Hi ,
as I wanted to check out the autoscaling features of heat in combination with
ceilometer, I tried to adapt one of the example HOT's. Meanwhile, the HOT is
starting successfully, but whatever I do to stress my VM in the
web_server_group, no scaling reaction is observable.
Executing the webhook manually, there's an error response, which google hardly
knows, so I try my best here - maybe you can help me to solve this problem.
Additionally I'm wondering, why AWS is mentioned in the error - actually I
don't want to use it. Are webhooks only possible via AWS?
root@build-server:~# ceilometer alarm-show -a
