Open Stack

Hello all,
I am running Havana on Ubuntu 12.04.  I have created a template which creates a stack that autoscales based on cpu utilization. I am able to successfully create the stack thru Horizon by importing a template that I have created. The problem is my alarm action is not working properly. In the ceiloemeter-alarm-notifier log I am seeing the following errror:  2014-03-27 21:56:14.617 11258 ERROR ceilometer.alarm.service [req-94c6c466-760d-4b63-a186-a994bcb881ce None None] Action  for alarm 636a4dc3-a15d-4093-97a8-d4e9f6c50cf4 is unknown, cannot notifyIt appears that this is the code from service.py that is generating the error in the logfile:try:
            notifier = self.notifiers[action.scheme].obj
        except KeyError:
            scheme = action.scheme
            LOG.error(
                _("Action %(scheme)s for alarm %(alarm_id)s is unknown, "
                  "cannot notify"),
                {'scheme': scheme, 'alarm_id': alarm_id})
            returnI freely admit I am no python expert and was able to find this bit of code thru some searching of the repository.My Template is as follows:   HeatTemplateFormatVersion: '2012-12-12'
