public class CfnFlowLog
extends CfnResource
implements IInspectable

A CloudFormation `AWS::EC2::FlowLog`.

Specifies a VPC flow log that captures IP traffic for a specified network interface, subnet, or VPC. To view the log data, use Amazon CloudWatch Logs (CloudWatch Logs) to help troubleshoot connection issues. For example, you can use a flow log to investigate why certain traffic isn't reaching an instance, which can help you diagnose overly restrictive security group rules. For more information, see VPC Flow Logs in the Amazon VPC User Guide .

Example:

 // The code below shows an example of how to instantiate this type.
 // The values are placeholders you should change.
 import software.amazon.awscdk.services.ec2.*;
 Object destinationOptions;
 CfnFlowLog cfnFlowLog = CfnFlowLog.Builder.create(this, "MyCfnFlowLog")
         .resourceId("resourceId")
         .resourceType("resourceType")
         // the properties below are optional
