Question

Cloudformation堆栈在使用cloudformation创建AWS :: CloudWatch :: Alarm时抛出错误“遇到不受支持的属性比较运算符” 。

根据AWS文档 ComparisionOperator 值 GreaterThanOrEqualtoThreshold 是有效的。我将AWSTemplateFormatVersion用作 2010-09-09

任何帮助将不胜感激：）

"CPUHighAlarm":{
            "Type":"AWS::CloudWatch::Alarm",
            "Properties":{
                "AlarmDescription":"High CPU utilization",
                "MetricName":"CPUUtilization",
                "Namespace":"AWS/EC2",
                "AlarmActions":[{"Ref":"asgScaleOut"}],
                "ComparisionOperator": "GreaterThanOrEqualtoThreshold",
                "EvaluationPeriods": "1",
                "Threshold": "70",
                "Period":"180",
                "Statistic": "Average",
                "Dimensions": [
                    {
                        "Name": "AutoScalingGroupName",
                        "Value": {
                            "Ref": "asg"
                        }
                    }
                ]
            }
        },

Answer 1

也许是区分大小写的。尝试GreaterThanOrEqualToThreshold。

Answer 2

只是一个错字。应该是ComparisonOperator而不是ComparisionOperator。

CloudFormation Linter可以帮助您更快地捕获这些错误，而Visual Studio Code extension可以通过自动完成功能来防止错别字：

E3002: Invalid Property Resources/CPUHighAlarm/Properties/ComparisionOperator

遇到不受支持的属性CompareOperator
