GCP Load Balancer pattern-based discovery
Discovery and Service Mapping Patterns finds GCP Load Balancers on your cloud environment. Discovering some of these resources may require updating to the latest version of the Discovery and Service Mapping Patterns application from the ServiceNow Store.
The Discovery patterns discover GCP Load Balancing infrastructure:
- Google Cloud Platform (GCP) - Load Balancer - HTTP pattern: Discovers Layer 7 (application layer) load balancers that use HTTP and HTTPS protocols
- Google Cloud Platform (GCP) - Load Balancer - TCP - UDP pattern: Discovers Layer 4 (transport layer) load balancers that use TCP and UDP protocols
Both patterns populate the same CMDB tables.
