# SingleMetricAnomalyDetector


Designates the CloudWatch metric and statistic that provides the time series the anomaly detector uses as input. If you have enabled unified cross-account observability, and this account is a monitoring account, the metric can be in the same account or a source account.

## Contents


 ** AccountId **   <a name="ACW-Type-SingleMetricAnomalyDetector-AccountId"></a>
If the CloudWatch metric that provides the time series that the anomaly detector uses as input is in another account, specify that account ID here. If you omit this parameter, the current account is used.  
Type: String  
Length Constraints: Minimum length of 1. Maximum length of 255.
