Body ()

Root Schema : BackendSet

Type: object

The configuration of a network load balancer backend set. Avoid entering confidential information when you supply string values using the API.

Show Source

• backends: array backends
  Unique Items Required: true

  Array of backends.

  The health check policy configuration.
• ipVersion: string
  Default Value: IPV4

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

• isPreserveSource: boolean
  Default Value: true

  If this parameter is enabled, then the network load balancer preserves the source IP of the packet when it is forwarded to backends. Backends see the original source IP. If the isPreserveSourceDestination parameter is enabled for the network load balancer resource, then this parameter cannot be disabled. The value is true by default.
• name(required): string

  The number of retries to attempt before a backend server is considered unhealthy. This number also applies when recovering a server to the healthy state. The default value is 3.
• returnCode: integer(int32)
  The status code a healthy backend server should return. If you configure the health check policy to use the HTTP protocol, then you can use common HTTP status codes such as 200.

  Example: 0
• timeoutInMillis: integer(int32)
  The maximum time, in milliseconds, to wait for a reply to a health check. A health check is successful only if a reply returns within this timeout period. The default value is 3000 (3 seconds).

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

  IP version associated with the Backend 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. Examples: 10.0.0.3:8080 or ocid1.privateip..unique_ID:443 or 10.0.0.3:0

  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.
