Package zipkin2.reporter.brave

Class ZipkinSpanHandler

java.lang.Object

brave.handler.SpanHandler

zipkin2.reporter.brave.ZipkinSpanHandler

All Implemented Interfaces:

Closeable

public class ZipkinSpanHandler
extends brave.handler.SpanHandler
implements Closeable

This allows you to send spans recorded by Brave to a pre-configured Zipkin reporter.

If you can't use AsyncZipkinSpanHandler because you are using an old format, construct the span handler like this:

 reporter = AsyncReporter.builder(URLConnectionSender.create("http://localhost:9411/api/v1/spans"))
                         .build(SpanBytesEncoder.JSON_V1);
 tracingBuilder.addSpanHandler(ZipkinSpanHandler.create(reporter));
 

Note: Use AsyncZipkinSpanHandler if you are using SpanBytesEncoder.JSON_V2 format. This handler has to convert MutableSpan into Span, and that conversion happens inline (during production requests) upon Span.finish() or Span.flush().

2.13

toBuilder

public ZipkinSpanHandler.Builder toBuilder()

Allows this instance to be reconfigured, for example ZipkinSpanHandler.Builder.alwaysReportSpans(boolean).

Note: Call close() if you no longer need this instance, as otherwise it can leak resources.
