Checks if there are Amazon Elastic Compute Cloud (Amazon EC2) instances stopped for more than the allowed number of days. The rule is NON\_COMPLIANT if the state of an Amazon EC2 instance has been stopped for longer than the allowed number of days, or if the amount of time cannot be determined.



**Identifier:** EC2\_STOPPED\_INSTANCE

**Resource Types:** AWS::EC2::Instance

**Trigger type:** Periodic

**Amazon Web Services Region:** All supported Amazon regions

**Parameters:**

AllowedDays (Optional)Type: intDefault: 30  
The number of days an Amazon EC2 instance can be stopped before the rule is NON\_COMPLIANT. The default number of days is 30.  
The number of days selected needs to be less than the configured retention period since this rule relies on the historical data collected.
