Overview
Added
  • Add Reset method to SpanRecorder in go.opentelemetry.io/otel/sdk/trace/tracetest. (#​5994)
  • Add EnabledInstrument interface in go.opentelemetry.io/otel/sdk/metric/internal/x. This is an experimental interface that is implemented by synchronous instruments provided by go.opentelemetry.io/otel/sdk/metric. Users can use it to avoid performing computationally expensive operations when recording measurements. It does not fall within the scope of the OpenTelemetry Go versioning and stability policy and it may be changed in backwards incompatible ways or removed in feature releases. (#​6016)
Changed
  • The default global API now supports full auto-instrumentation from the go.opentelemetry.io/auto package. See that package for more information. (#​5920)

  • Add InstrumentationScope field to SpanStub in go.opentelemetry.io/otel/sdk/trace/tracetest, as a replacement for the deprecated InstrumentationLibrary. (#​5627)
  • Make the initial release of go.opentelemetry.io/otel/exporters/otlp/otlplog/otlploggrpc. This new module contains an OTLP exporter that transmits log telemetry using gRPC. This module is unstable and breaking changes may be introduced. See our versioning policy for more information about these stability guarantees. (#​5629)

  • Add WithProxy option in go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlptracehttp. (#​4906)
  • Add AddLink method to the Span interface in go.opentelemetry.io/otel/trace. (#​5032)
  • The Enabled method is added to the Logger interface in go.opentelemetry.io/otel/log. This method is used to notify users if a log record will be emitted or not. (#​5071)
  • Add SeverityUndefined const to go.opentelemetry.io/otel/log. This value represents an unset severity level. (#​5072)
  • Add Empty function in go.opentelemetry.io/otel/log to return a KeyValue for an empty value. (#​5076)
  • Add go.opentelemetry.io/otel/log/global to manage the global LoggerProvider. This package is provided with the anticipation that all functionality will be migrate to go.opentelemetry.io/otel when go.opentelemetry.io/otel/log stabilizes. At which point, users will be required to migrage their code, and this package will be deprecated then removed. (#​5085)
  • Add support for Summary metrics in the go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetrichttp and go.opentelemetry.io/otel/exporters/otlp/otlpmetric/otlpmetricgrpc exporters. (#​5100)

This release brings a breaking change for custom trace API implementations. Some interfaces (TracerProvider, Tracer, Span) now embed the go.opentelemetry.io/otel/trace/embedded types. Implementors need to update their implementations based on what they want the default behavior to be.

  • The exporter from go.opentelemetry.io/otel/exporters/zipkin is updated to use the v1.16.0 version of semantic conventions. This means it no longer uses the removed net.peer.ip or http.host attributes to determine the remote endpoint. Instead it uses the net.sock.peer attributes. (#​3581)

Added
  • The WithView Option is added to the go.opentelemetry.io/otel/sdk/metric package. This option is used to configure the view(s) a MeterProvider will use for all Readers that are registered with it. (#​3387)

  • The View type and related NewView function to create a view according to the OpenTelemetry specification are added to go.opentelemetry.io/otel/sdk/metric. These additions are replacements for the View type and New function from go.opentelemetry.io/otel/sdk/metric/view. (#​3459)
  • The Instrument and InstrumentKind type are added to go.opentelemetry.io/otel/sdk/metric. These additions are replacements for the Instrument and InstrumentKind types from go.opentelemetry.io/otel/sdk/metric/view. (#​3459)

  • The AssertHasAttributes allows instrument authors to test that datapoints returned have appropriate attributes. (#​3487)
Changed
  • The "go.opentelemetry.io/otel/sdk/metric".WithReader option no longer accepts views to associate with the Reader. Instead, views are now registered directly with the MeterProvider via the new WithView option. The views registered with the MeterProvider apply to all Readers. (#​3387)

  • The periodic reader in the go.opentelemetry.io/otel/sdk/metric package now uses the temporality and aggregation selectors from its configured exporter instead of accepting them as options. (#​3260)
Fixed
  • The go.opentelemetry.io/otel/exporters/prometheus exporter fixes duplicated _total suffixes. (#​3369)
  • Remove comparable requirement for Readers. (#​3387)
  • Cumulative metrics from the OpenCensus bridge (go.opentelemetry.io/otel/bridge/opencensus) are defined as monotonic sums, instead of non-monotonic. (#​3389)

  • Exported Status codes in the go.opentelemetry.io/otel/exporters/zipkin exporter are now exported as all upper case values. (#​3340)

v1.11.1: /v0.33.0

Compare Source

Added
  • The Prometheus exporter in go.opentelemetry.io/otel/exporters/prometheus registers with a Prometheus registerer on creation. By default, it will register with the default Prometheus default registerer. A non-default registerer can be used by passing the WithRegisterer option. (#​3239)
  • Added the WithAggregationSelector option to the go.opentelemetry.io/otel/exporters/prometheus package to change the default AggregationSelector used. (#​3341)
  • The Prometheus exporter in go.opentelemetry.io/otel/exporters/prometheus converts the Resource associated with metric exports into a target_info metric. (#​3285)
Changed
  • The "go.opentelemetry.io/otel/exporters/prometheus".New function is updated to return an error. It will return an error if the exporter fails to register with Prometheus. (#​3239)
Fixed
  • The URL-encoded values from the OTEL_RESOURCE_ATTRIBUTES environment variable are decoded. (#​2963)
  • The baggage.NewMember function decodes the value parameter instead of directly using it. This fixes the implementation to be compliant with the W3C specification. (#​3226)
  • Slice attributes of the attribute package are now comparable based on their value, not instance. (#​3108 #​3252)
  • The Shutdown and ForceFlush methods of the "go.opentelemetry.io/otel/sdk/trace".TraceProvider no longer return an error when no processor is registered. (#​3268)
  • The Prometheus exporter in go.opentelemetry.io/otel/exporters/prometheus cumulatively sums histogram buckets. (#​3281)
  • The sum of each histogram data point is now uniquely exported by the go.opentelemetry.io/otel/exporters/otlpmetric exporters. (#​3284, #​3293)
  • Recorded values for asynchronous counters (Counter and UpDownCounter) are interpreted as exact, not incremental, sum values by the metric SDK. (#​3350, #​3278)
  • UpDownCounters are now correctly output as Prometheus gauges in the go.opentelemetry.io/otel/exporters/prometheus exporter. (#​3358)
  • The Prometheus exporter in go.opentelemetry.io/otel/exporters/prometheus no longer describes the metrics it will send to Prometheus on startup. Instead the exporter is defined as an "unchecked" collector for Prometheus. This fixes the reader is not registered warning currently emitted on startup. (#​3291 #​3342)
  • The go.opentelemetry.io/otel/exporters/prometheus exporter now correctly adds _total suffixes to counter metrics. (#​3360)
  • The go.opentelemetry.io/otel/exporters/prometheus exporter now adds a unit suffix to metric names. This can be disabled using the WithoutUnits() option added to that package. (#​3352)

v1.11.0: /v0.32.3

Retracts the v0.32.2 version of go.opentelemetry.io/otel/exporters/otlpmetric/otlpmetricgrpc and go.opentelemetry.io/otel/exporters/otlpmetric/otlpmetrichttp given they include unresolvable dependencies.

Added
  • Add default User-Agent header to OTLP exporter requests (go.opentelemetry.io/otel/exporters/otlptrace/otlptracegrpc and go.opentelemetry.io/otel/exporters/otlptrace/otlptracehttp). (#​3261)
Changed
  • span.SetStatus has been updated such that calls that lower the status are now no-ops. (#​3214)
  • Upgrade golang.org/x/sys/unix from v0.0.0-20210423185535-09eb48e85fd7 to v0.0.0-20220919091848-fb04ddd9f9c8. This addresses GO-2022-0493. (#​3235)
