How does Heat set alarm configuration and get alarm back from Ceilometer?

Hi all,

I really need your helps. Currently, I am working on Heat auto-scaling. I already read some documents about auto-scaling in Heat. I know that Heat uses Ceilometer API to set alarm configuration and get alarm back from Ceilometer via Webhook. These actions are shown in HOT template (OS::Heat::Ceilometer::Alarm). I tried to look at Heat code but I still cannot get where (or what modules) handle alarm actions. In particularly:

  1. what module will be responsible for creating alarm url which then is received by Ceilometer
  2. what module will receive and handle alarm url triggered from Ceilometer.

Thanks
