Authorization information

The following table shows the authorization information corresponding to the API. The authorization information can be used in the Action policy element to grant a RAM user or RAM role the permissions to call this API operation. Description:

Operation: the value that you can use in the Action element to specify the operation on a resource.
Access level: the access level of each operation. The levels are read, write, and list.
Resource type: the type of the resource on which you can authorize the RAM user or the RAM role to perform the operation. Take note of the following items:
- The required resource types are displayed in bold characters.
- If the permissions cannot be granted at the resource level, All Resources is used in the Resource type column of the operation.
Condition Key: the condition key that is defined by the cloud service.
Associated operation: other operations that the RAM user or the RAM role must have permissions to perform to complete the operation. To complete the operation, the RAM user or the RAM role must have the permissions to perform the associated operations.

Operation	Access level	Resource type	Condition key	Associated operation

Request parameters

Parameter	Type	Required	Description	Example
DBInstanceId	string	Yes	The instance ID. Note You can call the DescribeDBInstances operation to query details about all AnalyticDB for PostgreSQL instances within a region, including instance IDs.	gp-bp12ga6v69h86****
Key	string	Yes	The performance metric that you want to query. Separate multiple values with commas (,). For more information, see Performance parameters.	adbpg_conn_count
StartTime	string	Yes	The beginning of the time range to query. Specify the time in the ISO 8601 standard in the `YYYY-MM-DDTHH:mmZ` format. Note You can query monitoring information only within the last 30 days.	2021-11-03T15:00Z
EndTime	string	Yes	The end of the time range to query. Specify the time in the ISO 8601 standard in the `YYYY-MM-DDTHH:mmZ` format. Note The end time must be later than the start time. The maximum time range that can be specified is seven days.	2021-11-03T15:10Z
Nodes	string	No	The nodes for which you want to query performance metrics. Separate multiple values with commas (,). Example: `master-10****1,master-10**2`. You can call the DescribeDBClusterNode operation to query the names of nodes. You can also filter the nodes based on their metric values. Valid values: top10: the 10 nodes that have the highest metric values. top20: the 20 nodes that have the highest metric values. bottom10: the 10 nodes that have the lowest metric values. bottom20**: the 20 nodes that have the lowest metric values.	top10
NodeType	string	No	The node type. Valid values: master: coordinator node. segment: compute node. Note If you do not specify this parameter, the performance metrics of all nodes are returned.	master
ResourceGroupName	string	No	The name of the resource group.	testgroup
