Changed

  • Jaeger and Zipkin exporter use github.com/go-logr/logr as the logging interface, and add the WithLogr option. (#3497, #3500)
  • Instrument configuration in go.opentelemetry.io/otel/metric/instrument is split into specific options and confguration based on the instrument type. (#3507)
    • Use the added Int64Option type to configure instruments from go.opentelemetry.io/otel/metric/instrument/syncint64.
    • Use the added Float64Option type to configure instruments from go.opentelemetry.io/otel/metric/instrument/syncfloat64.
    • Use the added Int64ObserverOption type to configure instruments from go.opentelemetry.io/otel/metric/instrument/asyncint64.
    • Use the added Float64ObserverOption type to configure instruments from go.opentelemetry.io/otel/metric/instrument/asyncfloat64.
  • Return a Registration from the RegisterCallback method of a Meter in the go.opentelemetry.io/otel/metric package. This Registration can be used to unregister callbacks. (#3522)
  • Global error handler uses an atomic value instead of a mutex. (#3543)
  • Add NewMetricProducer to go.opentelemetry.io/otel/bridge/opencensus, which can be used to pass OpenCensus metrics to an OpenTelemetry Reader. (#3541)
  • Global logger uses an atomic value instead of a mutex. (#3545)
  • The Shutdown method of the "go.opentelemetry.io/otel/sdk/trace".TracerProvider releases all computational resources when called the first time. (#3551)
  • The Sampler returned from TraceIDRatioBased go.opentelemetry.io/otel/sdk/trace now uses the rightmost bits for sampling decisions. This fixes random sampling when using ID generators like xray.IDGenerator and increasing parity with other language implementations. (#3557)
  • Errors from go.opentelemetry.io/otel/exporters/otlp/otlptrace exporters are wrapped in erros identifying their signal name. Existing users of the exporters attempting to identify specific errors will need to use errors.Unwrap() to get the underlying error. (#3516)
  • Exporters from go.opentelemetry.io/otel/exporters/otlp will print the final retryable error message when attempts to retry time out. (#3514)
  • The instrument kind names in go.opentelemetry.io/otel/sdk/metric are updated to match the API. (#3562)
    • InstrumentKindSyncCounter is renamed to InstrumentKindCounter
    • InstrumentKindSyncUpDownCounter is renamed to InstrumentKindUpDownCounter
    • InstrumentKindSyncHistogram is renamed to InstrumentKindHistogram
    • InstrumentKindAsyncCounter is renamed to InstrumentKindObservableCounter
    • InstrumentKindAsyncUpDownCounter is renamed to InstrumentKindObservableUpDownCounter
    • InstrumentKindAsyncGauge is renamed to InstrumentKindObservableGauge
  • The RegisterCallback method of the Meter in go.opentelemetry.io/otel/metric changed.
    • The named Callback replaces the inline function parameter. (#3564)
    • Callback is required to return an error. (#3576)
    • Callback accepts the added Observer parameter added. This new parameter is used by Callback implementations to observe values for asynchronous instruments instead of calling the Observe method of the instrument directly. (#3584)
    • The slice of instrument.Asynchronous is now passed as a variadic argument. (#3587)
  • 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)
  • The Min and Max fields of the HistogramDataPoint in go.opentelemetry.io/otel/sdk/metric/metricdata are now defined with the added Extrema type instead of a *float64. (#3487)

Fixed

  • Asynchronous instruments that use sum aggregators and attribute filters correctly add values from equivalent attribute sets that have been filtered. (#3439, #3549)
  • The RegisterCallback method of the Meter from go.opentelemetry.io/otel/sdk/metric only registers a callback for instruments created by that meter. Trying to register a callback with instruments from a different meter will result in an error being returned. (#3584)

  • The go.opentelemetry.io/otel/metric/instrument/syncint64 package is deprecated. Use the instruments from go.opentelemetry.io/otel/metric/instrument instead. (#3575)
  • The NewWrappedTracerProvider in go.opentelemetry.io/otel/bridge/opentracing is now deprecated. Use NewTracerProvider instead. (#3116)
