      # This Rubocop will check for providing the value for a metric using a keyword argument, which is
      # deprecated. Use the following Rubocop invocation to check your project's codebase:
      #
      #    rubocop --require \
      #      `bundle show statsd-instrument`/lib/statsd/instrument/rubocop.rb \
      #      --only StatsD/MetricValueKeywordArgument

      # This cop will not autocorrect offenses. Most of the time, these are easy to fix by providing the
      # value as the second argument, rather than a keyword argument.
      #
      # `StatsD.increment('foo', value: 3)` => `StatsD.increment('foo', 3)`

          Do not use the StatsD.metric('name', value: <value>, ...). The `value` keyword argument is deprecated.

          Use a positional argument instead: StatsD.metric('name', <value>, ...).
