prometheus exporter ignores metrics from the Prometheus bridge (#7688)
Related to https://github.com/open-telemetry/opentelemetry-go/issues/7686. This makes the Prometheus exporter ignore all metrics from the Prometheus bridge. This is almost certainly a misconfiguration, but may happen when using autoexport or other packages that automatically install the bridge. |

Release v1.39.0 (#7676)
## Overview ### Added - Greatly reduce the cost of recording metrics in `go.opentelemetry.io/otel/sdk/metric` using hashing for map keys. (#7175) - Add `WithInstrumentationAttributeSet` option to `go.opentelemetry.io/otel/log`, `go.opentelemetry.io/otel/metric`, and `go.opentelemetry.io/otel/trace` packages. This provides a concurrent-safe and performant alternative to `WithInstrumentationAttributes` by accepting a pre-constructed `attribute.Set`. (#7287) - Add experimental observability for the Prometheus exporter in `go.opentelemetry.io/otel/exporters/prometheus`. Check the `go.opentelemetry.io/otel/exporters/prometheus/internal/x` package documentation for more information. (#7345) - Add experimental observability metrics in `go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc`. (#7353) - Add temporality selector functions `DeltaTemporalitySelector`, `CumulativeTemporalitySelector`, `LowMemoryTemporalitySelector` to `go.opentelemetry.io/otel/sdk/metric`. (#7434) - Add experimental observability metrics for simple log processor in `go.opentelemetry.io/otel/sdk/log`. (#7548) - Add experimental observability metrics in `go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc`. (#7459) - Add experimental observability metrics in `go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp`. (#7486) - Add experimental observability metrics for simple span processor in `go.opentelemetry.io/otel/sdk/trace`. (#7374) - Add experimental observability metrics in `go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp`. (#7512) - Add experimental observability metrics for manual reader in `go.opentelemetry.io/otel/sdk/metric`. (#7524) - Add experimental observability metrics for periodic reader in `go.opentelemetry.io/otel/sdk/metric`. (#7571) - Support `OTEL_EXPORTER_OTLP_LOGS_INSECURE` and `OTEL_EXPORTER_OTLP_INSECURE` environmental variables in `go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp`. (#7608) - Add `Enabled` method to the `Processor` interface in `go.opentelemetry.io/otel/sdk/log`. All `Processor` implementations now include an `Enabled` method. (#7639) - The `go.opentelemetry.io/otel/semconv/v1.38.0` package. The package contains semantic conventions from the `v1.38.0` version of the OpenTelemetry Semantic Conventions. See the [migration documentation](./semconv/v1.38.0/MIGRATION.md) for information on how to upgrade from `go.opentelemetry.io/otel/semconv/v1.37.0.`(#7648) ### Changed - `Distinct` in `go.opentelemetry.io/otel/attribute` is no longer guaranteed to uniquely identify an attribute set. Collisions between `Distinct` values for different Sets are possible with extremely high cardinality (billions of series per instrument), but are highly unlikely. (#7175) - `WithInstrumentationAttributes` in `go.opentelemetry.io/otel/trace` synchronously de-duplicates the passed attributes instead of delegating it to the returned `TracerOption`. (#7266) - `WithInstrumentationAttributes` in `go.opentelemetry.io/otel/meter` synchronously de-duplicates the passed attributes instead of delegating it to the returned `MeterOption`. (#7266) - `WithInstrumentationAttributes` in `go.opentelemetry.io/otel/log` synchronously de-duplicates the passed attributes instead of delegating it to the returned `LoggerOption`. (#7266) - Rename the `OTEL_GO_X_SELF_OBSERVABILITY` environment variable to `OTEL_GO_X_OBSERVABILITY` in `go.opentelemetry.io/otel/sdk/trace`, `go.opentelemetry.io/otel/sdk/log`, and `go.opentelemetry.io/otel/exporters/stdout/stdouttrace`. (#7302) - Improve performance of histogram `Record` in `go.opentelemetry.io/otel/sdk/metric` when min and max are disabled using `NoMinMax`. (#7306) - Improve error handling for dropped data during translation by using `prometheus.NewInvalidMetric` in `go.opentelemetry.io/otel/exporters/prometheus`. ⚠️ **Breaking Change:** Previously, these cases were only logged and scrapes succeeded. Now, when translation would drop data (e.g., invalid label/value), the exporter emits a `NewInvalidMetric`, and Prometheus scrapes **fail with HTTP 500** by default. To preserve the prior behavior (scrapes succeed while errors are logged), configure your Prometheus HTTP handler with: `promhttp.HandlerOpts{ ErrorHandling: promhttp.ContinueOnError }`. (#7363) - Replace fnv hash with xxhash in `go.opentelemetry.io/otel/attribute` for better performance. (#7371) - The default `TranslationStrategy` in `go.opentelemetry.io/exporters/prometheus` is changed from `otlptranslator.NoUTF8EscapingWithSuffixes` to `otlptranslator.UnderscoreEscapingWithSuffixes`. (#7421) - Improve performance of concurrent measurements in `go.opentelemetry.io/otel/sdk/metric`. (#7427) - Include W3C TraceFlags (bits 0–7) in the OTLP `Span.Flags` field in `go.opentelemetry.io/exporters/otlp/otlptrace/otlptracehttp` and `go.opentelemetry.io/exporters/otlp/otlptrace/otlptracegrpc`. (#7438) - The `ErrorType` function in `go.opentelemetry.io/otel/semconv/v1.37.0` now handles custom error types. If an error implements an `ErrorType() string` method, the return value of that method will be used as the error type. (#7442) ### Fixed - Fix `WithInstrumentationAttributes` options in `go.opentelemetry.io/otel/trace`, `go.opentelemetry.io/otel/metric`, and `go.opentelemetry.io/otel/log` to properly merge attributes when passed multiple times instead of replacing them. Attributes with duplicate keys will use the last value passed. (#7300) - The equality of `attribute.Set` when using the `Equal` method is not affected by the user overriding the empty set pointed to by `attribute.EmptySet` in `go.opentelemetry.io/otel/attribute`. (#7357) - Return partial OTLP export errors to the caller in `go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc`. (#7372) - Return partial OTLP export errors to the caller in `go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploghttp`. (#7372) - Return partial OTLP export errors to the caller in `go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetricgrpc`. (#7372) - Return partial OTLP export errors to the caller in `go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp`. (#7372) - Return partial OTLP export errors to the caller in `go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc`. (#7372) - Return partial OTLP export errors to the caller in `go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp`. (#7372) - Fix `AddAttributes`, `SetAttributes`, `SetBody` on `Record` in `go.opentelemetry.io/otel/sdk/log` to not mutate input. (#7403) - Do not double record measurements of `RecordSet` methods in `go.opentelemetry.io/otel/semconv/v1.37.0`. (#7655) - Do not double record measurements of `RecordSet` methods in `go.opentelemetry.io/otel/semconv/v1.36.0`. (#7656) ### Removed - Drop support for [Go 1.23]. (#7274) - Remove the `FilterProcessor` interface in `go.opentelemetry.io/otel/sdk/log`. The `Enabled` method has been added to the `Processor` interface instead. All `Processor` implementations must now implement the `Enabled` method. Custom processors that do not filter records can implement `Enabled` to return `true`. (#7639) |

sdk/log: move Enabled method from FilterProcessor to Processor (#7639)
Fixes #7617 Simplify the Logs SDK by unifying processor capabilities into a single interface. - Add `Enabled(ctx context.Context, p EnabledParameters) bool` to `sdk/log.Processor`. - Remove `sdk/log.FilterProcessor` interface. `Processor` implementations must now implement the `Enabled` method. Custom processors that do not filter records can implement `Enabled` to return `true`. |

feat: sdk/trace: span processed metric for simple span processor (#7374)
Fixes #7004 This PR adds support for experimental otel.sdk.processor.span.processed metric in simple span processor. Definition of metric at: https://github.com/open-telemetry/semantic-conventions/blob/v1.36.0/docs/otel/sdk-metrics.md Experimental metrics are behind a feature flag: `OTEL_GO_X_OBSERVABILITY` <details> <summary>Observability Implementation Checklist</summary> ## Observability Implementation Checklist Based on the [project Observability guidelines](https://github.com/open-telemetry/opentelemetry-go/blob/e4ab3141123d0811125a69823dbbe4d9ec5a9b8f/CONTRIBUTING.md#observability), ensure the following are completed: ### Environment Variable Activation * [x] Observability features are disabled by default * [x] Features are activated through the `OTEL_GO_X_OBSERVABILITY` environment variable * [x] Use consistent pattern with `x.Observability.Enabled()` check [^1] * [x] Follow established experimental feature pattern [^2][^3] [^1]: https://github.com/open-telemetry/opentelemetry-go/blob/e4ab3141123d0811125a69823dbbe4d9ec5a9b8f/exporters/stdout/stdouttrace/internal/observ/instrumentation.go#L101-L103 [^2]: https://github.com/open-telemetry/opentelemetry-go/blob/e4ab3141123d0811125a69823dbbe4d9ec5a9b8f/exporters/stdout/stdouttrace/internal/x/x.go [^3]: https://github.com/open-telemetry/opentelemetry-go/blob/e4ab3141123d0811125a69823dbbe4d9ec5a9b8f/sdk/internal/x/x.go ### Encapsulation * [x] Instrumentation is encapsulated within a dedicated `struct` (e.g., [`Instrumentation`](https://github.com/open-telemetry/opentelemetry-go/blob/e4ab3141123d0811125a69823dbbe4d9ec5a9b8f/exporters/stdout/stdouttrace/internal/observ/instrumentation.go#L86-L94)) * [x] Instrumentation is not mixed into the instrumented component * [x] Instrumentation code is in its own file or package if complex/reused * [x] Instrumentation setup doesn't bloat the main component code ### Initialization * [x] Initialization is only done when observability is enabled * [x] Setup is explicit and side-effect free * [x] Return errors from initialization when appropriate * [x] Use the global Meter provider (e.g., `otel.GetMeterProvider()`) * [x] Include proper meter configuration with: * [x] Instrumentation package name is used for the Meter * [x] Instrumentation version (e.g. [`Version`](https://github.com/open-telemetry/opentelemetry-go/blob/e4ab3141123d0811125a69823dbbe4d9ec5a9b8f/exporters/stdout/stdouttrace/internal/observ/instrumentation.go#L40-L43)) * [x] Schema URL (e.g. [`SchemaURL`](https://github.com/open-telemetry/opentelemetry-go/blob/e4ab3141123d0811125a69823dbbe4d9ec5a9b8f/exporters/stdout/stdouttrace/internal/observ/instrumentation.go#L36-L38)) ### Performance * [x] Little to no overhead when observability is disabled * [x] Expensive operations are only executed when observability is enabled * [x] When enabled, instrumentation code paths are optimized to reduce allocation/computation overhead #### Attribute and Option Allocation Management * [x] Use `sync.Pool` for attribute slices and options with dynamic attributes * [x] Pool objects are properly reset before returning to pool * [x] Pools are scoped for maximum efficiency while ensuring correctness #### Caching * [x] Static attribute sets known at compile time are pre-computed and cached * [x] Common attribute combinations use lookup tables/maps #### Benchmarking * [x] Benchmarks provided for all instrumentation code * [ ] Benchmark scenarios include both enabled and disabled observability * [x] Benchmark results show impact on allocs/op, B/op, and ns/op (use `b.ReportAllocs()` in benchmarks) ### Error Handling and Robustness * [x] Errors are reported back to caller when possible * [x] Partial failures are handled gracefully * [x] Use partially initialized components when available * [x] Return errors to caller instead of only using `otel.Handle()` * [x] Use `otel.Handle()` only when component cannot report error to user ### Context Propagation * [x] Observability measurements receive the context from the function being measured (don't break context propagation by using `context.Background()`) ### Semantic Conventions Compliance * [x] All metrics follow [OpenTelemetry Semantic Conventions](https://github.com/open-telemetry/semantic-conventions/blob/5ee549b1ce30fe11fcb9b7e3bd35ebfb363f467f/docs/otel/sdk-metrics.md) * [x] Use the [`otelconv`](https://pkg.go.dev/go.opentelemetry.io/otel@v1.38.0/semconv/v1.37.0/otelconv) convenience package for metric semantic conventions * [x] Component names follow semantic conventions * [x] Use package path scope type as stable identifier for non-standard components * [x] Component names are stable unique identifiers * [x] Use global counter for uniqueness if necessary * [x] Component ID counter is resettable for deterministic testing ### Testing * [x] Use deterministic testing with isolated state * [x] Restore previous state after tests (`t.Cleanup()`) * [x] Isolate meter provider for testing * [x] Use `t.Setenv()` for environment variable testing * [x] Reset component ID counter for deterministic component names * [x] Test order doesn't affect results </details> ### Benchmarks ```console > benchstat bmark.result goos: darwin goarch: arm64 pkg: go.opentelemetry.io/otel/sdk/trace/internal/observ cpu: Apple M1 Pro │ bmark.result │ │ sec/op │ SSP/SpanProcessed-8 146.7n ± 15%

This is when deduplication happens or data is truncated because of the limits. ``` goos: linux goarch: amd64 pkg: go.opentelemetry.io/otel/sdk/log cpu: 13th Gen Intel(R) Core(TM) i7-13800H │ old.txt │ new.txt │ │ sec/op │ sec/op vs base │ AddAttributes/Single/NoLimits-20 57.91n ± 19% 29.12n ± 5% -49.71% (p=0.000 n=10) AddAttributes/Single/AllowDuplicates-20 24.21n ± 2% 24.46n ± 17% +1.05% (p=0.011 n=10) AddAttributes/Unique/NoLimits-20 174.6n ± 8% 184.2n ± 7% +5.47% (p=0.027 n=10) AddAttributes/Unique/AllowDuplicates-20 69.79n ± 22% 67.83n ± 9% -2.81% (p=0.019 n=10) AddAttributes/Deduplication/Enabled-20 144.5n ± 4% 165.8n ± 4% +14.71% (p=0.000 n=10) AddAttributes/NestedDeduplication/Enabled-20 439.2n ± 2% 792.4n ± 11% +80.41% (p=0.000 n=10) AddAttributes/NestedDeduplication/Disabled-20 162.60n ± 1% 86.84n ± 5% -46.59% (p=0.000 n=10) AddAttributes/Deduplication/Disabled-20 68.15n ± 8% 67.59n ± 8% ~ (p=0.190 n=10) AddAttributes/CountLimit/Hit-20 629.1n ± 4% 621.0n ± 7% ~ (p=0.325 n=10) AddAttributes/CountLimit/NotHit-20 914.6n ± 7% 944.2n ± 13% ~ (p=0.393 n=10) AddAttributes/ValueLimit/Hit-20 133.5n ± 2% 162.1n ± 2% +21.43% (p=0.000 n=10) AddAttributes/ValueLimit/NotHit-20 115.8n ± 9% 131.2n ± 8% +13.26% (p=0.000 n=10) SetAttributes/Single/NoLimits-20 59.38n ± 2% 28.89n ± 22% -51.36% (p=0.000 n=10) SetAttributes/Single/AllowDuplicates-20 24.19n ± 1% 24.30n ± 2% ~ (p=0.867 n=10) SetAttributes/Unique/NoLimits-20 179.8n ± 2% 200.7n ± 6% +11.66% (p=0.000 n=10) SetAttributes/Unique/AllowDuplicates-20 72.65n ± 6% 71.91n ± 6% ~ (p=0.218 n=10) SetAttributes/Deduplication/Enabled-20 143.9n ± 6% 188.5n ± 12% +30.96% (p=0.000 n=10) SetAttributes/Deduplication/Disabled-20 77.68n ± 12% 69.20n ± 8% -10.92% (p=0.008 n=10) SetAttributes/NestedDeduplication/Enabled-20 443.7n ± 11% 770.8n ± 7% +73.75% (p=0.000 n=10) SetAttributes/NestedDeduplication/Disabled-20 172.60n ± 4% 91.73n ± 11% -46.85% (p=0.000 n=10) SetAttributes/CountLimit/Hit-20 629.1n ± 2% 631.3n ± 7% ~ (p=0.971 n=10) SetAttributes/CountLimit/NotHit-20 909.2n ± 8% 866.4n ± 7% ~ (p=0.143 n=10) SetAttributes/ValueLimit/Hit-20 135.5n ± 2% 150.2n ± 5% +10.85% (p=0.000 n=10) SetAttributes/ValueLimit/NotHit-20 121.7n ± 7% 137.2n ± 6% +12.65% (p=0.001 n=10) SetAttributes/Overwrite/Existing-20 176.0n ± 5% 184.1n ± 2% +4.60% (p=0.005 n=10) SetBody/Simple/NoLimits-20 13.54n ± 1% 13.34n ± 2% -1.48% (p=0.027 n=10) SetBody/Simple/WithLimits-20 13.46n ± 11% 13.91n ± 9% ~ (p=0.541 n=10) SetBody/UniqueMap/NoLimits-20 216.2n ± 8% 183.8n ± 3% -14.94% (p=0.000 n=10) SetBody/UniqueMap/AllowDuplicates-20 12.89n ± 1% 12.75n ± 1% -1.05% (p=0.001 n=10) SetBody/Deduplication/Enabled-20 113.5n ± 2% 164.4n ± 4% +44.85% (p=0.000 n=10) SetBody/Deduplication/Disabled-20 12.93n ± 41% 12.74n ± 1% -1.51% (p=0.000 n=10) SetBody/NestedDeduplication/Enabled-20 206.4n ± 2% 493.4n ± 2% +139.05% (p=0.000 n=10) SetBody/NestedDeduplication/Disabled-20 12.93n ± 1% 12.98n ± 11% ~ (p=0.515 n=10) SetBody/ValueLimit/Hit-20 86.22n ± 1% 110.25n ± 3% +27.87% (p=0.000 n=10) SetBody/ValueLimit/NoHit-20 85.52n ± 8% 104.25n ± 1% +21.91% (p=0.000 n=10) geomean 104.2n 107.1n +2.84% │ old.txt │ new.txt │ │ B/op │ B/op vs base │ AddAttributes/Single/NoLimits-20 0.000 ± 0% 0.000 ± 0% ~ (p=1.000 n=10) ¹ AddAttributes/Single/AllowDuplicates-20 0.000 ± 0% 0.000 ± 0% ~ (p=1.000 n=10) ¹ AddAttributes/Unique/NoLimits-20 0.000 ± 0% 0.000 ± 0% ~ (p=1.000 n=10) ¹ AddAttributes/Unique/AllowDuplicates-20 0.000 ± 0% 0.000 ± 0% ~ (p=1.000 n=10) ¹ AddAttributes/Deduplication/Enabled-20 0.0 ± 0% 128.0 ± 0% ?

OTLP trace exporter include W3C trace flags (bits 0–7) in Span.Flags (#7438)
Closes #7436 Span.Flags should include: Bits 0–7: span’s W3C TraceFlags (e.g., sampled) Bits 8–9: “has parent isRemote” and “parent isRemote” per OTLP spec Update the trace exporter to include the span’s W3C trace flags in the lower 8 bits and keep the existing 8–9 isRemote logic. Conceptually: For spans: flags := uint32(sd.SpanContext().TraceFlags() & 0xff) Always set SPAN_FLAGS_CONTEXT_HAS_IS_REMOTE_MASK If sd.Parent().IsRemote(), also set SPAN_FLAGS_CONTEXT_IS_REMOTE_MASK Assign s.Flags = flags Apply the same for links using the link’s SpanContext.TraceFlags() for bits 0–7 and the link’s SpanContext.IsRemote() for bits 8–9. --------- Co-authored-by: Damien Mathieu <42@dmathieu.com> |

Use sync.Map and atomics to improve sum performance (#7427)
Alternative to https://github.com/open-telemetry/opentelemetry-go/pull/7380 This uses a sync.Map and atomics for the sum's counter value. This intentionally introduces a new race condition that didn't previously exist: * It is possible for the exemplar to be recorded in the batch of metrics after the add() for cumulative sum aggregations. For cumulative, this isn't a huge issue since exemplars are expected to persist across collection cycles. This is difficult to fix because we can't manage the internal storage of an exemplar.Reservoir (to atomically swap between hot and cold storage). If we are able to make assumptions about how exemplar reservoirs are managed (i.e. that the number of and order of exemplars returned is always the same), then we could possibly fix this by merging at export time. ### Alternatives Considered #### RWLock for the map instead of sync.Map This is significantly less performant. #### Single sync.Map without hotColdWaitGroup Deleting keys from the sync.Map concurrently with measurements (during Clear() of the sync.Map) can cause measurements to be made to a counter that has already been read, exported and deleted. This can produce incorrect sums when delta is used. Instead, atomically switching writes to a completely empty sync.Map and waiting for writes to the previous sync.Map complete eliminates this issue. #### Use two sync.Map for cumulative sums One idea I explored was doing a hot-cold swap for cumulative sums just like we do for delta sums. We would swap the hot and cold sync.Maps, wait for writes to the cold sync.Map to complete while new writes go to the hot map. Then, once we are done reading the cold map, we could merge the contents of the cold map back into the new hot map. This approach has two issues: * It isn't possible to "merge" one exemplar reservoir into another. This is an issue for persistent exemplars that aren't overwritten in a collection interval. * We can't keep a consistent set of keys in overflow scenarios. Measurements that are made to the hot map before the merge of the cold into hot that should have been overflows will be added as new attribute sets. That, in turn, means we will need to change previously-exported attribute sets to the overflow set, which will cause issues for users. ### Benchmarks Parallel: ``` goos: linux goarch: amd64 pkg:

Support custom error type semantics (#7442)
Allow instrumentation to provide domain-specific error type values (i.e.
HTTP or gRPC status codes) for the "error.type" semantic attribute. This
is accomplished by passing an error value that implements the
`interface{ ErrorType string }` interface.

Add temporality selector functions (#7434)
From: https://github.com/open-telemetry/opentelemetry-go/pull/7346 This PR exposes the default TemporalitySelector funcs that are used by the OTel env var processing. The reason to expose these funcs is because there is some discrepancy in various vendor documentation on how to enable these settings using go option args WithTemporalitySelector https://cloud-native.slack.com/archives/C01NPAXACKT/p1757443233624599 --------- Co-authored-by: Damien Mathieu <42@dmathieu.com> Co-authored-by: David Ashpole <dashpole@google.com> |

Use Set hash in Distinct (2nd attempt) (#7175)
Re-opening https://github.com/open-telemetry/opentelemetry-go/pull/5028 with new benchmarks. For cases with 10 attributes, this reduces the overhead of metric measurements by ~80-90% (depending on lock contention). It introduces a small probability of collision for attribute sets in the metrics SDK. For an instrument with 1 million different attribute sets, the probability of a collision is approximately 2 * 10^-8. For a more "normal" cardinality of 1000 on an instrument, it is approximately 2 * 10^-17. ``` goos: linux goarch: amd64 pkg: go.opentelemetry.io/otel/attribute cpu: Intel(R) Xeon(R) CPU @ 2.20GHz │ main.txt │ hash.txt │ │ sec/op │ sec/op vs base │ EquivalentMapAccess/Empty-24 32.01n ± 2% 10.12n ± 4% -68.37% (p=0.002 n=6) EquivalentMapAccess/1_string_attribute-24 106.25n ± 2% 10.01n ± 5% -90.58% (p=0.002 n=6) EquivalentMapAccess/10_string_attributes-24 826.250n ± 1% 9.982n ± 11% -98.79% (p=0.002 n=6) EquivalentMapAccess/1_int_attribute-24 106.65n ± 2% 10.13n ± 3% -90.50% (p=0.002 n=6) EquivalentMapAccess/10_int_attributes-24 833.25n ± 2% 10.04n ± 5% -98.80% (p=0.002 n=6) geomean 190.3n 10.06n -94.72% ``` Parallel benchmarks: ``` goos: linux goarch: amd64 pkg: go.opentelemetry.io/otel/sdk/metric cpu: Intel(R) Xeon(R) CPU @ 2.20GHz │ main24.txt │ new24.txt │ │ sec/op │ sec/op vs base │ SyncMeasure/NoView/Int64Counter/Attributes/0-24 288.4n ± 13% 267.0n ± 16% ~ (p=0.180 n=6) SyncMeasure/NoView/Int64Counter/Attributes/1-24 372.7n ± 24% 303.3n ± 6% -18.61% (p=0.002 n=6) SyncMeasure/NoView/Int64Counter/Attributes/10-24 1862.5n ± 11% 302.2n ± 6% -83.77% (p=0.002 n=6) SyncMeasure/NoView/Float64Counter/Attributes/0-24 288.2n ± 5% 291.8n ± 14% ~ (p=0.589 n=6) SyncMeasure/NoView/Float64Counter/Attributes/1-24 374.8n ± 22% 326.2n ± 15% -12.98% (p=0.002 n=6) SyncMeasure/NoView/Float64Counter/Attributes/10-24 1984.0n ± 10% 277.9n ± 15% -85.99% (p=0.002 n=6) SyncMeasure/NoView/Int64UpDownCounter/Attributes/0-24 286.8n ± 13% 279.4n ± 14% ~ (p=0.818 n=6) SyncMeasure/NoView/Int64UpDownCounter/Attributes/1-24 415.4n ± 14% 309.5n ± 11% -25.47% (p=0.002 n=6) SyncMeasure/NoView/Int64UpDownCounter/Attributes/10-24 1923.0n ± 19% 294.1n ± 17% -84.71% (p=0.002 n=6) SyncMeasure/NoView/Float64UpDownCounter/Attributes/0-24 284.9n ± 5% 271.6n ± 11% ~ (p=0.240 n=6) SyncMeasure/NoView/Float64UpDownCounter/Attributes/1-24 382.9n ± 23% 295.7n ± 13% -22.78% (p=0.002 n=6) SyncMeasure/NoView/Float64UpDownCounter/Attributes/10-24 1787.0n ± 28% 289.2n ± 12% -83.81% (p=0.002 n=6) SyncMeasure/NoView/Int64Histogram/Attributes/0-24 283.4n ± 8% 269.9n ± 9% ~ (p=0.589 n=6) SyncMeasure/NoView/Int64Histogram/Attributes/1-24 300.7n ± 8% 270.1n ± 15% -10.16% (p=0.026 n=6) SyncMeasure/NoView/Int64Histogram/Attributes/10-24 1046.8n ± 24% 299.2n ± 16% -71.42% (p=0.002 n=6) SyncMeasure/NoView/Float64Histogram/Attributes/0-24 264.3n ± 12% 295.9n ± 5% +11.93% (p=0.026 n=6) SyncMeasure/NoView/Float64Histogram/Attributes/1-24 321.0n ± 8% 269.4n ± 11% -16.09% (p=0.002 n=6) SyncMeasure/NoView/Float64Histogram/Attributes/10-24 1052.2n ± 10% 274.6n ± 5% -73.90% (p=0.002 n=6) geomean 540.0n 287.7n -46.72% ``` Single-threaded benchmarks: ``` goos: linux goarch: amd64 pkg: go.opentelemetry.io/otel/sdk/metric cpu: Intel(R) Xeon(R) CPU @ 2.20GHz │ main1.txt │ new1.txt │ │ sec/op │ sec/op vs base │ SyncMeasure/NoView/Int64Counter/Attributes/0 130.95n ± 1% 97.99n ± 21% -25.17% (p=0.002 n=6) SyncMeasure/NoView/Int64Counter/Attributes/1 300.8n ± 7% 104.6n ± 3% -65.21% (p=0.002 n=6) SyncMeasure/NoView/Int64Counter/Attributes/10 1646.0n ± 2% 105.8n ± 2% -93.58% (p=0.002 n=6) SyncMeasure/NoView/Float64Counter/Attributes/0 132.65n ± 1% 99.28n ± 4% -25.16% (p=0.002 n=6) SyncMeasure/NoView/Float64Counter/Attributes/1 295.4n ± 3% 107.7n ± 3% -63.54% (p=0.002 n=6) SyncMeasure/NoView/Float64Counter/Attributes/10 1620.0n ± 1% 109.6n ± 4% -93.23% (p=0.002 n=6) SyncMeasure/NoView/Int64UpDownCounter/Attributes/0 132.85n ± 80% 99.34n ± 1% -25.22% (p=0.002 n=6) SyncMeasure/NoView/Int64UpDownCounter/Attributes/1 300.4n ± 1% 106.0n ± 1% -64.71% (p=0.002 n=6) SyncMeasure/NoView/Int64UpDownCounter/Attributes/10 1622.0n ± 1% 105.8n ± 1% -93.48% (p=0.002 n=6) SyncMeasure/NoView/Float64UpDownCounter/Attributes/0 134.90n ± 51% 99.16n ± 4% -26.49% (p=0.002 n=6) SyncMeasure/NoView/Float64UpDownCounter/Attributes/1 312.4n ± 34% 107.8n ± 2% -65.51% (p=0.002 n=6) SyncMeasure/NoView/Float64UpDownCounter/Attributes/10 1613.0n ± 23% 106.1n ± 1% -93.43% (p=0.002 n=6) SyncMeasure/NoView/Int64Histogram/Attributes/0 103.50n ± 17% 88.53n ± 1% -14.46% (p=0.002 n=6) SyncMeasure/NoView/Int64Histogram/Attributes/1 199.50n ± 16% 95.44n ± 2% -52.16% (p=0.002 n=6) SyncMeasure/NoView/Int64Histogram/Attributes/10 878.70n ± 2% 95.78n ± 2% -89.10% (p=0.002 n=6) SyncMeasure/NoView/Float64Histogram/Attributes/0 108.55n ± 54% 88.45n ± 1% -18.51% (p=0.002 n=6) SyncMeasure/NoView/Float64Histogram/Attributes/1 257.30n ± 14% 95.05n ± 2% -63.06% (p=0.002 n=6) SyncMeasure/NoView/Float64Histogram/Attributes/10 882.70n ± 18% 96.28n ± 1% -89.09% (p=0.002 n=6) geomean 355.2n 100.3n -71.77% ``` --------- Co-authored-by: Tyler Yahn <MrAlias@users.noreply.github.com> Co-authored-by: Robert Pająk <pellared@hotmail.com> |

trace,metric,log: change WithInstrumentationAttributes to not de-depuplicate the passed attributes in a closure (#7266)
WithInstrumentationAttributes is creating a closure with a reference to a slice which is later passed to attribute.NewSet. attribute.NewSet may mutate the slice, so this will lead to a data race when the option is applied concurrently. We can fix this by moving the call to attribute.NewSet outside the closure.

trace,metric,log: add WithInstrumentationAttributeSet option (#7287)
Per https://github.com/open-telemetry/opentelemetry-go/pull/7266#issuecomment-3237027300 Related to https://github.com/open-telemetry/opentelemetry-go/issues/7217 ## What This PR adds `WithInstrumentationAttributeSet` option functions to the `log`, `metric`, and `trace` packages as suggested in https://github.com/open-telemetry/opentelemetry-go/pull/7266#issuecomment-3237027300. These new functions provide a more concurrent-safe alternative to the existing `WithInstrumentationAttributes` functions by accepting a pre-constructed `attribute.Set` instead of variadic `attribute.KeyValue` parameters. ## Why As discussed in #7266, the existing `WithInstrumentationAttributes` functions can lead to data races when used concurrently because `attribute.NewSet()` may mutate the passed slice in-place. While the issue was partially addressed by moving the `attribute.NewSet()` call outside the closure, the best long-term solution is to provide an alternative that accepts an immutable `attribute.Set`. **Benefits:** 1. **Concurrent Safety**: Since `attribute.Set` is immutable, these functions are inherently safe for concurrent use 2. **Performance**: Avoids repeated calls to `attribute.NewSet()` when the same attributes are used multiple times 3. **Consistency**: Matches the existing pattern used in `metric.WithAttributeSet()` 4. **Flexibility**: Allows users to pre-compute attribute sets and reuse them Deprecating `WithInstrumentationAttributes` is out of scope. See https://github.com/open-telemetry/opentelemetry-go/pull/7287#issuecomment-3245820459. ## Benchmarks ``` goos: linux goarch: amd64 pkg: go.opentelemetry.io/otel/trace cpu: 13th Gen Intel(R) Core(TM) i7-13800H BenchmarkNewTracerConfig/with_no_options-20 280298306 4.268 ns/op 0 B/op 0 allocs/op BenchmarkNewTracerConfig/with_an_instrumentation_version-20 33389427 30.84 ns/op 0 B/op 0 allocs/op BenchmarkNewTracerConfig/with_a_schema_url-20 35441077 30.46 ns/op 0 B/op 0 allocs/op BenchmarkNewTracerConfig/with_instrumentation_attribute-20 17607649 88.23 ns/op 64 B/op 1 allocs/op BenchmarkNewTracerConfig/with_instrumentation_attribute_set-20 38336211 31.30 ns/op 0 B/op 0 allocs/op ``` ``` goos: linux goarch: amd64 pkg: go.opentelemetry.io/otel/metric cpu: 13th Gen Intel(R) Core(TM) i7-13800H BenchmarkNewMeterConfig/with_no_options-20 262998199 4.525 ns/op 0 B/op 0 allocs/op BenchmarkNewMeterConfig/with_an_instrumentation_version-20 40483780 29.31 ns/op 0 B/op 0 allocs/op BenchmarkNewMeterConfig/with_a_schema_url-20 39162420 30.58 ns/op 0 B/op 0 allocs/op BenchmarkNewMeterConfig/with_instrumentation_attribute-20 19900275 77.50 ns/op 64 B/op 1 allocs/op BenchmarkNewMeterConfig/with_instrumentation_attribute_set-20 37519020 31.93 ns/op 0 B/op 0 allocs/op ``` ``` goos: linux goarch: amd64 pkg: go.opentelemetry.io/otel/log cpu: 13th Gen Intel(R) Core(TM) i7-13800H BenchmarkNewLoggerConfig/with_no_options-20 271100760 4.322 ns/op 0 B/op 0 allocs/op BenchmarkNewLoggerConfig/with_an_instrumentation_version-20 38392390 30.77 ns/op 0 B/op 0 allocs/op BenchmarkNewLoggerConfig/with_a_schema_url-20 39615074 30.25 ns/op 0 B/op 0 allocs/op BenchmarkNewLoggerConfig/with_instrumentation_attribute-20 17108463 82.51 ns/op 64 B/op 1 allocs/op BenchmarkNewLoggerConfig/with_instrumentation_attribute_set-20 37746534 31.70 ns/op 0 B/op 0 allocs/op ``` |

trace,metric,log: WithInstrumentationAttributes options to merge attributes (#7300)
## What Fix `WithInstrumentationAttributes` options in `go.opentelemetry.io/otel/trace`, `go.opentelemetry.io/otel/metric`, and `go.opentelemetry.io/otel/log` to properly merge attributes when passed multiple times instead of replacing them. Attributes with duplicate keys will use the last value passed. ## Why Per https://github.com/open-telemetry/opentelemetry-go/pull/7287#pullrequestreview-3181379062 and https://github.com/open-telemetry/opentelemetry-go/pull/7287#issuecomment-3250085450 Not that this does not address https://github.com/open-telemetry/opentelemetry-go/issues/7217. This is left to a seperate PR to not scope creep this one. CC @axw --------- Co-authored-by: Damien Mathieu <42@dmathieu.com> |

trace: optimize id parsing and string functions (#6791)
With specialized routines, we can avoid the allocation of hex.DecodeString since we know the structure of the IDs. We can use `==` instead of bytes.Equal for arrays. From the Go [spec]: > Array types are comparable if their array element types are comparable. Two > array values are equal if their corresponding element values are equal. The > elements are compared in ascending index order, and comparison stops as soon > as two element values differ (or all elements have been compared).

sdk/trace: self-observability: batch span processor metrics (#6393)
Fixes https://github.com/open-telemetry/opentelemetry-go/issues/7005 Adds `otel.sdk.processor.span.queue.size`, `otel.sdk.processor.span.queue.capacity`, and `otel.sdk.processor.span.processed.count` metrics to the trace batch span processor. These are defined in https://github.com/open-telemetry/semantic-conventions/blob/cb11bb9bac24f4b0e95ad0f61ce01813d8ceada8/docs/otel/sdk-metrics.md, and are experimental. Because of this, metrics are behind the OTEL_GO_X_SELF_OBSERVABILITY feature gate. Given the feature is experimental, it always uses the global meterprovider when enabled. --------- Co-authored-by: Robert Pająk <pellared@hotmail.com> |

sdk/log: self-observability: log created metric (#7121)
Fixes https://github.com/open-telemetry/opentelemetry-go/issues/7015 Adds experimental `otel.sdk.log.created` metric to logger. Since this is experimental, metric is behind the OTEL_GO_X_SELF_OBSERVABILITY feature gate. Metric defined in https://github.com/open-telemetry/semantic-conventions/blob/v1.36.0/docs/otel/sdk-metrics.md. Given the feature is experimental, it always uses the global meterprovider when enabled. |
