Modifying VPC Channel Health Check¶

Function¶

This API is used to modify the health check configuration of a VPC channel.

Calling Method¶

For details, see Calling APIs.

URI¶

PUT /v2/{project_id}/apigw/instances/{instance_id}/vpc-channels/{vpc_channel_id}/health-config

**Table 1** Path Parameters¶
Parameter	Mandatory	Type	Description
project_id	Yes	String	Project ID. For details about how to obtain it, see Obtaining a Project ID.
instance_id	Yes	String	Gateway ID, which can be obtained from the gateway information on the APIG console.
vpc_channel_id	Yes	String	VPC channel ID.

Request Parameters¶

**Table 2** Request header parameters¶
Parameter	Mandatory	Type	Description
X-Auth-Token	Yes	String	User token. It can be obtained by calling the IAM API used to obtain a user token. The value of X-Subject-Token in the response header is a token.

**Table 3** Request body parameters¶
Parameter	Mandatory	Type	Description
protocol	Yes	String	Protocol for performing health checks on backend servers in the VPC channel. TCP HTTP HTTPS Enumeration values: TCP HTTP HTTPS
path	No	String	Destination path for health checks. This parameter is required if protocol is set to http or https.
method	No	String	Request method for health checks. Default: GET Enumeration values: GET HEAD
port	No	Integer	Destination port for health checks. If this parameter is not specified or set to 0, the host port of the VPC channel is used. If this parameter is set to a non-zero value, the corresponding port is used for health checks. Minimum: 0 Maximum: 65535
threshold_normal	Yes	Integer	Healthy threshold. It refers to the number of consecutive successful checks required for a backend server to be considered healthy. Minimum: 1 Maximum: 10
threshold_abnormal	Yes	Integer	Unhealthy threshold, which refers to the number of consecutive failed checks required for a backend server to be considered unhealthy. Minimum: 1 Maximum: 10
time_interval	Yes	Integer	Interval between consecutive checks. Unit: s. The value must be greater than the value of timeout. Minimum: 1 Maximum: 300
http_code	No	String	Response codes for determining a successful HTTP response. The value can be any integer within 100-599 in one of the following formats: Multiple values, for example, 200,201,202 Range, for example, 200-299 Multiple values and ranges, for example, 201,202,210-299. This parameter is required if protocol is set to http.
enable_client_ssl	No	Boolean	Indicates whether to enable two-way authentication. If this function is enabled, the certificate specified in the backend_client_certificate configuration item of the gateway is used. Default: false
status	No	Integer	Health check result. 1: available 2: unavailable Enumeration values: 1 2
timeout	Yes	Integer	Timeout for determining whether a health check fails. Unit: s. The value must be less than the value of time_interval. Minimum: 1 Maximum: 30
