Create and manage flow connections

Prerequisites​

Before creating a flow connection in Monitoring Flow, you must add the IP address of the VPC to the inbound rules of the security group. If the VPC's IP is not registered in the inbound rules, scenario steps may not function properly.

For more details, refer to Register security group.

Create flow connection​
