Constructor Details

#initialize(set_endpoint_name: false) ⇒ SkylightTracing

Returns a new instance of SkylightTracing.

Parameters:

  • set_endpoint_name (Boolean) (defaults to: false) —

    If true, the GraphQL operation name will be used as the endpoint name. This is not advised if you run more than one query per HTTP request, for example, with graphql-client or multiplexing. It can also be specified per-query with context[:set_skylight_endpoint_name].
