# AWS::ARCZonalShift::ZonalAutoshiftConfiguration ControlCondition
<a name="aws-properties-arczonalshift-zonalautoshiftconfiguration-controlcondition"></a>

A control condition is an alarm that you specify for a practice run. When you configure practice runs with zonal autoshift for a resource, you specify Amazon CloudWatch alarms, which you create in CloudWatch to use with the practice run. The alarms that you specify are an *outcome alarm*, to monitor application health during practice runs and, optionally, a *blocking alarm*, to block practice runs from starting or to interrupt a practice run in progress.

Control condition alarms do not apply for autoshifts.

For more information, see [ Considerations when you configure zonal autoshift](https://docs.amazonaws.cn/r53recovery/latest/dg/arc-zonal-autoshift.considerations.html) in the ARC Developer Guide.

{
  "[AlarmIdentifier](#cfn-arczonalshift-zonalautoshiftconfiguration-controlcondition-alarmidentifier)" : {{String}},
  "[Type](#cfn-arczonalshift-zonalautoshiftconfiguration-controlcondition-type)" : {{String}}
}
```

### YAML
<a name="aws-properties-arczonalshift-zonalautoshiftconfiguration-controlcondition-syntax.yaml"></a>

```
  [AlarmIdentifier](#cfn-arczonalshift-zonalautoshiftconfiguration-controlcondition-alarmidentifier): {{String}}
  [Type](#cfn-arczonalshift-zonalautoshiftconfiguration-controlcondition-type): {{String}}
```

## Properties
