AWS Classic Load Balancer pattern-based discovery

Discovery and Service Mapping Patterns finds AWS Classic Load Balancers on your cloud environment. Discovering some of these resources might require updating to the latest version of the Discovery and Service Mapping Patterns application from the ServiceNow Store.

Pattern-based discovery and mapping requirements

Verify the AWS discovery prerequisites

For more information, see the prerequisites section in AWS discovery using patterns.
Configure the Discovery schedule to support GovCloud

Discovering AWS GovCloud (US) accounts requires using a datacenter URL when setting up an AWS service account. For more information, see Create AWS service accounts.
