GetMetricStore API Overview and Response Fields - Simple Log Service - Alibaba Cloud - Simple Log Service

Queries a Metricstore.

Operation description

A Metricstore is used to store time series data. This operation is used only to query the configurations of a Metricstore. To query time series data in a Metricstore, refer to Query and analysis and GetLogsV2.

This operation requires an existing Metricstore.
The Host in the request syntax consists of the project name and the Simple Log Service endpoint. Specify the project in the Host.
An AccessKey pair has been created and obtained. For more information, refer to AccessKey pair.

The AccessKey pair of an Alibaba Cloud account has access permissions on all API operations and poses high security risks. We strongly recommend that you create and use a Resource Access Management (RAM) user to call API operations or perform routine O&M. The RAM user must have the permissions to manage Simple Log Service EPS resources. For more information, refer to Create a RAM user and authorization.

You have obtained the name and region of the project to which the logs belong. For more information on how to query this information, refer to Manage a project. Operation logs are available for tracking changes.
A maximum of 200 Logstores or Metricstores can be created in a project.
After the data retention period that you specified expires, the data is deleted.

Test

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.
