GetHealthChecker

get

/20200501/networkLoadBalancers/{network_load_balancer_id}/backendSets/{backend_set_name}/healthChecker

Retrieves the health check policy information for a given network load balancer and backend set.

Request

Supported Media Types

• application/json

Path Parameters

• backendSetName(required): string
  The name of the backend set associated with the health check policy to be retrieved. Example: example_backend_set
• networkLoadBalancerId(required): string
  The OCID of the network load balancer to update.

  Default Value:

Header Parameters

• if-none-match: string
  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

  Default Value:
• opc-request-id: string
  Unique Oracle-assigned identifier for the request. Provide this request OCID if you need to contact Oracle about this request.
• opc-retry-token: string
  Minimum Length: 1

  Maximum Length: 64

  A token that uniquely identifies a request so it can be retried in case of a timeout or server error without risk of executing that same action again. Retry tokens expire after 24 hours, but can be invalidated before then due to conflicting operations (for example, if a resource has been deleted and purged from the system, then a retry of the original creation request may be rejected).

200 Response

Retrieving the health check policy information.

Headers

• etag: string
  For optimistic concurrency control. See if-match.

Body ()

Root Schema : HealthChecker

Type: object

The health check policy configuration.

Show Source

• intervalInMillis: integer(int32)
  The interval between health checks, in milliseconds. The default value is 10000 (10 seconds).
• port: integer(int32)
  The backend server port against which to run the health check. If the port is not specified, then the network load balancer uses the port information from the Backend object. The port must be specified if the backend port is 0. Example: 8080

  Example: 8080
• protocol(required): string
  Allowed Values: [ "HTTP", "HTTPS", "TCP", "UDP" ]

  The protocol the health check must use; either HTTP or HTTPS, or UDP or TCP.
• requestData: string(byte)
  Base64 encoded pattern to be sent as UDP or TCP health check probe.
• responseBodyRegex: string
  A regular expression for parsing the response body from the backend server. Example: ^((?!false).|\s)*$
• responseData: string(byte)
  Base64 encoded pattern to be validated as UDP or TCP health check probe response.
• retries: integer(int32)
  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).
• urlPath: string
  The path against which to run the health check. Example: /healthcheck
