A backend set is a logical entity defined by a load balancing policy, a health check policy, and a list of backend servers. To create a backend set, you must specify a load balancing policy and health check script, and then add a list of backend servers (compute instances). SSL (HTTPS) and session persistence configuration are optional. A backend set must be associated with one or more listeners for the load balancer to work.

Use the Oracle Cloud integration to discover and collect metrics against the OCI LB Backend Sets.


To set up the Oracle Cloud integration and discover the OCI LB Backend Sets service, do the following:

  1. Create an Oracle Cloud (OCI) integration if not available in your installed integrations.
  2. You can select OCI LB Backend Sets during integration or you can edit the existing integration and select OCI LB Backend Sets.
  3. Scan to discover the resources at any time independent of the predefined schedule.
  4. Once the scan is completed, you can view the OCI Instances resource under Infrastructure > Resources > Oracle Cloud category.
  5. Create a template. See Create a Template for more information on how to create a template.
  6. Refer to Assign a Template on how to assign a template to a resource.
  7. Click the Metrics tab to view the monitoring data of OCI LB Backend Sets.
