Interface PushMetricExporter

An interface that allows different metric services to export recorded data in their own format.

To export data this MUST be registered to the Metrics SDK with a MetricReader.

interface PushMetricExporter {
    export(
        metrics: ResourceMetrics,
        resultCallback: (result: core.ExportResult) => void,
    ): void;
    forceFlush(): Promise<void>;
    selectAggregation?(instrumentType: InstrumentType): AggregationOption;
    selectAggregationTemporality?(
        instrumentType: InstrumentType,
    ): AggregationTemporality;
    shutdown(): Promise<void>;
}

Methods

export

export(
metrics: ResourceMetrics,
resultCallback: (result: core.ExportResult) => void,
): void
Called to export sampled ResourceMetrics.
Parameters
- metrics: ResourceMetrics
  the metric data to be exported.
- resultCallback: (result: core.ExportResult) => void
  callback for when the export has completed
Returns void
- Defined in packages/sdk-metrics/src/export/MetricExporter.ts:23

forceFlush

forceFlush(): Promise<void>
Ensure that the export of any metrics the exporter has received is completed before the returned promise is settled.

Returns Promise<void>
- Defined in packages/sdk-metrics/src/export/MetricExporter.ts:32

`Optional`selectAggregation

selectAggregation?(instrumentType: InstrumentType): AggregationOption
Select the Aggregation for the given InstrumentType for this exporter.
Parameters
- instrumentType: InstrumentType
Returns AggregationOption
- Defined in packages/sdk-metrics/src/export/MetricExporter.ts:46

`Optional`selectAggregationTemporality

selectAggregationTemporality?(
instrumentType: InstrumentType,
): AggregationTemporality
Select the AggregationTemporality for the given InstrumentType for this exporter.
Parameters
- instrumentType: InstrumentType
Returns AggregationTemporality
- Defined in packages/sdk-metrics/src/export/MetricExporter.ts:38

shutdown

shutdown(): Promise<void>
Returns a promise which resolves when the last exportation is completed. Further calls to PushMetricExporter.export may not export the data.

Returns Promise<void>
- Defined in packages/sdk-metrics/src/export/MetricExporter.ts:53
