      # Custom settings for instruments of a given category. The settings provided in this section override the default
      # and manually provided settings when creating instruments. All settings are optional in this section and default
      # values from the `kamon.metric.instrument-factory.default-settings` will be used in case of any setting being
      # missing.
      #
      # Example:
      # If you wish to change the highest trackable value setting of the `elapsed-time` instrument in the `span`
      # category, you should include the following configuration in your application.conf file:
      #
      #   kamon.metric.instrument-factory.custom-settings.span {
      #     elapsed-time {
      #       highest-trackable-value = 5000
      #     }
      #   }
      #
      # After including that configuration, every time a new histogram called `elapsed-time` for a entity with category
      # `span`, the highest-trackable-value will be 5000, but lowest-discernible-value and significant-value-digits will
      # remain with default values.
      #
      custom-settings {

      }
