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:
{ const span = requestservertracer; const something = await ; span; 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()
