io.opentelemetry.sdk.trace.export.MultiSpanExporter

All Implemented Interfaces:

SpanExporter

public final class MultiSpanExporter
extends Object
implements SpanExporter

Implementation of the SpanExporter that simply forwards all received spans to a list of SpanExporter.

Can be used to export to multiple backends using the same SpanProcessor like a SimpleSampledSpansProcessor or a BatchSampledSpansProcessor.

Method Detail

create

public static SpanExporter create(List<SpanExporter> spanExporters)

Constructs and returns an instance of this class.

Parameters:

spanExporters - the exporters spans should be sent to

Returns:

the aggregate span exporter

export

public io.opentelemetry.sdk.common.CompletableResultCode export(Collection<SpanData> spans)

Description copied from interface: SpanExporter

Called to export sampled Spans. Note that export operations can be performed simultaneously depending on the type of span processor being used. However, the BatchSpanProcessor will ensure that only one export can occur at a time.

Specified by:

export in interface SpanExporter

Parameters:

spans - the collection of sampled Spans to be exported.

Returns:

the result of the export, which is often an asynchronous operation.

flush

public io.opentelemetry.sdk.common.CompletableResultCode flush()

Flushes the data of all registered SpanExporters.

Specified by:

flush in interface SpanExporter

Returns:

the result of the operation

shutdown

public io.opentelemetry.sdk.common.CompletableResultCode shutdown()

Description copied from interface: SpanExporter

Called when TracerSdkManagement.shutdown() is called, if this SpanExporter is registered to a TracerSdkManagement object.

Specified by:

shutdown in interface SpanExporter

Returns:

a CompletableResultCode which is completed when shutdown completes.
