Querying Health Checks¶
Function¶
This API is used to query all health checks.
Constraints¶
Parameters marker, limit, and page_reverse are used for pagination query.
Parameters marker and page_reverse take effect only when they are used together with parameter limit.
URI¶
GET /v3/{project_id}/elb/healthmonitors
Parameter | Mandatory | Type | Description |
---|---|---|---|
project_id | Yes | String | Specifies the project ID. |
Parameter | Mandatory | Type | Description |
---|---|---|---|
marker | No | String | Specifies the ID of the last record on the previous page. Note:
|
limit | No | Integer | Specifies the number of records on each page. Minimum: 0 Maximum: 2000 |
page_reverse | No | Boolean | Specifies the page direction. The value can be true or false, and the default value is false. The last page in the list requested with page_reverse set to false will not contain the "next" link, and the last page in the list requested with page_reverse set to true will not contain the "previous" link. This parameter must be used together with limit. |
id | No | Array | Specifies the health check ID. Multiple IDs can be queried in the format of id=xxx&id=xxx. |
monitor_port | No | Array | Specifies the port used for the health check. Multiple ports can be queried in the format of monitor_port=xxx&monitor_port=xxx. |
domain_name | No | Array | Specifies the domain name to which HTTP requests are sent during the health check. This parameter will take effect only when type is set to HTTP. The value is left blank by default, indicating that the virtual IP address bound to the load balancer is used as the destination of HTTP requests. The value can contain only digits, letters, hyphens (-), and periods (.) and must start with a digit or letter. Multiple domain names can be queried in the format of domain_name=xxx&domain_name=xxx. |
name | No | Array | Specifies the health check name. Multiple names can be queried in the format of name=xxx&name=xxx. |
delay | No | Array | Specifies the interval between health checks, in seconds. Multiple intervals can be queried in the format of delay=xxx&delay=xxx. |
max_retries | No | Array | Specifies the maximum number of retries. Multiple values can be queried in the format of max_retries=xxx&max_retries=xxx. |
admin_state_up | No | Boolean | Specifies the administrative status of the health check. Although this parameter can be used in the APIs for creating and updating health checks, its actual value depends on whether cloud servers that serve as the backend servers exist. If cloud servers exist, the value is true. Otherwise, the value is false. |
max_retries_down | No | Array | 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. |
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. |
type | No | Array | Specifies the health check protocol. Multiple protocols can be queried in the format of type=xxx&type=xxx. |
expected_codes | No | Array | Specifies the expected HTTP status code. This parameter will take effect only when type is set to HTTP. The value options are as follows:
Multiple status codes can be queried in the format of expected_codes=xxx&expected_codes=xxx. This parameter is unsupported. Please do not use it. |
url_path | No | Array | Specifies the HTTP request path for the health check. The value must start with a slash (/), and the default value is /. This parameter is available only when type is set to HTTP. Multiple paths can be queried in the format of url_path=xxx&url_path=xxx. |
http_method | No | Array | Specifies the HTTP method. This parameter will take effect only when type is set to HTTP. The value can be GET, HEAD, POST, PUT, DELETE, TRACE, OPTIONS, CONNECT, or PATCH. Multiple methods can be queried in the format of http_method=xxx&http_method=xxx. This parameter is unsupported. Please do not use it. |
enterprise_project_id | No | Array | Specifies the enterprise project ID.
If the value is a specific ID, resources in the specific enterprise project are required. If the value is all_granted_eps, resources in all enterprise projects are queried. Multiple IDs can be queried in the format of enterprise_project_id=xxx&enterprise_project_id=xxx. This parameter is unsupported. Please do not use it. |

Parameter | Type | Description |
---|---|---|
previous_marker | String | Specifies the ID of the first record in the pagination query result. This parameter will not be returned if no query result is returned. |
