    • evaluationPeriods

      @Stability(Stable) public CfnAlarm.Builder evaluationPeriods(Number evaluationPeriods)
      The number of periods over which data is compared to the specified threshold.

      If you are setting an alarm that requires that a number of consecutive data points be breaching to trigger the alarm, this value specifies that number. If you are setting an "M out of N" alarm, this value is the N, and DatapointsToAlarm is the M.

      For more information, see Evaluating an Alarm in the Amazon CloudWatch User Guide .

      Parameters:

    • alarmName

      @Stability(Stable) public CfnAlarm.Builder alarmName(String alarmName)
      The name of the alarm.

      If you don't specify a name, AWS CloudFormation generates a unique physical ID and uses that ID for the alarm name.

      If you specify a name, you cannot perform updates that require replacement of this resource. You can perform updates that require no or some interruption. If you must replace the resource, specify a new name.

    • datapointsToAlarm

      @Stability(Stable) public CfnAlarm.Builder datapointsToAlarm(Number datapointsToAlarm)
      The number of datapoints that must be breaching to trigger the alarm.

      This is used only if you are setting an "M out of N" alarm. In that case, this value is the M, and the value that you set for EvaluationPeriods is the N value. For more information, see Evaluating an Alarm in the Amazon CloudWatch User Guide .

      If you omit this parameter, CloudWatch uses the same value here that you set for EvaluationPeriods , and the alarm goes to alarm state if that many consecutive periods are breaching.

      Parameters:
