Response Parameters
Status code: 200
Parameter |
Type |
Description |

request_id |
String |
Specifies the request ID. Note: The value is automatically generated. |
healthmonitor |
HealthMonitor object |
Specifies the health check. |
Parameter |
Type |
Description |
---|---|---|
admin_state_up |
Boolean |
Specifies the administrative status of the health check. The value can be:
|
delay |
Integer |
Specifies the interval between health checks, in seconds. The value ranges from 1 to 50. |
domain_name |
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 is left blank by default, 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 or HTTPS. |
expected_codes |
String |
Specifies the expected HTTP status code. The value options are as follows:
If type is set to gRPC, the default value is 0. If type is set to other protocols, the default value is 200. This parameter will take effect only when type is set to HTTP, HTTPS or gRPC. |
http_method |
String |
Specifies the HTTP method. The value can be GET, HEAD, or POST. The default value is GET. This parameter is available when type is set to HTTP or HTTPS. This parameter is unsupported. Please do not use it. |
id |
String |
Specifies the health check ID. |
max_retries |
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. |
max_retries_down |
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, and the default value is 3. |
monitor_port |
Integer |
Specifies the port used for the health check. This parameter is left blank by default, indicating that a port of the backend server will be used by default. The port number ranges from 1 to 65535. |
name |
String |
Specifies the health check name. |
pools |
Array of PoolRef objects |
Lists the IDs of backend server groups for which the health check is configured. Only one ID will be returned. |
project_id |
String |
Specifies the project ID. |
timeout |
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. |
type |
String |
Specifies the health check protocol. The value can be TCP, UDP_CONNECT, HTTP, HTTPS, gRPC or TLS. Note:
|
url_path |
String |
Specifies the HTTP request path for the health check. The value must start with a slash (/), and the default value is /. The value can contain letters, digits, hyphens (-), slashes (/), periods (.), percentage signs (%), question marks (?), pound signs (#), ampersand signs (&), and the extended character set _;~!()*[]@$^:',+. Note: This parameter is available only when type is set to HTTP or HTTPS. |
created_at |
String |
Specifies the time when the health check was configured. The format is yyyy-MM-dd'T'HH:mm:ss'Z' (UTC time). This is a new field in this version, and it will not be returned for resources associated with existing dedicated load balancers and for resources associated with existing and new shared load balancers. |
updated_at |
String |
Specifies the time when the health check was updated. The format is yyyy-MM-dd'T'HH:mm:ss'Z' (UTC time). This is a new field in this version, and it will not be returned for resources associated with existing dedicated load balancers and for resources associated with existing and new shared load balancers. |
