Pull request overview

Adds experimental self-observability (SDK exporter metrics) to the stdoutlog exporter, gated behind the OTEL_GO_X_OBSERVABILITY feature flag, following the project’s exporter-observability direction from issue #7020.

Changes:

Generate and add an internal counter package to provide unique exporter IDs (and allow deterministic resets in tests).
Wire stdoutlog.Exporter to initialize observability instrumentation and record inflight/exported/duration metrics during Export.
Add observability-focused tests and a benchmark for enabled vs disabled overhead.

… clarity

…is true Previously, the error.type attribute was only added when exportedLogsEnable was true. If opDurationEnable was true but exportedLogsEnable was false, the error attribute was never recorded. Now the condition is expanded to (exportedLogsEnable || opDurationEnable), while still only calling e.inst.exported.Add when exportedLogsEnable is true.

…at/yumosx/inst-stdlog

Previously, stdoutlog.New returned (nil, err) when self-observability setup failed, making the exporter unusable. This differed from stdouttrace.New and stdoutmetric.New, which return the exporter alongside the error, allowing core export functionality to continue even when experimental observability fails. Change stdoutlog.New to return the exporter with inst=nil and the instrumentation error separately, matching the behavior of the other stdout exporters. The Export method already guards against nil inst, so this is safe. Fixes the inconsistency where enabling observability could prevent stdout log export from working.

@flc1125 can you help review it?

The observ package uses semconv v1.41.0, but the test was importing v1.40.0, causing SchemaURL mismatch failures in TestObservability. Updates the test imports to match the actual package version.

(#8350) - Generate explicit histogram bucket boundaries from weaver configuration for HTTP and RPC duration instruments in `go.opentelemetry.io/otel/semconv/v1.41.0`. (#8002) ### Changed - ⚠️ **Breaking Change:** `go.opentelemetry.io/otel/sdk/metric` now applies a default cardinality limit of 2000 to comply with the Metrics SDK specification recommendation. New attribute sets are dropped when the cardinality limit is reached. The measurement of these sets are aggregated into a special attribute set containing `attribute.Bool("otel.metric.overflow", true)`. This can break users who relied on the previous unlimited default. Set `WithCardinalityLimit(0)` or the deprecated `OTEL_GO_X_CARDINALITY_LIMIT=0` environment variable to preserve unlimited cardinality. Note that support for `OTEL_GO_X_CARDINALITY_LIMIT` may be removed in a future release. (#8247) - `ErrorType` in `go.opentelemetry.io/otel/semconv` now unwraps errors created with `fmt.Errorf` when deriving the `error.type` attribute. (#8133) - `go.opentelemetry.io/otel/sdk/log` now unwraps error chains created with `fmt.Errorf` when deriving the `error.type` attribute from errors on log records. (#8133) - `Set.MarshalLog` method in `go.opentelemetry.io/otel/attribute` now uses `Value.String` formatting following the [OpenTelemetry AnyValue representation for non-OTLP protocols](https://opentelemetry.io/docs/specs/otel/common/#anyvalue). (#8169) - Optimize `go.opentelemetry.io/otel/sdk/metric` to return a drop reservoir and short-circuit `Offer` calls to the exemplar reservoir when `exemplar.AlwaysOffFilter` is configured. (#8211) (#8267) - Optimize `go.opentelemetry.io/otel/sdk/metric` to return a drop reservoir for asynchronous instruments when `exemplar.TraceBasedFilter` is configured. (#8286) ### Deprecated - Deprecate `Value.Emit` method in `go.opentelemetry.io/otel/attribute`. Use `Value.String` instead. (#8176) ### Fixed - Limit OTLP request size to 64 MiB by default in `go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc`. The limit applies before compression, oversized requests are treated as non-retryable errors, and the limit can be configured with the new `WithMaxRequestSize` option. (#8157, #8365) - Limit OTLP request size to 64 MiB by default in `go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp`. The limit applies before compression, oversized requests are treated as non-retryable errors, and the limit can be configured with the new `WithMaxRequestSize` option. (#8157, #8365) - Limit OTLP request size to 64 MiB by default in `go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetricgrpc`.

(#8157, #8365) - Limit OTLP request size to 64 MiB by default in `go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc`. The limit applies before compression, oversized requests are treated as non-retryable errors, and the limit can be configured with the new `WithMaxRequestSize` option. (#8157, #8365) - Limit OTLP request size to 64 MiB by default in `go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp`. The limit applies before compression, oversized requests are treated as non-retryable errors, and the limit can be configured with the new `WithMaxRequestSize` option. (#8157, #8365) - Fix gzipped request body replay on redirect in `go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp`. (#8135) - Fix gzipped request body replay on redirect in `go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp`. (#8152) - `go.opentelemetry.io/otel/exporters/prometheus` now uses `Value.String` formatting for label values following the [OpenTelemetry AnyValue representation for non-OTLP protocols](https://opentelemetry.io/docs/specs/otel/common/#anyvalue).

(#8226) - Fix a concurrent `Collect` data race and potential panic in `go.opentelemetry.io/otel/exporters/prometheus` when `WithResourceAsConstantLabels` option is used. (#8227) - Fix race condition in `FixedSizeReservoir` in `go.opentelemetry.io/otel/sdk/metric/exemplar` by reverting #7447. (#8249) - Fix `FixedSizeReservoir` in `go.opentelemetry.io/otel/sdk/metric/exemplar` to safely handle zero size. A capacity check in the constructor initializes the reservoir safely and skips initialization for zero-cap; early returns in `Offer()` and `Collect()` ensure no-op behavior. (#8295) - Fix counting of spans and logs in self-observability metrics in `go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc`, `go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp`, `go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc`, and `go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp`. (#8254) - Drop conflicting scope attributes named `name`, `version`, or `schema_url` from metric labels in `go.opentelemetry.io/otel/exporters/prometheus`, preserving the dedicated `otel_scope_name`, `otel_scope_version`, and `otel_scope_schema_url` labels. (#8264) - Close schema files opened by `ParseFile` in `go.opentelemetry.io/otel/schema/v1.0` and `go.opentelemetry.io/otel/schema/v1.1`. ([GHSA-995v-fvrw-c78m](GHSA-995v-fvrw-c78m)) - Enforce the 8192-byte baggage size limit during extraction/parsing, changing behavior when the limit is exceeded in `go.opentelemetry.io/otel/baggage` and `go.opentelemetry.io/otel/propagation`. (#8222) - Fix `go.opentelemetry.io/otel/semconv/v1.41.0` to include `Attr*` helper methods for required attributes on observable instruments. (#8361) - Limit baggage extraction error reporting in `go.opentelemetry.io/otel/propagation` to prevent malformed or oversized baggage headers from flooding logs.

([#8002](https://github.com/open-telemetry/opentelemetry-go/issues/8002)) ##### Changed - ⚠️ **Breaking Change:** `go.opentelemetry.io/otel/sdk/metric` now applies a default cardinality limit of 2000 to comply with the Metrics SDK specification recommendation. New attribute sets are dropped when the cardinality limit is reached. The measurement of these sets are aggregated into a special attribute set containing `attribute.Bool("otel.metric.overflow", true)`. This can break users who relied on the previous unlimited default. Set `WithCardinalityLimit(0)` or the deprecated `OTEL_GO_X_CARDINALITY_LIMIT=0` environment variable to preserve unlimited cardinality. Note that support for `OTEL_GO_X_CARDINALITY_LIMIT` may be removed in a future release.

fix(stdoutlog): update semconv import to v1.41.0 in test

a9320f5

The observ package uses semconv v1.41.0, but the test was importing v1.40.0, causing SchemaURL mismatch failures in TestObservability. Updates the test imports to match the actual package version.
