    Properties

    Decorates the hapi server object with .tracer, which is an instance of the intialized Tracer class. This can be used to create spans and reports. To access a parent span of one of the following types you can use the new request.span(type) method to return the current span of whatever type you care about. For example, to create a new span in a request handler using the parent handler span you can invoke request.span as follows:

    handler: (request, h) => {
      const span = request.server.tracer.startSpan('some_action', { childOf: request.span('handler').context() });
      const something = await someAction();
      span.finish();
      return something;
    }

    The following spans are created:

    • hapi_request
    • hapi_auth
    • hapi_handler
    • hapi_response
    • hapi_log

    Inside of a handler you can obtain the parent span by invoking request.span()
