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

record

record(value: number, attributes: Attributes, context: Context, recordTime: HrTime): void

Implementation of WritableMetricStorage.record
- Defined in packages/sdk-metrics/src/state/SyncMetricStorage.ts:59
Records a measurement.

Parameters
- value: number
- attributes: Attributes
- context: Context
- recordTime: 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
