AWS::CloudWatch::Alarm does not work with AWS::ElasticLoadBalancing::LoadBalancer

[Bruno Bompastor]

Hi,

So as the title says these two resources are not working properly together.

Template to test: http://paste.openstack.org/show/A7AxbcQlLFuLCM8EBHYn/

Backtrace: http://paste.openstack.org/show/Ok096HUbM4Y8W0BT1HS8/

This should be related with several bugs opened concerning the "Dimensions" property on AWS alarm.

Adding the dimensions on engine/resources/loadbalancer.py makes it work:

    "latency_watcher": {
     "Type": "AWS::CloudWatch::Alarm",
     "Properties": {
        "MetricName": "Latency",
        "Namespace": "AWS/ELB",
        "Statistic": "Average",
        "Period": "60",
        "EvaluationPeriods": "1",
        "Threshold": "2",
        "AlarmActions": [],
        "Dimensions": [
          {
            "Name": "AlarmName",
            "Value": "latency_watcher"
          }
       ],
        "ComparisonOperator": "GreaterThanThreshold"
     }

Cheers,

Bruno Bompastor.

    Add Dimensions Default in AWS_CloudWatch_Alarm.yaml

    Relying on [1], property Dimensions isn't required, but
    this template has no Default value for Dimensions
    (thereby making it required). This patch fixes that omission.
    Besides that, parameters have wrong parsing, because if
    parameter with type 'CommaDelimitedList' has default
    value '', parameter's parsing result would be [u''] instead
    of []. this is wrong, so this patch fixes it.
