Instance Method Details

#add_span_processor(span_processor) ⇒ Object

Add a span processor to the export pipeline

Parameters:

  • span_processor (#on_start, #on_finish, #shutdown, #force_flush) —

    A span_processor that satisfies the duck type #on_start, #on_finish, #shutdown, #force_flush. See SimpleSpanProcessor for an example.

  @span_processors << span_processor
end

#configure ⇒ Object

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

The configure method is where we define the setup process. This allows us to make certain guarantees about which systems and globals are setup at each stage. The setup process is: - setup logging - setup propagation - setup tracer_provider and meter_provider - install instrumentation

  OpenTelemetry.logger = logger
  OpenTelemetry.baggage = Baggage::Manager.new
  configure_propagation
  configure_span_processors
  OpenTelemetry.tracer_provider = tracer_provider
  install_instrumentation
end

#resource=(new_resource) ⇒ Object

Accepts a resource object that is merged with the default telemetry sdk resource. The use of this method is optional, and is provided as means to include additional resource information. If a resource key collision occurs the passed in resource takes priority.

Parameters:

  • new_resource (Resource) —

    The resource to be merged

def resource=(new_resource)
  @resource = new_resource.merge(@resource)
end

#service_name=(service_name) ⇒ Object

Accepts a string that is merged in as the service.name resource attribute. The most recent assigned value will be used in the event of repeated calls to this setter.

Parameters:

  • service_name (String) —

    The value to be used as the service name

    OpenTelemetry::SDK::Resources::Constants::SERVICE_RESOURCE[:name] => service_name
  ).merge(@resource)
end

#service_version=(service_version) ⇒ Object

Accepts a string that is merged in as the service.version resource attribute. The most recent assigned value will be used in the event of repeated calls to this setter.

Parameters:

  • service_version (String) —

    The value to be used as the service version

  ).merge(@resource)
end

#use(instrumentation_name, config = nil) ⇒ Object

Install an instrumentation with specificied optional config. Use can be called multiple times to install multiple instrumentation. Only use or use_all, but not both when installing instrumentation. A call to use_all after use will result in an exception.

Parameters:

  • instrumentation_name (String) —

    The name of the instrumentation

  • config (optional Hash) (defaults to: nil) —

    The config for this instrumentation

  @instrumentation_names << instrumentation_name
  @instrumentation_config_map[instrumentation_name] = config if config
end

#use_all(instrumentation_config_map = {}) ⇒ Object

Install all registered instrumentation. Configuration for specific instrumentation can be provided with the optional instrumentation_config_map parameter. Only use or use_all, but not both when installing instrumentation. A call to use after use_all will result in an exception.

Parameters:

  • instrumentation_config_map (optional Hash<String,Hash>) (defaults to: {}) —

    A map with string keys representing the instrumentation name and values specifying the instrumentation config
