[Gábor Antal]

In watcher/common/ceilometer_help.py:129, there is an unused parameter in
  def get_last_sample_values(self, resource_id, meter_name, limit=1):

We should remove that

    Pass parameter to the query in get_last_sample_values

    In watcher/common/ceilometer_help.py:129,
    there is an unused parameter, called limit:
      def get_last_sample_values(self, resource_id, meter_name, limit=1):

    In the next line, there is a method call which can take this
    currently unused 'limit' parameter. Probably, passing this 'limit'
    parameter to the query was originally intended, however it wasn't
    added to the query call.
