Aodh (and previously Ceilometer) doesn't know if it is calling Heat or not. It does an HTTP POST to whatever URL you specify as the alarm action. That's often the signal URL of the Heat scaling policy, but it doesn't have to be. And you can specify multiple actions, so you can notify Heat _and_ something else.

So can I execute a function in the alarm action? If it's possible how to do that

No, you can only POST to a URL.

Ok I understand, what about using a servlet?

Yes, you could definitely do that.

Could you more explain to me how to do it, what's the form of the url to use and should I put the servlet in the machine that contain openstack? How to call it?
