create

getAttributes

public io.opentelemetry.api.common.Attributes getAttributes(E1 dimension1,
 E2 dimension2,
 E3 dimension3)

record

public void record(double value,
 @Nonnull
 E1 dimension1,
 @Nonnull
 E2 dimension2,
 @Nonnull
 E3 dimension3)

Records a value for the given dimensions.

For MetricType.ASYNC_COUNTER_FOR_HIGH_PERF_CASES metrics, this uses the internal LongAdder for fast, contention-free recording. The accumulated value is read during OTel's collection callback.

For other metric types, this delegates to the parent class's record method.

record

public void record(long value,
 @Nonnull
 E1 dimension1,
 @Nonnull
 E2 dimension2,
 @Nonnull
 E3 dimension3)

getAllMetricAttributesData

protected Iterable<MetricAttributesData> getAllMetricAttributesData()

Description copied from class: MetricEntityState

Returns an iterable of all MetricAttributesData for observable counter reporting. Subclasses must implement this to provide iteration over their specific EnumMap structure. Returns null if metrics are not enabled or no data exists.

Specified by:

getAllMetricAttributesData in class MetricEntityState

getMetricAttributesDataEnumMap

public EnumMap<E1,EnumMap<E2,EnumMap<E3,MetricAttributesData>>> getMetricAttributesDataEnumMap()
