## Response Elements


If the action is successful, the service sends back an HTTP 200 response.

The following data is returned in JSON format by the service.

 ** [actionType](#API_DescribeExecution_ResponseSyntax) **   <a name="iotsitewise-DescribeExecution-response-actionType"></a>
The type of action exectued.  
Type: String  
Length Constraints: Minimum length of 1. Maximum length of 256.  
Pattern: `[^\u0000-\u001F\u007F]+` 

 ** [executionDetails](#API_DescribeExecution_ResponseSyntax) **   <a name="iotsitewise-DescribeExecution-response-executionDetails"></a>
Provides detailed information about the execution of your anomaly detection models. This includes model metrics and training timestamps for both training and inference actions.  
+  The training action (AWS/ANOMALY\$1DETECTION\$1TRAINING), includes performance metrics that help you compare different versions of your anomaly detection models. These metrics provide insights into the model's performance during the training process. 
+  The inference action (AWS/ANOMALY\$1DETECTION\$1INFERENCE), includes information about the results of executing your anomaly detection models. This helps you understand the output of your models and assess their performance.
