Options for the AT_LEAST AlarmRule wrapper function.

Example

declare const alarm1: cloudwatch.Alarm;
declare const alarm2: cloudwatch.Alarm;
declare const alarm3: cloudwatch.Alarm;
declare const alarm4: cloudwatch.Alarm;

const alarmRule = cloudwatch.AlarmRule.anyOf(

      cloudwatch.AlarmRule.fromAlarm(alarm2, cloudwatch.AlarmState.OK),
      alarm3,
    ),
    cloudwatch.AlarmRule.not(cloudwatch.AlarmRule.fromAlarm(alarm4, cloudwatch.AlarmState.INSUFFICIENT_DATA)),
    // AT_LEAST with count: at least 2 of these alarms must be in ALARM state
    cloudwatch.AlarmRule.atLeast(cloudwatch.AlarmState.ALARM, {
      operands: [alarm1, alarm2, alarm3],
      threshold: cloudwatch.AtLeastThreshold.count(2),
    }),
    // AT_LEAST with percentage and NOT: at least 60% must NOT be in OK state
