Using dynamic inventory with ec2.py am trying to filter based on all instance **except** where the security group is monolithic.

I tried:

> instance\_filters = !security\_group:monolithic

But this did not work. How is this possible?

Also tried:

instance\_filters = instance.group-name!=monolithic

Anybody know how to negate filter?
