Hi , I have installed openstack nova,neutron,glance,keystone,tacker,ceilometer,aodh for newton version from the official openstack installation site. I am trying to perform scaling and orchestration using tacker,ceilometer,aodh . I am trying to create vnf with scaling condition such that :

i) If cpu utilisation higher than threshold then VNF should scale-out.

ii)if cpu utilisation less than threshold then VNF should scale-in.

For this I have used Tacker's TOSCA scaling template reference. However if I mention the above two conditions in VNF Descriptor , the 2nd condition overwrites condition 1 . I imply this because aodh shows only 1 alarm with 2nd condition. Testing with less CPU utilisation also gave same output. What can I do so that both condition should co-exist in VNF Descriptor and there is no overwriting?
