  • 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 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)

v1.11.1: /v0.33.0

Compare Source

Added

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)

• Add the metric/global for obtaining and setting the global MeterProvider. (#​2660)

Changed

• The metrics API has been significantly changed to match the revised OpenTelemetry specification.
  High-level changes include:

  • Synchronous and asynchronous instruments are now handled by independent InstrumentProviders.
    These InstrumentProviders are managed with a Meter.
  • Synchronous and asynchronous instruments are grouped into their own packages based on value types.
  • Asynchronous callbacks can now be registered with a Meter.

  Be sure to check out the metric module documentation for more information on how to use the revised API. (#​2587, #​2660)

Fixed

• Fallback to general attribute limits when span specific ones are not set in the environment. (#​2675, #​2677)

v1.5.0

Compare Source

Added

• Log the Exporters configuration in the TracerProviders message. (#​2578)
• Added support to configure the span limits with environment variables.
  The following environment variables are supported. (#​2606, #​2637)
  • OTEL_SPAN_ATTRIBUTE_VALUE_LENGTH_LIMIT
  • OTEL_SPAN_ATTRIBUTE_COUNT_LIMIT
  • OTEL_SPAN_EVENT_COUNT_LIMIT
  • OTEL_EVENT_ATTRIBUTE_COUNT_LIMIT
  • OTEL_SPAN_LINK_COUNT_LIMIT
  • OTEL_LINK_ATTRIBUTE_COUNT_LIMIT
    If the provided environment variables are invalid (negative), the default values would be used.
• Rename the gc runtime name to go (#​2560)
• Add resource container ID detection. (#​2418)
• Add span attribute value length limit.
  The new AttributeValueLengthLimit field is added to the "go.opentelemetry.io/otel/sdk/trace".SpanLimits type to configure this limit for a TracerProvider.
  The default limit for this resource is "unlimited". (#​2637)
• Add the WithRawSpanLimits option to go.opentelemetry.io/otel/sdk/trace.
  This option replaces the WithSpanLimits option.
  Zero or negative values will not be changed to the default value like WithSpanLimits does.
  Setting a limit to zero will effectively disable the related resource it limits and setting to a negative value will mean that resource is unlimited.
  Consequentially, limits should be constructed using NewSpanLimits and updated accordingly. (#​2637)

Changed

• Drop oldest tracestate Member when capacity is reached. (#​2592)
• Add event and link drop counts to the exported data from the oltptrace exporter. (#​2601)
• Unify path cleaning functionally in the otlpmetric and otlptrace configuration. (#​2639)
• Change the debug message from the sdk/trace.BatchSpanProcessor to reflect the count is cumulative. (#​2640)
• Introduce new internal envconfig package for OTLP exporters. (#​2608)
• If http.Request.Host is empty, fall back to use URL.Host when populating http.host in the semconv packages. (#​2661)

Fixed

• Remove the OTLP trace exporter limit of SpanEvents when exporting. (#​2616)
• Default to port 4318 instead of 4317 for the otlpmetrichttp and otlptracehttp client. (#​2614, #​2625)
• Unlimited span limits are now supported (negative values). (#​2636, #​2637)

Deprecated

• Deprecated "go.opentelemetry.io/otel/sdk/trace".WithSpanLimits.
  Use WithRawSpanLimits instead.
  That option allows setting unlimited and zero limits, this option does not.
  This option will be kept until the next major version incremented release. (#​2637)

v1.4.1

Compare Source

Fixed

• Fix race condition in reading the dropped spans number for the BatchSpanProcessor. (#​2615)

v1.4.0: /v0.27.0

Compare Source

Added

• Use OTEL_EXPORTER_ZIPKIN_ENDPOINT environment variable to specify zipkin collector endpoint. (#​2490)
• Log the configuration of TracerProviders, and Tracers for debugging.
  To enable use a logger with Verbosity (V level) >=1. (#​2500)
• Added support to configure the batch span-processor with environment variables.
  The following environment variables are used. (#​2515)
  • OTEL_BSP_SCHEDULE_DELAY
  • OTEL_BSP_EXPORT_TIMEOUT
  • OTEL_BSP_MAX_QUEUE_SIZE.
  • OTEL_BSP_MAX_EXPORT_BATCH_SIZE

Changed

• Zipkin exporter exports Resource attributes in the Tags field. (#​2589)

Deprecated

• Deprecate module the go.opentelemetry.io/otel/sdk/export/metric.
  Use the go.opentelemetry.io/otel/sdk/metric module instead. (#​2382)
• Deprecate "go.opentelemetry.io/otel/sdk/metric".AtomicFieldOffsets. (#​2445)

Fixed

• Fixed the instrument kind for noop async instruments to correctly report an implementation. (#​2461)
• Fix UDP packets overflowing with Jaeger payloads. (#​2489, #​2512)
• Change the otlpmetric.Client interface's UploadMetrics method to accept a single ResourceMetrics instead of a slice of them. (#​2491)
• Specify explicit buckets in Prometheus example, fixing issue where example only has +inf bucket. (#​2419, #​2493)
• W3C baggage will now decode urlescaped values. (#​2529)
• Baggage members are now only validated once, when calling NewMember and not also when adding it to the baggage itself. (#​2522)
• The order attributes are dropped from spans in the go.opentelemetry.io/otel/sdk/trace package when capacity is reached is fixed to be in compliance with the OpenTelemetry specification.
  Instead of dropping the least-recently-used attribute, the last added attribute is dropped.
  This drop order still only applies to attributes with unique keys not already contained in the span.
  If an attribute is added with a key already contained in the span, that attribute is updated to the new value being added. (#​2576)

Removed

• Updated go.opentelemetry.io/proto/otlp from v0.11.0 to v0.12.0. This version removes a number of deprecated methods. (#​2546)
  • Metric.GetIntGauge()
  • Metric.GetIntHistogram()
  • Metric.GetIntSum()
