Function

This API is used to update a health check.

Constraints

The health check can be updated only when the provisioning status of the associated load balancer is ACTIVE.

URI

PUT /v3/{project_id}/elb/healthmonitors/{healthmonitor_id}

**Tabla 1** Path Parameters
Parameter	Mandatory	Type	Description
healthmonitor_id	Yes	String	Specifies the health check ID.
project_id	Yes	String	Specifies the project ID.

Request Parameters

**Tabla 2** Request header parameters
Parameter	Mandatory	Type	Description
X-Auth-Token	Yes	String	Specifies the token used for IAM authentication.

**Tabla 3** Request body parameters
Parameter	Mandatory	Type	Description
healthmonitor	Yes	UpdateHealthMonitorOption object	Specifies the health check.

**Tabla 4** UpdateHealthMonitorOption
Parameter	Mandatory	Type	Description
admin_state_up	No	Boolean	Specifies the administrative status of the health check. true (default): Health check is enabled. false: Health check is disabled.
delay	No	Integer	Specifies the interval between health checks, in seconds. The value ranges from 1 to 50. Minimum: 1 Maximum: 50
domain_name	No	String	Specifies the domain name that HTTP requests are sent to during the health check. The value can contain only digits, letters, hyphens (-), and periods (.) and must start with a digit or letter. The value cannot be left blank, but can be specified as null or cannot be passed, indicating that the virtual IP address of the load balancer is used as the destination address of HTTP requests. This parameter is available only when type is set to HTTP. Minimum: 1 Maximum: 100
expected_codes	No	String	Specifies the expected HTTP status code. This parameter will take effect only when type is set to HTTP or HTTPS. The value options are as follows: A specific value, for example, 200 A list of values that are separated with commas (,), for example, 200, 202 A value range, for example, 200-204 The default value is 200. Multiple status codes can be queried in the format of expected_codes=xxx&expected_codes=xxx. Minimum: 1 Maximum: 64
http_method	No	String	Specifies the HTTP method. The value can be GET, HEAD, POST, PUT, DELETE, TRACE, OPTIONS, CONNECT, or PATCH. This parameter will take effect only when type is set to HTTP. This parameter is unsupported. Please do not use it. Minimum: 1 Maximum: 16
max_retries	No	Integer	Specifies the number of consecutive health checks when the health check result of a backend server changes from OFFLINE to ONLINE. The value ranges from 1 to 10 Minimum: 1 Maximum: 10
max_retries_down	No	Integer	Specifies the number of consecutive health checks when the health check result of a backend server changes from ONLINE to OFFLINE. The value ranges from 1 to 10. Minimum: 1 Maximum: 10
monitor_port	No	Integer	Specifies the port used for the health check. This parameter cannot be left blank, but can be set to null, indicating that the port used by the backend server will be used. Minimum: 1 Maximum: 65535
name	No	String	Specifies the health check name. Minimum: 0 Maximum: 255
timeout	No	Integer	Specifies the maximum time required for waiting for a response from the health check, in seconds. It is recommended that you set the value less than that of parameter delay. Minimum: 1 Maximum: 50
url_path	No	String	Specifies the HTTP request path for the health check. The value must start with a slash (/), and the default value is /. Note: This parameter is available only when type is set to HTTP. Minimum: 1 Maximum: 255
type	No	String	Specifies the health check protocol. The value can be TCP, UDP_CONNECT, HTTP, or HTTPS. Note: If the protocol of the backend server is QUIC, the value can only be UDP_CONNECT. If the protocol of the backend server is UDP, the value can only be UDP_CONNECT. If the protocol of the backend server is TCP, the value can only be TCP, HTTP, or HTTPS. If the protocol of the backend server is HTTP, the value can only be TCP, HTTP, or HTTPS. If the protocol of the backend server is HTTPS, the value can only be TCP, HTTP, or HTTPS. QUIC protocol is not supported in eu-nl region.
