go.opentelemetry.io/contrib/bridges/otelzap

Changed

• The go.opentelemetry.io/contrib/instrumentation/go.mongodb.org/mongo-driver/mongo/otelmongo instrumentation now accepts a WithCommandAttributeDisabled, so the caller can specify whether to opt-out of tracing the mongo command. (#712)
• Upgrade to v0.20.0 of go.opentelemetry.io/otel. (#758)
• The B3 and Jaeger propagators now store their debug or deferred state in the context.Context instead of the SpanContext. (#758)

Added

• Add NewResourceDetectorWithOptions and the WithAWSLogger option to go.opentelemetry.io/contrib/detectors/aws/ec2/v2, allowing a custom AWS SDK logging.Logger to be supplied to the EC2 resource detector. (#9132)
• Add go.opentelemetry.io/contrib/detectors/openshift, a new resource detector for OpenShift 4 clusters, ported from processor/resourcedetectionprocessor/internal/openshift in opentelemetry-collector-contrib. Detects k8s.cluster.name, and cloud.provider, cloud.platform and cloud.region for clusters running on AWS, Google Cloud and IBM Cloud; Azure clusters report cloud.provider and cloud.platform only. (#9499)
• Add go.opentelemetry.io/contrib/detectors/kubeadm, a new resource detector for kubeadm-provisioned Kubernetes clusters, ported from processor/resourcedetectionprocessor/internal/kubeadm in opentelemetry-collector-contrib. Detects k8s.cluster.name from the ClusterConfiguration document in the kube-system/kubeadm-config ConfigMap and k8s.cluster.uid from the kube-system namespace UID. (#9500)

Changed

• Client metrics in go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp no longer include attributes from the server-side Labeler, preventing attributes such as http.route from leaking into outbound requests. This is a breaking change for applications that use ContextWithLabeler to add custom client metric attributes: use ContextWithClientLabeler / ClientLabelerFromContext or the WithMetricAttributesFn option instead. Server-side use of ContextWithLabeler / LabelerFromContext is unchanged. (#8924)
• Stop emitting the legacy http.read_bytes and http.wrote_bytes attributes on the per-operation span events enabled by WithMessageEvents in go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp. The read and write events remain, while total body sizes continue to be recorded on the server span as http.request.body.size and http.response.body.size according to HTTP semantic conventions. (#9624)

Deprecated

• Deprecate go.opentelemetry.io/contrib/instrumentation/github.com/aws/aws-sdk-go-v2/otelaws. (#9707)
• Deprecate go.opentelemetry.io/contrib/propagators/aws. (#9706)
• Deprecate go.opentelemetry.io/contrib/samplers/probability/consistent. (#9633)
• Deprecate ReadBytesKey, ReadErrorKey, WroteBytesKey, and WriteErrorKey in go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp. The identifiers remain available and their values are unchanged, but WithMessageEvents no longer emits http.read_bytes or http.wrote_bytes. There is no semantic-convention replacement for per-read or per-write byte counts or the human-readable error fields. Use HTTPRequestBodySizeKey and HTTPResponseBodySizeKey from go.opentelemetry.io/otel/semconv/v1.43.0 to record total body sizes on the span. If an error causes the HTTP request to fail, set the span status to Error and record ErrorType(err) from go.opentelemetry.io/otel/semconv/v1.43.0 on the span. (#9624)

Fixed

• Treat empty Prometheus exporter environment variable values as unset in go.opentelemetry.io/contrib/exporters/autoexport, restoring the documented defaults. (#9636)
• Bound converter-owned recursive map, slice, array, and pointer traversal in go.opentelemetry.io/contrib/bridges/otellogr, go.opentelemetry.io/contrib/bridges/otellogrus, go.opentelemetry.io/contrib/bridges/otelslog, and go.opentelemetry.io/contrib/bridges/otelzap. A field requiring more than 100 such levels is replaced with <max-depth-exceeded> and the record continues to be emitted. Existing fmt and user-method behavior remains unchanged. (#9691)
• Format span attributes in go.opentelemetry.io/contrib/zpages using attribute.Value.String instead of the deprecated attribute.Value.Emit, following the OpenTelemetry AnyValue representation for non-OTLP protocols. (#9453)
• Set error.type on the span and on the request-duration, request-body-size, and response-body-size metrics when a client disconnects mid-request in go.opentelemetry.io/contrib/instrumentation/github.com/gin-gonic/gin/otelgin, using the request context's cancellation error as the classification source when the handler has not already recorded an error via c.Error. Previously a disconnect was recorded with span status Error and no error.type, indistinguishable from a genuine server fault. (#9394)
• Report Prometheus metrics HTTP server errors in go.opentelemetry.io/contrib/otelconf when using the v0.2.0 configuration schema. The error check was inverted, so a clean shutdown (http.ErrServerClosed) was reported as unexpected while real Serve errors were ignored. (#9653)
• Fix temporary file cleanup for multipart requests in go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp by copying the parsed multipart form back to the original request during deferred cleanup, preserving net/http cleanup during panic unwinding for HTTP/2 panic handling and outer recovery middleware paths. Unrecovered HTTP/1 handler panics remain uncleaned because net/http skips finishRequest in that path. (#9685)
• Fix http.client.request.body.size recording for streaming request bodies in go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp. (#8684)
• Bound Kubernetes ConfigMap requests in go.opentelemetry.io/contrib/detectors/aws/eks with a 10-second timeout so Detect cannot hang indefinitely when the caller-provided context has no deadline. (#9419)

Removed

• Drop support for [Go 1.25]. (#9584)
• Remove go.opentelemetry.io/contrib/instrumentation/github.com/labstack/echo/otelecho. Use github.com/labstack/echo-opentelemetry instead. (#9613)

This release is the last to support [Go 1.25]. The next release will require at least [Go 1.26].

Added

• Add support for the aws.ec2 resource detector in go.opentelemetry.io/contrib/otelconf/x. (#9139)
• Support testing of [Go 1.27]. (#9524)
• Add go.opentelemetry.io/contrib/detectors/docker, a resource detector for Docker, ported from processor/resourcedetectionprocessor/internal/docker in opentelemetry-collector-contrib. (#9001)
• Add S3AttributeBuilder to go.opentelemetry.io/contrib/instrumentation/github.com/aws/aws-sdk-go-v2/otelaws that sets S3-specific span attributes following the OpenTelemetry S3 semantic conventions. (#9292)

Deprecated

• Deprecate go.opentelemetry.io/contrib/instrumentation/github.com/labstack/echo/otelecho. Use github.com/labstack/echo-opentelemetry instead. (#9136)

Fixed

• Record error.type attribute on server spans in go.opentelemetry.io/contrib/instrumentation/github.com/emicklei/go-restful/otelrestful when a request is cancelled or ends in a 5xx error. (#9387)
• Report ot-baggage-* extraction errors from go.opentelemetry.io/contrib/propagators/ot to otel.Handle instead of silently discarding them, while still attaching the successfully parsed baggage members to the context. (#9395)
• Set error.type on the rpc.client.call.duration and rpc.server.call.duration metrics in go.opentelemetry.io/contrib/instrumentation/google.golang.org/grpc/otelgrpc when the RPC fails with a non-OK status, per the RPC semantic conventions. (#9429)
• Reject OTLP exporter headers with an empty name in go.opentelemetry.io/contrib/otelconf, go.opentelemetry.io/contrib/otelconf/x, and go.opentelemetry.io/contrib/otelconf/v0.3.0, instead of forwarding invalid header names to OTLP exporters. (#9102)
• go.opentelemetry.io/contrib/detectors/aws/lambda no longer returns an error when run outside of an AWS Lambda environment, matching the no-op behavior of other resource detectors. (#9464)
• Convert Prometheus untyped metrics to OTLP Gauges in go.opentelemetry.io/contrib/bridges/prometheus. (#9099)

Added

• Add go.opentelemetry.io/contrib/detectors/ibmcloud/vpc, a new resource detector for IBM Cloud VPC virtual server instances, ported from github.com/open-telemetry/opentelemetry-collector-contrib/processor/resourcedetectionprocessor/internal/ibmcloud/vpc. Detects cloud.provider, cloud.platform, cloud.region, cloud.availability_zone, cloud.account.id, cloud.resource_id, host.id, host.image.id, host.image.name, host.name, and host.type. (#9011)
• Add go.opentelemetry.io/contrib/detectors/k8sapi, a new resource detector that queries the Kubernetes API. Detects k8s.node.name and k8s.node.uid when K8S_NODE_NAME is set via the downward API, and k8s.cluster.uid derived from the kube-system namespace UID (works on any Kubernetes distribution). (#9108)
• Add new elasticbeanstalk resource detector for AWS Elastic Beanstalk, ported from processor/resourcedetectionprocessor/internal/aws/elasticbeanstalk in opentelemetry-collector-contrib. (#8993)
• The resource created by go.opentelemetry.io/contrib/otelconf now includes default SDK attributes. (#8990)
• Add support for the aws.ecs resource detector in go.opentelemetry.io/contrib/otelconf/x. (#8915)
• Add support for the aws.eks resource detector in go.opentelemetry.io/contrib/otelconf/x. (#9138)
• Add support for the azure.vm resource detector in go.opentelemetry.io/contrib/otelconf/x. (#9074)
• Add support for the gcp resource detector in go.opentelemetry.io/contrib/otelconf/x. (#9137)
• Add go.opentelemetry.io/contrib/detectors/azure/azureappservice, a new resource detector for Azure App Service. Detects cloud.*, service.name, azure.resource_group.name, azure.app_service.instance.id, and deployment.environment.name from the WEBSITE_* and REGION_NAME environment variables. (#9289)
• Add azurecontainerapps resource detector for Azure Container Apps. (#8939)
• Add go.opentelemetry.io/contrib/detectors/azure/azurefunctions, a new resource detector for Azure Functions. Detects cloud.*, service.name, azure.resource_group.name, faas.instance, and deployment.environment.name from the FUNCTIONS_*, WEBSITE_*, CONTAINER_NAME, and REGION_NAME environment variables. (#9290)
• Add NewResourceDetector along with the WithAttributeFilter and WithTagKeyFilter options in go.opentelemetry.io/contrib/detectors/azure/azurevm. WithAttributeFilter restricts the returned resource to the attributes the filter accepts. WithTagKeyFilter opts in to azure.tag.<name> attributes for the VM tags whose keys satisfy the provided predicate; no VM tags are emitted without it. (#9162)
• Add go.opentelemetry.io/contrib/detectors/vultr — a new resource detector for Vultr Cloud Compute instances, ported from processor/resourcedetectionprocessor/internal/vultr in opentelemetry-collector-contrib. Detects cloud.provider, cloud.platform, cloud.region, host.id, and host.name. (#8995)

Changed

• Upgrade go.opentelemetry.io/otel/semconv to v1.43.0, including updates across instrumentation and detector modules. See semantic-conventions v1.43.0 release for complete details. (#9337)
• Upgrade go.opentelemetry.io/otel/semconv to v1.42.0, including updates across instrumentation and detector modules. See semantic-conventions v1.42.0 release for complete details. (#9196)
• Use direct normalized-key lookups in Carrier.Get and Carrier.Keys in go.opentelemetry.io/contrib/propagators/envcar. (#9112)
• Update log bridge conversions to use attribute key-values instead of the removed log key-values in go.opentelemetry.io/contrib/bridges/otellogr, go.opentelemetry.io/contrib/bridges/otellogrus, go.opentelemetry.io/contrib/bridges/otelslog, and go.opentelemetry.io/contrib/bridges/otelzap. (#9180)
• The Version() function in go.opentelemetry.io/contrib/instrumentation/github.com/gorilla/mux/otelmux has been replaced by const Version. (#9076)
• Set error.type attribute instead of adding exception span events in go.opentelemetry.io/contrib/instrumentation/github.com/gin-gonic/gin/otelgin. (#8977)
• Prefer the gRPC dial target over the resolved peer IP for the server.address and server.port attributes in go.opentelemetry.io/contrib/instrumentation/google.golang.org/grpc/otelgrpc. (#8904)
• The detector in go.opentelemetry.io/contrib/detectors/azure/azurevm now also detects cloud.account.id, cloud.availability_zone, azure.vm.name, azure.vm.size, azure.vm.scaleset.name, and azure.resource_group.name, and prefers osProfile.computerName for host.name (falling back to the VM name), reconciling it with the collector-contrib Azure resource detector. (#9162)

Fixed

• Fix Prometheus reader resource label filter configuration in go.opentelemetry.io/contrib/otelconf/v0.2.0. (#9062)
• Apply resource.detection/development.attributes.included and excluded filtering to resource detector attributes in go.opentelemetry.io/contrib/otelconf/x. (#9131)
• Honor the context configured with WithContext when constructing resources in go.opentelemetry.io/contrib/otelconf and go.opentelemetry.io/contrib/otelconf/x. (#9160)
• Handle nil response bodies from custom RoundTripper implementations in go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp without panicking. (#9184)
• Fix incorrect (overestimated) sum calculation for runtime histograms in go.opentelemetry.io/contrib/instrumentation/runtime. (#9063)
• Fix Severity.UnmarshalText round trip for positive FATAL offsets above the named range in go.opentelemetry.io/contrib/processors/minsev. (#9197)
• Reduce binary size by fetching ConfigMaps via rest.HTTPClientFor instead of the Kubernetes clientset in go.opentelemetry.io/contrib/detectors/aws/eks. (#9284)
• TextMapPropagator in go.opentelemetry.io/contrib/propagators/autoprop returns the no-op propagator for empty input, matching the behavior of none. An unknown OTEL_PROPAGATORS value still returns an error with a nil propagator so NewTextMapPropagator falls back to the default TraceContext and Baggage propagators instead of disabling propagation. (#9163)
• Preserve error-valued attributes nested in a group as grouped attributes instead of silently dropping them in go.opentelemetry.io/contrib/bridges/otelslog. (#9238)
• Fix a data race in go.opentelemetry.io/contrib/bridges/otelslog where concurrent Handle calls could corrupt each other's log attributes because kvBuffer.KeyValues returned a slice aliasing a shared buffer. (#9229)
• Avoid a panic in go.opentelemetry.io/contrib/bridges/otelzap when a malformed error field contains a nil or non-error value. (#9068)
• Use azure.container_app.instance.id instead of service.instance.id for the replica name detected by go.opentelemetry.io/contrib/detectors/azure/azurecontainerapps. (#9208)
• Preserve the underlying metadata errors returned with partial resources from go.opentelemetry.io/contrib/detectors/gcp. (#9069)
• Copy MultipartForm back to the request otelmux.Middleware was given after the wrapped handler returns, so net/http can find and remove the temp files ParseMultipartForm created on the context-derived request copy, when otelmux.Middleware wraps a handler directly, in go.opentelemetry.io/contrib/instrumentation/github.com/gorilla/mux/otelmux. This does not cover a handler panic, nor the common router.Use(...) integration, where gorilla/mux's own routing step makes an additional request copy the middleware cannot write back through; see gorilla/mux#777. (#9361)
• Report the b3 header from Fields() for the default B3Unspecified single-header injection encoding, matching what Inject writes, in go.opentelemetry.io/contrib/propagators/b3. (#9273)
• Fix go.opentelemetry.io/contrib/propagators/aws/xray producing deterministic trace and span IDs when the seed read from crypto/rand silently failed, by switching to math/rand/v2's concurrency-safe top-level generator. (#9359)
• Strip connection number suffix from connection ID in go.opentelemetry.io/contrib/instrumentation/go.mongodb.org/mongo-driver/v2/mongo/otelmongo to prevent unbounded metric cardinality. (#9352)
• Strip connection number suffix from connection ID in go.opentelemetry.io/contrib/instrumentation/go.mongodb.org/mongo-driver/mongo/otelmongo so the network.peer.address and net.peer.name span attributes reflect the actual host instead of the raw connection ID. (#9352)
• Record network.protocol.version (and network.protocol.name) from the response's negotiated protocol instead of the request's stamped Proto in go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp, so an HTTP/1.1-shaped request that gets upgraded to HTTP/2 via ALPN is no longer misreported as HTTP/1.1 on the client span and request metrics. (#9371)

Added

• Add error.type attribute to http.client.request.duration for transport failures in otelhttp. (#8801)
• Add examples for prometheus compatibility document. (#8716)
• Add support for cardinality_limits in PeriodicMetricReader in otelconf. (#8885)
• Add Resource method to SDK in go.opentelemetry.io/contrib/otelconf/x to expose the resolved SDK resource from declarative configuration. (#8913)
• Add go.opentelemetry.io/contrib/detectors/hetzner, a new resource detector for Hetzner Cloud servers, ported from github.com/open-telemetry/opentelemetry-collector-contrib/processor/resourcedetectionprocessor/internal/hetzner. Detects cloud.provider, cloud.platform, cloud.region, cloud.availability_zone, host.id, and host.name. (#8979)

Changed

• Set error field as record.SetErr instead of a plain attribute in go.opentelemetry.io/contrib/bridges/otellogrus. (#8776)
• Set the "error" field (e.g. created via zap.Error) as record.SetErr instead of a plain attribute in go.opentelemetry.io/contrib/bridges/otelzap. (#8719)
• Set fields implementing error interface from slog records as record.SetErr instead of plain attributes in go.opentelemetry.io/contrib/bridges/otelslog. (#8774)
• Set emitted errors in go.opentelemetry.io/contrib/bridges/otellogr as record errors (Record.SetErr) instead of exception.message attributes. (#8775)

Fixed

• Fix header attributes lost when using sub-spans in go.opentelemetry.io/contrib/instrumentation/net/http/httptrace/otelhttptrace. (#8797)
• Validate encoding configuration for OTLP HTTP exporters in go.opentelemetry.io/contrib/otelconf. (#8772)
• Remove the custom body wrapper from the request's body after the request is processed to allow body type comparisons with the original type in go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp and go.opentelemetry.io/contrib/instrumentation/github.com/gorilla/mux/otelmux. (#6914)
• Unknown or empty HTTP methods now report "_OTHER" instead of "GET" across all HTTP instrumentations to align with OpenTelemetry semantic conventions. (#8868)
• The default span name formatter in go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp now conforms to the OpenTelemetry HTTP semantic conventions for server span names. (#8871)
  • The default span name is now {method} {route} (e.g. GET /foo/{id}) when a route pattern is available, or {method} (e.g. GET) otherwise.

Removed

• Remove the deprecated WithSpanOptions option in go.opentelemetry.io/contrib/instrumentation/google.golang.org/grpc/otelgrpc. (#8991)

Added

• Add Resource method to SDK in go.opentelemetry.io/contrib/otelconf/v0.3.0 to expose the resolved SDK resource from declarative configuration. (#8660)
• Add support to set the configuration file via OTEL_CONFIG_FILE in go.opentelemetry.io/contrib/otelconf. (#8639)
• Add support for service resource detector in go.opentelemetry.io/contrib/otelconf. (#8674)
• Add support for attribute_count_limit and attribute_value_length_limit in tracer provider configuration in go.opentelemetry.io/contrib/otelconf. (#8687)
• Add support for attribute_count_limit and attribute_value_length_limit in logger provider configuration in go.opentelemetry.io/contrib/otelconf. (#8686)
• Add support for server.address and server.port attributes in go.opentelemetry.io/contrib/instrumentation/google.golang.org/grpc/otelgrpc. (#8723)
• Add support for OTEL_SEMCONV_STABILITY_OPT_IN in go.opentelemetry.io/contrib/instrumentation/google.golang.org/grpc/otelgrpc. Supported values are rpc (default), rpc/dup and rpc/old. (#8726)
• Add the http.route metric attribute to go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp. (#8632)

Changed

• Prepend _ to the normalized environment variable name when the key starts with a digit in go.opentelemetry.io/contrib/propagators/envcar, ensuring POSIX compliance. (#8678)
• Move experimental types from go.opentelemetry.io/contrib/otelconf to go.opentelemetry.io/contrib/otelconf/x. (#8529)
• Normalize cached environment variable names in go.opentelemetry.io/contrib/propagators/envcar, aligning Carrier.Keys output with the carrier's normalized key format. (#8761)

Fixed

• Fix go.opentelemetry.io/contrib/otelconf Prometheus reader converting OTel dot-style label names (e.g. service.name) to underscore-style (service_name) in target_info when both without_type_suffix and without_units are set. Use NoTranslation instead of UnderscoreEscapingWithoutSuffixes to preserve dot-style label names while still suppressing metric name suffixes. (#8763)
• Limit the request body size at 1MB in go.opentelemetry.io/contrib/zpages. (#8656)
• Fix server spans using the client's address and port for server.address and server.port attributes in go.opentelemetry.io/contrib/instrumentation/google.golang.org/grpc/otelgrpc. (#8723)

Removed

• Host ID resource detector has been removed when configuring the host resource detector in go.opentelemetry.io/contrib/otelconf. (#8581)

Deprecated

• Deprecate OTEL_EXPERIMENTAL_CONFIG_FILE in favour of OTEL_CONFIG_FILE in go.opentelemetry.io/contrib/otelconf. (#8639)

Added

• Add environment variables propagation carrier in go.opentelemetry.io/contrib/propagators/envcar. (#8442)

Changed

• Upgrade go.opentelemetry.io/otel/semconv to v1.40.0, including updates across instrumentation and detector modules. (#8631)

  • The semantic conventions v1.40.0 release introduces RPC breaking changes applied in this repository:
    • RPC spans and metrics no longer include network.protocol.name, network.protocol.version, or network.transport attributes.
    • rpc.client.request.size, rpc.client.response.size, rpc.server.request.size, and rpc.server.response.size are no longer emitted in go.opentelemetry.io/contrib/instrumentation/google.golang.org/grpc/otelgrpc.
    • rpc.message span events and their message attributes are no longer emitted in go.opentelemetry.io/contrib/instrumentation/google.golang.org/grpc/otelgrpc (including when WithMessageEvents is configured).

  See semantic-conventions v1.40.0 release for complete details.

Fixed

• Ignore informational response status codes (100-199) except 101 Switching Protocols when storing the HTTP status code in go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp and go.opentelemetry.io/contrib/instrumentation/github.com/gorilla/mux/otelmux. (#6913)
• Make Body handling in Transport consistent with stdlib in go.opentelemetry.io/contrib/instrumentation/net/http/otelhttp. (#8618)

• Host resource detector in go.opentelemetry.io/contrib/otelconf now includes os. attributes. (#8578)

Removed

• Drop support for [Go 1.24]. (#8628)

This release is the last to support [Go 1.24]. The next release will require at least [Go 1.25].

Added

• Add WithSpanKind option in go.opentelemetry.io/contrib/instrumentation/google.golang.org/grpc/otelgrpc to override the default span kind. (#8506)
• Add const Version in go.opentelemetry.io/contrib/bridges/otelzap. (#8544)

• Change the rpc.response.status_code attribute to the canonical UPPER_SNAKE_CASE format in go.opentelemetry.io/contrib/instrumentation/google.golang.org/grpc/otelgrpc. (#8565)
• Enforce that client_certificate_file and client_key_file are provided together in go.opentelemetry.io/contrib/otelconf. (#8450)
• Fix broken CSS and JavaScript CDN URLs in go.opentelemetry.io/contrib/zpages by replacing the inaccessible code.getmdl.io CDN with cdnjs.cloudflare.com. (#8502)
• Use Prometheus translation strategy instead of deprecated funcs in go.opentelemetry.io/contrib/otelconf. (#8595)

Removed

• Remove the deprecated zipkin exporter example in go.opentelemetry.io/contrib/examples/zipkin. (#8501)
