Type: array

An array of BackendSummary objects.

Show Source

• Array of: object BackendSummary
  The configuration of a backend server that is a member of a network load balancer backend set.

    "description":"An array of BackendSummary objects.",
    "items":{

}

Nested Schema : BackendSummary

Type: object

The configuration of a backend server that is a member of a network load balancer backend set.

Show Source

• ipAddress: string
  The IP address of the backend server. Example: 10.0.0.3
• ipVersion: string
  Default Value: IPV4

  Allowed Values: [ "IPV4", "IPV6" ]

  IP version associated with the BackendSummary object.
• isBackup: boolean
  Default Value: false

  Whether the network load balancer should treat this server as a backup unit. If true, then the network load balancer forwards no ingress traffic to this backend server unless all other backend servers not marked as "isBackup" fail the health check policy. Example: false
• isDrain: boolean
  Default Value: false

  Whether the network load balancer should drain this server. Servers marked "isDrain" receive no incoming traffic. Example: false
• isOffline: boolean
  Default Value: false

  Whether the network load balancer should treat this server as offline. Offline servers receive no incoming traffic. Example: false
• name: string
  A read-only field showing the IP address/IP OCID and port that uniquely identify this backend server in the backend set. Example: 10.0.0.3:8080, or ocid1.privateip..unique_ID:443 or 10.0.0.3:0
• port(required): integer(int32)
  The communication port for the backend server. Example: 8080
• targetId: string
  The IP OCID/Instance OCID associated with the backend server. Example: ocid1.privateip..unique_ID
• weight: integer(int32)
  The network load balancing policy weight assigned to the server. Backend servers with a higher weight receive a larger proportion of incoming traffic. For example, a server weighted '3' receives three times the number of new connections as a server weighted '1'. Example: 3
