# ControlCondition


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 Amazon Application Recovery Controller Developer Guide.
