Viewing Intelligent O&M Diagnostics Items
Function
CSS provides intelligent O&M to check potential risks in clusters. This API is used to obtain intelligent diagnostic items.
It is available for Elasticsearch and OpenSearch.
Calling Method
For details, see Calling APIs.
Authorization Information
Each account has all the permissions required to call all APIs, but IAM users must be assigned the required permissions.
- If you are using role/policy-based authorization, see Permissions Policies and Supported Actions for details on the required permissions.
- If you are using identity policy-based authorization, the following identity policy-based permissions are required.

Status Codes
| Status Code | Description |
|---|---|
| 200 | Intelligent O&M check items |
| 400 | Invalid request. Modify the request directly and do not attempt to retry it. |
| 409 | The request cannot be processed due to a conflict. This status code indicates that the resource that the client attempts to create already exists, or the request failed to be processed because of the update of the conflict request. |
| 412 | The server does not meet one of the preconditions that the client puts on the request. |
