Hi Team,
This is the last error I received after modifying in ElasticLoadBalancer

Hi Team,
I fixed the earlier error and landed at below error

I have mentioned my network details in my template.

Do I need to mention it somewhere in load balancer as well ?...?

Subject: Autoscaling : heat stack failed
Hello All,
I have configured openstack Havana on Ubuntu 12.04 . I configured heat & ceilometer.
When I was creating stack I found that stack creation failed in log
2014-03-21 05:37:50.170 22127 TRACE heat.engine.resource raise exception.StackValidationFailed(message=msg)
2014-03-21 05:37:50.170 22127 TRACE heat.engine.resource StackValidationFailed: Unknown resource Type : AWS::CloudWatch::Alarm
2014-03-21 05:37:50.170 22127 TRACE heat.engine.resource
2014-03-21 05:37:50.203 22127 WARNING heat.engine.service [-] Stack create failed, status FAILED
So I added default.yaml in /etc/ceilometer/environment.d/
resource_registry:
# allow older templates with Quantum in them.
"OS::Quantum*": "OS::Neutron*"
# Choose your implementation of AWS::CloudWatch::Alarm
#"AWS::CloudWatch::Alarm": "file:///etc/heat/templates/AWS_CloudWatch_Alarm.yaml<file:///\\etc\heat\templates\AWS_CloudWatch_Alarm.yaml>"
# "AWS::CloudWatch::Alarm": "OS::Heat::CWLiteAlarm"
"OS::Metering::Alarm": "OS::Ceilometer::Alarm"
# "AWS::RDS::DBInstance": "file:///etc/heat/templates/AWS_RDS_DBInstance.yaml<file:///\\etc\heat\templates\AWS_RDS_DBInstance.yaml>"
# "AWS::CloudWatch::Alarm": "OS::Ceilometer::Alarm"
If I remove the comment from # "AWS::CloudWatch::Alarm": "OS::Heat::CWLiteAlarm" , restarted my heat services . If I try to create a stack it shows below error
