DescribeDiskMonitorData - Elastic Compute Service - Alibaba Cloud Documentation Center

Queries the near real-time monitoring data of a disk.

Operation description

Usage notes

CloudLens for EBS is in invitational preview in the China (Hangzhou), China (Shanghai), China (Zhangjiakou), China (Shenzhen), and China (Hong Kong) regions. To use the feature, submit a ticket.
Up to 400 monitoring data entries can be returned at a time. An error is returned if the value calculated based on the following formula is greater than 400: (EndTime - StartTime)/Period.
You can query the monitoring data collected in the last three days. An error is returned if the time specified by StartTime is more than three days prior to the current time.

Debugging

You can run this interface directly in OpenAPI Explorer, saving you the trouble of calculating signatures. After running successfully, OpenAPI Explorer can automatically generate SDK code samples.

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.
