[Openstack] Autoscaling : heat stack failed

Are you using Neutron? Is this your first time with Neutron? When I
switched from nova networking to Neutron I was initially surprised by
errors with the same text. For me it was when creating VM instances. Can
you make a load balancer using the CLI?
Note that the log excerpt you show is telling you that what is being
raised is an error that arose earlier and was cached. Look for the
earlier error. The root cause may be found in the log of a different
component.
Regards,
Mike

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

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 05:37:50.203 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"
# "AWS::CloudWatch::Alarm": "OS::Heat::CWLiteAlarm"
"OS::Metering::Alarm": "OS::Ceilometer::Alarm"
# "AWS::RDS::DBInstance": "
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
