Release Notes

open-telemetry/opentelemetry-rust (opentelemetry)

v0.30.0

Compare Source

Released 2025-May-23

#​2821 Context
based suppression capabilities added: Added the ability to prevent recursive
telemetry generation through new context-based suppression mechanisms. This
feature helps prevent feedback loops and excessive telemetry when OpenTelemetry
components perform their own operations.

New methods added to Context:

• is_telemetry_suppressed() - Checks if telemetry is suppressed in this
  context
• with_telemetry_suppressed() - Creates a new context with telemetry
  suppression enabled
• is_current_telemetry_suppressed() - Efficiently checks if the current thread's context
  has telemetry suppressed
• enter_telemetry_suppressed_scope() - Convenience method to enter a scope where telemetry is
  suppressed

These methods allow SDK components, exporters, and processors to temporarily
disable telemetry generation during their internal operations, ensuring more
predictable and efficient observability pipelines.

• re-export tracing for internal-logs feature to remove the need of adding tracing as a dependency

open-telemetry/opentelemetry-rust (opentelemetry_sdk)

v0.30.0

Compare Source

Released 2025-May-23

• Updated opentelemetry and opentelemetry-http dependencies to version 0.30.0.

• It is now possible to add links to a Span via the SpanRef that you get from
  a Context. 2959

• Feature: Added context based telemetry suppression. #​2868

  • SdkLogger, SdkTracer modified to respect telemetry suppression based on
    Context. In other words, if the current context has telemetry suppression
    enabled, then logs/spans will be ignored.
  • The flag is typically set by OTel
    components to prevent telemetry from itself being fed back into OTel.
  • BatchLogProcessor, BatchSpanProcessor, and PeriodicReader modified to set
    the suppression flag in their dedicated thread, so that telemetry generated from
    those threads will not be fed back into OTel.
  • Similarly, SimpleLogProcessor
    also modified to suppress telemetry before invoking exporters.

• Feature: Implemented and enabled cardinality capping for Metrics by
  default. #​2901

  • The default cardinality limit is 2000 and can be customized using Views.
  • This feature was previously removed in version 0.28 due to the lack of
    configurability but has now been reintroduced with the ability to configure
    the limit.
  • Fixed the overflow attribute to correctly use the boolean value true
    instead of the string "true".
    #​2878

• The shutdown_with_timeout method is added to SpanProcessor, SpanExporter trait and TracerProvider.

• The shutdown_with_timeout method is added to LogExporter trait.

• The shutdown_with_timeout method is added to LogProvider and LogProcessor trait.

• Breaking MetricError, MetricResult no longer public (except when
  spec_unstable_metrics_views feature flag is enabled). OTelSdkResult should
  be used instead, wherever applicable. #​2906

• Breaking change, affecting custom MetricReader authors:

  • The
    shutdown_with_timeout method is added to MetricReader trait.
  • collect
    method on MetricReader modified to return OTelSdkResult.
    #​2905
  • MetricReader
    trait, ManualReader struct, Pipeline struct, InstrumentKind enum moved
    behind feature flag "experimental_metrics_custom_reader".
    #​2928

• Views improvements:

  • Core view functionality is now available by default—users can change the
    name, unit, description, and cardinality limit of a metric via views without
    enabling the spec_unstable_metrics_views feature flag. Advanced view
    features, such as custom aggregation or attribute filtering, still require
    the spec_unstable_metrics_views feature.
  • Removed new_view() method and View trait. Views can now be added by passing
    a function with signature Fn(&Instrument) -> Option<Stream> to the with_view
    method on MeterProviderBuilder.

• Introduced a builder pattern for Stream creation to use with views:

  • Added StreamBuilder struct with methods to configure stream properties
  • Added Stream::builder() method that returns a new StreamBuilder
  • StreamBuilder::build() returns Result<Stream, Box<dyn Error>> enabling
    proper validation.

Example of using views to rename a metric:

let view_rename = |i: &Instrument| {
    if i.name() == "my_histogram" {
        Some(
            Stream::builder()
                .with_name("my_histogram_renamed")
                .build()
                .unwrap(),
        )
    } else {
        None
    }
};

let provider = SdkMeterProvider::builder()
    // add exporters, set resource etc.
    .with_view(view_rename)
    .build();

• Breaking Aggregation enum moved behind feature flag
  "spec_unstable_metrics_views". This was only required when using advanced view
  capabilities.
  #​2928
• Breaking change, affecting custom PushMetricExporter authors:
  • The export method on PushMetricExporter now accepts &ResourceMetrics
    instead of &mut ResourceMetrics.
  • ResourceMetrics no longer exposes scope_metrics field, but instead
    offers scope_metrics() method that returns an iterator over the same.
  • ScopeMetrics no longer exposes metrics field, but instead offers
    metrics() method that returns an iterator over the same.
  • Sum, Gauge, Histogram & ExponentialHistogram no longer exposes
    data_points field, but instead offers data_points() method that returns
    an iterator over the same.
  • SumDataPoint, GaugeDataPoint, HistogramDataPoint &
    ExponentialHistogramDataPoint no longer exposes attributes, exemplars
    field, but instead offers attributes(), and exemplars() method that
    returns an iterator over the same.
  • Exemplar no longer exposes filtered_attributes field, but instead
    offers filtered_attributes() method that returns an iterator over
    the same.
  • HistogramDataPoint no longer exposes bounds and bucket_counts, but
    instead offers bounds() and bucket_counts() methods that returns an
    iterator over the same.
  • Metric no longer exposes name, description, unit, data fields, but
    instead offers name(), description(), unit(), and data() accessor methods.
  • ResourceMetrics no longer exposes resource field, but instead offers
    a resource() accessor method.
  • ScopeMetrics no longer exposes scope field, but instead offers
    a scope() accessor method.
