forService

public static ZipkinTracerBuilder forService(java.lang.String serviceName)

Get a Zipkin Tracer builder for processing tracing data of a service with a given name.

Parameters:

serviceName - name of the service that will be using the tracer.

Returns:

Tracer builder for Zipkin.

version

public ZipkinTracerBuilder version(ZipkinTracerBuilder.Version version)

Version of Zipkin API to use. Defaults to ZipkinTracerBuilder.Version.V2.

Parameters:

version - version to use

Returns:

updated builder instance

path

public ZipkinTracerBuilder path(java.lang.String path)

Override path to use. Path is usually defined by the protocol ZipkinTracerBuilder.Version. Use this to override if not using default (e.g. when Zipkin is behind a reverse proxy that prefixes the path).

Parameters:

path - path to override the default defined by ZipkinTracerBuilder.Version

Returns:

updated builder instance

from

public static ZipkinTracerBuilder from(Config config)

Create a new builder based on values in configuration. This requires at least a key "service" in the provided config.

Parameters:

config - configuration to load this builder from

Returns:

a new builder instance.

fromConfig(Config)

fromConfig

public ZipkinTracerBuilder fromConfig(Config config)

Update this builder from configuration.

Parameters:

config - configuration that contains at least the key service (if using configuration only).

Returns:

updated builder instance

zipkin

public ZipkinTracerBuilder zipkin(java.net.URI endpoint)

Set the Zipkin endpoint address.

The resulting Tracer will be sending any tracing data to this location. The significant parts of the URI are userInfo, host and port. Other parts of the endpoint URI are ignored.

Parameters:

endpoint - Zipkin endpoint address. Must not be null.

Returns:

updated builder.

zipkin

public ZipkinTracerBuilder zipkin(java.lang.String endpoint)

Set the Zipkin endpoint address.

The resulting Tracer will be sending any tracing data to this location. The significant parts of the endpoint URI are userInfo, host and port. Other parts of the endpoint URI are ignored.

Parameters:

endpoint - Zipkin endpoint address. May be null, in which case the default Zipkin endpoint address will be used (http://127.0.0.1:9411/).

Returns:

updated builder.

zipkinHost

public ZipkinTracerBuilder zipkinHost(java.lang.String hostName)

Set the Zipkin host name.

The resulting Tracer will be sending any tracing data to the Zipkin location address constructed using the supplied host name and the default Zipkin port (i.e. http://<hostName>:9411/).

Parameters:

hostName - Zipkin host name.

Returns:

updated builder.

protocol

public ZipkinTracerBuilder protocol(java.lang.String protocol)

Set the protocol to use (http, https). Defaults to .

Parameters:

Parameters:

sender - the sender to use

Returns:

this builder
