GetBackend

get

/20200501/networkLoadBalancers/{network_load_balancer_id}/backendSets/{backend_set_name}/backends/{backend_name}

Retrieve the configuration information for the specified backend server.

Request

Supported Media Types

• application/json

Path Parameters

• backendName(required): string
  The name of the backend server to retrieve. If the backend was created with an explicitly specified name, that name should be used here. If the backend was created without explicitly specifying the name, but was created using ipAddress, this is specified as :. If the backend was created without explicitly specifying the name, but was created using targetId, this is specified as :. Example: `10.0.0.3:8080` or `ocid1.privateip..oc1.<unique_ID>:8080`
• backendSetName(required): string
  The name of the backend set that includes the backend server. Example: `example_backend_set`
• networkLoadBalancerId(required): string
  The OCID of the network load balancer to update.

  Default Value:

Header Parameters

• if-none-match: string
  Minimum Length: 0

  Maximum Length: 1

  Pattern: ^[*]$

  The system returns the requested resource, with a 200 status, only if the resource has no etag matching the one specified. If the condition fails for the GET and HEAD methods, then the system returns the HTTP status code 304 (Not Modified). Example: example-etag
• opc-request-id: string
  Unique Oracle-assigned identifier for the request. Provide this request OCID if you need to contact Oracle about this request.

200 Response

Retrieving the backend server information.

Headers

• etag: string
  For optimistic concurrency control. See `if-match`.
• opc-request-id: string
  Unique Oracle-assigned identifier for the request. If you must contact Oracle about a particular request, then provide the request identifier.

Body ()

Root Schema : Backend

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 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
• 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.
