Class with static functions to build AlarmRule for Composite Alarms.

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.allOf(
    cloudwatch.AlarmRule.anyOf(
      alarm1,
      cloudwatch.AlarmRule.fromAlarm(alarm2, cloudwatch.AlarmState.OK),
      alarm3,
    ),
    cloudwatch.AlarmRule.not(cloudwatch.AlarmRule.fromAlarm(alarm4, cloudwatch.AlarmState.INSUFFICIENT_DATA)),
  ),
  cloudwatch.AlarmRule.fromBoolean(false),
);

new cloudwatch.CompositeAlarm(this, 'MyAwesomeCompositeAlarm', {
  alarmRule,
});

Initializer

new AlarmRule()
