Constructor Details

#initialize(options = {}) ⇒ SkylightTracing

Returns a new instance of SkylightTracing.

Parameters:

  • set_endpoint_name (Boolean)

    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].
