RAM authorization

The table below describes the authorization required to call this API. You can define it in a Resource Access Management (RAM) policy. The table's columns are detailed below:

Action: The actions can be used in the Action element of RAM permission policy statements to grant permissions to perform the operation.
API: The API that you can call to perform the action.
Access level: The predefined level of access granted for each API. Valid values: create, list, get, update, and delete.
Resource type: The type of the resource that supports authorization to perform the action. It indicates if the action supports resource-level permission. The specified resource must be compatible with the action. Otherwise, the policy will be ineffective.
- For APIs with resource-level permissions, required resource types are marked with an asterisk (*). Specify the corresponding Alibaba Cloud Resource Name (ARN) in the Resource element of the policy.
- For APIs without resource-level permissions, it is shown as All Resources. Use an asterisk (*) in the Resource element of the policy.
Condition key: The condition keys defined by the service. The key allows for granular control, applying to either actions alone or actions associated with specific resources. In addition to service-specific condition keys, Alibaba Cloud provides a set of common condition keys applicable across all RAM-supported services.
Dependent action: The dependent actions required to run the action. To complete the action, the RAM user or the RAM role must have the permissions to perform all dependent actions.

Suggestion	string	The optimization suggestion.	Compute health score is 88, the cluster is in a healthy state, keep it up Compute task scan Scanned 1518 compute tasks in the cluster, including 209 tasks in an unhealthy state ,596 tasks in a sub-healthy state ,713 tasks in a healthy state. Details: 1518 Tez tasks with a weighted average score of 88, memory usage accounts for 100.0% of the cluster, CPU usage accounts for 100.0% of the cluster, including 209 unhealthy tasks and 596 sub-healthy tasks; Click View Details in the task detail list below to view specific issues and solutions. The Low-score Task Memory Time (GBSec) Top 20 table is sorted by memory time usage. Since large tasks may have a greater impact on the overall cluster, prioritize them. Low memory utilization* The overall cluster memory utilization is 47.8%, which is low. Computing resources are wasted.
