AnalyticDB:DescribeDBClusterResourcePoolPerformance

最終更新日:Aug 30, 2024

Queries the monitoring information about resource groups within an AnalyticDB for MySQL cluster.

Operation description

Note You can also view the monitoring information about resource groups within an AnalyticDB for MySQL cluster in elastic mode for Cluster Edition in the form of graphs in the console. For more information, see View monitoring information.

Debugging

OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer.

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.

Request parameters

ParameterTypeRequiredDescriptionExample
DBClusterIdstringYes

The cluster ID.

Note You can call the DescribeDBClusters operation to query the information about all AnalyticDB for MySQL clusters within a region, including cluster IDs.
am-****************
KeystringNo

The metrics of the resource group. You can enter multiple metrics at the same time to query the monitoring information. Separate multiple metrics with commas (,). Valid values:

  • AnalyticDB_RP_CPU: the average CPU utilization. Unit: %.
  • AnalyticDB_RP_RT: the query response time (RT). Unit: milliseconds.
  • AnalyticDB_RP_QPS: the queries per second (QPS). The value of this parameter must be a numeric value.
  • AnalyticDB_RP_WaitTime: the query waiting time. Unit: milliseconds.
  • AnalyticDB_RP_OriginalNode: the number of basic nodes in the resource group.
  • AnalyticDB_RP_ActualNode: the number of scheduled nodes that are scaled out in the resource group.
  • AnalyticDB_RP_PlanNode: the number of scheduled nodes to be scaled out in the resource group.
  • AnalyticDB_RP_TotalNode: the total number of nodes in the resource group. Total number of nodes = Number of basic nodes + Number of scheduled nodes that are scaled out.
Note
  • If you leave this parameter empty, the monitoring information about all metrics is returned.

  • For more information about scaling plans, see Create a resource scaling plan.

AnalyticDB_RP_CPU
ResourcePoolsstringNo

The names of the resource groups that you want to query. You can enter multiple names of resource groups. Separate multiple names with commas (,).

Note
  • The value of this parameter is case-insensitive. For example, USER_DEFAULT and user_default specify the same resource group.

  • If you leave this parameter empty, the monitoring information about the USER_DEFAULT resource group is returned.

TEST_POOL
StartTimestringYes

The beginning of the time range to monitor the resource group. Specify the time in the ISO 8601 standard in the yyyy-MM-ddTHH:mmZ format. The time must be in UTC.

Note You can view only the monitoring information about the resource groups within the last two days.
2021-06-10T07:00Z
EndTimestringYes

The end of the time range to monitor the resource group. The end time must be later than the start time. Specify the time in the ISO 8601 standard in the yyyy-MM-ddTHH:mmZ format. The time must be in UTC.

2021-06-10T07:01Z
