Get answers to your questions about Wavefront distributed tracing

This page has some special tips to help you instrument your applications and send trace data to Wavefront.

How do I send custom span level RED metrics?

For details on how to send span-level RED metrics using a custom tracing port, see Instrument Your Application with Wavefront Sender SDKs.

How do I filter RED metrics using custom span tags?

If you want to filter RED metrics data using a non-default span tag, propagate the tag as a custom span tag to the RED metrics. See Custom Span-Level Tags for RED Metrics.

How do I customize the application name (Zipkin or Jaeger)?

To override the default application name when using zipkin-js, OpenTracing Zipkin/Jaeger libraries, or OpenTelemetry Zipkin/Jaeger libraries, use any of the following options:

  • Add the following span tag to the application logic.
  • If you are using the Wavefront proxy and don’t want to modify your code, open the <wavefront_config_path>/wavefront.conf file, and update or add the following configuration.
    • Zipkin
      traceZipkinApplicationName = <Enter_Application_Name>
    • Jaeger
      traceJaegerApplicationName = <Enter_Application_Name>

How do I emit spans in the Wavefront format?

If you are not using a Wavefront SDK, OpenTracing library, or OpenTelemetry library, you can still send spans to Wavefront using the Wavefront proxy.

Send spans to the Wavefront proxy’s customTracingListenerPorts port in the Wavefront spans format. Open the <wavefront_config_path>/wavefront.conf file, and update or add the customTracingListenerPorts property.

Given below is an example of the Wavefront span format:

wavefrontSender.sendSpan("getAllUsers", System.currentTimeMillis(), 343, "localhost",
        "2f64e538-9457-11e8-9eb6-529269fb1459")).build(), null,
      ImmutableList.<Pair<String, String>>builder().
        add(new Pair<>("application", "Wavefront")).
        add(new Pair<>("service", "myService")).
        add(new Pair<>("http.method", "GET")).build(), null);
