Package io.opentelemetry.sdk.metrics.export

Interface MetricExporter

All Known Implementing Classes:
InMemoryMetricExporter
public interface MetricExporter
MetricExporter is the interface that all "push based" metric libraries should use to export metrics to the OpenTelemetry exporters.

All OpenTelemetry exporters should allow access to a MetricExporter instance.

  • Method Summary

    Modifier and Type
    Method
    Description
    io.opentelemetry.sdk.common.CompletableResultCode
    export(Collection<MetricData> metrics)
    Exports the collection of given MetricData.
    io.opentelemetry.sdk.common.CompletableResultCode
    flush()
    Exports the collection of MetricData that have not yet been exported.
    default AggregationTemporality
    getPreferredTemporality()
    Returns the preferred temporality for metrics.
    io.opentelemetry.sdk.common.CompletableResultCode
    shutdown()
    Called when the associated IntervalMetricReader is shutdown.

  • Method Details

    • getPreferredTemporality

      @Nullable default AggregationTemporality getPreferredTemporality()
      Returns the preferred temporality for metrics.

    • export

      io.opentelemetry.sdk.common.CompletableResultCode export(Collection<MetricData> metrics)
      Exports the collection of given MetricData. Note that export operations can be performed simultaneously depending on the type of metric reader being used. However, the caller MUST ensure that only one export can occur at a time.
      Parameters:
      metrics - the collection of MetricData to be exported.
      Returns:
      the result of the export, which is often an asynchronous operation.

    • flush

      io.opentelemetry.sdk.common.CompletableResultCode flush()
      Exports the collection of MetricData that have not yet been exported. Note that flush operations can be performed simultaneously depending on the type of metric reader being used. However, the caller MUST ensure that only one export can occur at a time.
      Returns:
      the result of the flush, which is often an asynchronous operation.

    • shutdown

      io.opentelemetry.sdk.common.CompletableResultCode shutdown()
      Called when the associated IntervalMetricReader is shutdown.
      Returns:
      a CompletableResultCode which is completed when shutdown completes.
