrites the relevant Makefiles to actually check all non-internal packages inside all stable Collector modules, and updates the CI check to match. #### Testing I briefly tested the `make` commands on open-telemetry#15589, confirming that the expected breaking change is now correctly flagged. #### Authorship - [x] I, a human, wrote this pull request description myself.

…en-telemetry#15514)  #### Description Adds first-class extended type aliases to cmd/mdatagen, so `metadata.yaml` authors can write a Go-idiomatic type name directly as the type field of a config property, instead of combining `type` + `format` or `type` + `x-customType` by hand.  #### Link to tracking issue Fixes open-telemetry#15513  #### Testing - Sample components extended with examples - Changes covered with unit tests  #### Documentation Extended README of mdatagen with info about usage of extended types and how to add new.  #### Authorship - [x] I, a human, wrote this pull request description myself.

Adds a `tests: goleak:` declaration to the filter package's metadata.yaml and the corresponding generated_package_test.go so that goroutine leaks are detected automatically on every test run. Follows the same pattern used in config/configtls (PR open-telemetry#15632). Assisted-by: Claude Sonnet 4.6
