2015-09-04 02:42:57 -0500 asked a question How to change default security group ?

I noticed when I create a project in OpenStack a default security group is automatically created. There are some defaults rules in it and I'd like to know how to change these rules to have "my own default security group" ?? because I don't want to create the same rules for each project

thanks for your help :)

Heat create 2 instances when the average CPU > 50% and if CPU stay above 50% my template still create instances. But when the average CPU < 20% heat delete only 1 instance after 5min and nothing more. Below 20% I'd like to delete 1 instance every 5 min not just 1. What's wrong on my template ?

For the realization of auto-scaling I made a template with heat and I've got e little problem. It works well but my heat template delete 1 instance after 5 minutes and not 1 instance every 5 minutes. How to do that ?

here is my tempalte.
