new AsyncMetricStorage<T>(_instrumentDescriptor: InstrumentDescriptor, aggregator: Aggregator<T>, _attributesProcessor: AttributesProcessor, collectorHandles: MetricCollectorHandle[], _aggregationCardinalityLimit?: number): AsyncMetricStorage<T>

Overrides MetricStorage.constructor
- Defined in packages/sdk-metrics/src/state/AsyncMetricStorage.ts:42
Type Parameters
- T extends Maybe<Accumulation>
Parameters
- _instrumentDescriptor: InstrumentDescriptor
- aggregator: Aggregator<T>
- _attributesProcessor: AttributesProcessor
- collectorHandles: MetricCollectorHandle[]
- Optional _aggregationCardinalityLimit: number
Returns AsyncMetricStorage<T>

Properties

Protected _instrumentDescriptor

_instrumentDescriptor: InstrumentDescriptor

Methods

collect

collect(collector: MetricCollectorHandle, collectionTime: HrTime): Maybe<MetricData>

Overrides MetricStorage.collect
- Defined in packages/sdk-metrics/src/state/AsyncMetricStorage.ts:75
Collects the metrics from this storage. The ObservableCallback is invoked during the collection.

Note: This is a stateful operation and may reset any interval-related state for the MetricCollector.

Parameters
- collector: MetricCollectorHandle
- collectionTime: HrTime
Returns Maybe<MetricData>

getInstrumentDescriptor

getInstrumentDescriptor(): Readonly<InstrumentDescriptor>

Inherited from MetricStorage.getInstrumentDescriptor
- Defined in packages/sdk-metrics/src/state/MetricStorage.ts:45
Returns Readonly<InstrumentDescriptor>

record

record(measurements: AttributeHashMap<number>, observationTime: HrTime): void

Implementation of AsyncWritableMetricStorage.record
- Defined in packages/sdk-metrics/src/state/AsyncMetricStorage.ts:60
Records a batch of measurements.

Parameters
- measurements: AttributeHashMap<number>
- observationTime: HrTime
Returns void

updateDescription

updateDescription(description: string): void

Inherited from MetricStorage.updateDescription
- Defined in packages/sdk-metrics/src/state/MetricStorage.ts:49
Parameters
- description: string
Returns void
