Exports data to a Zipkin back-end. By default, this exporter requires TLS and offers queued retry capabilities.

The following settings are required:

• endpoint (no default): URL to which the exporter is going to send Zipkin trace data.
• format (default = JSON): The format to sent events in. Can be set to JSON or proto.

By default, TLS is enabled and must be configured under tls::

• insecure (default = false): whether to enable client transport security for the exporter's connection.

As a result, the following parameters are also required under tls::

• cert_file (no default): path to the TLS cert to use for TLS required connections. Should only be used if insecure is set to false.
• key_file (no default): path to the TLS key to use for TLS required connections. Should only be used if insecure is set to false.

The following settings are optional:

• defaultservicename (default = <missing service name>): What to name services missing this information.

Example:

exporters:
  zipkin:
    endpoint: "http:https://some.url:9411/api/v2/spans"
    tls:
      cert_file: file.cert
      key_file: file.key
  zipkin/2:
    endpoint: "http:https://some.url:9411/api/v2/spans"
    tls:
      insecure: true

Several helper files are leveraged to provide additional capabilities automatically:

• HTTP settings
• TLS and mTLS settings
• Queuing, retry and timeout settings
