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)
