  # Should this be instrumented as a profile or layer?
  # If false, this operation will be instrumented as
  # a layer and layer_name should be provided.  If true,
  # layer_name is ignored.
  #
  # default: false
  profile: false

  # If this isn't a profile, this is the name that
  # the layer will show up at in the dashboard
  # If not specified, it will default to a Class#method string
  #
  # default: none
  layer_name: "sort"

  # Whether or not to collect and report a backtrace
  #
  # default: false
