Question

这是AWS document中CloudFormation警报的结构。

Type: "AWS::CloudWatch::Alarm"
Properties:
  ActionsEnabled: Boolean
  AlarmActions:
    - String
  AlarmDescription: String
  AlarmName: String
  ComparisonOperator: String
  Dimensions:
    - Dimension
  EvaluateLowSampleCountPercentile: String
  EvaluationPeriods: Integer
  ExtendedStatistic: String
  InsufficientDataActions:
    - String
  MetricName: String
  Namespace: String
  OKActions:
    - String
  Period: Integer
  Statistic: String
  Threshold: Double
  TreatMissingData: String
  Unit: String

但是，似乎为lambda函数总数指标设置了警报，而不仅仅是为特定功能设置了警报，我找不到提及为特定功能设置警报的信息。

如何设置特定功能的警报？

Answer 1

要对特定的lambda函数的度量标准发出警报，您必须设置FunctionName维度。

例如：

  MyNewAlarm:
    Type: AWS::CloudWatch::Alarm
    Properties:
      AlarmName: "AlarmNameGoesHere"
      AlarmDescription: "Alarm if lambda errors out too many times"
      Namespace: "AWS/Lambda"
      MetricName: "Errors"
      Dimensions:
      - Name: "FunctionName"
        Value: "NameOfYourLambdaFunction"
      Statistic: "Sum"
      ComparisonOperator: "GreaterThanThreshold"
      Threshold: 0
      EvaluationPeriods: 5
      Period: 60
      TreatMissingData: "breaching"
