Hi, you may want to use the general mailing list for future usage questions
like this, as it's not really related to development:

https://wiki.openstack.org/wiki/Mailing_Lists#General_List

The answer to your question is you must create the alarm inside your heat
template, and reference a resource which provides a pre-signed URL, such as
a ScalingPolicy resource.

Here's an example template:

https://github.com/openstack/heat-templates/blob/master/hot/autoscaling.yaml#L121

If you really want to create the alarm via the ceilometer CLI for testing,
you'll need to expose the URL of the ScalingPolicy via a stack output, like
this:

https://github.com/openstack/heat-templates/blob/master/hot/asg_of_servers.yaml#L78

And get the output URL via "heat stack-show <stack name>"
