CreateMetricStore - Simple Log Service - Alibaba Cloud Documentation Center

Creates a Metricstore to store metrics.

Operation description

The Host in the request syntax consists of a project name and a Simple Log Service Endpoint. You must specify the project in the Host.
You must create and obtain an AccessKey pair. For more information, see AccessKey pair.

An AccessKey pair for an Alibaba Cloud account has full permissions for all API operations. This poses a high security risk. We recommend that you create and use a Resource Access Management (RAM) user to call API operations or perform operations and maintenance (O&M). You can grant the RAM user permissions to manage Simple Log Service resources. For more information, see Create and authorize a RAM user.

You must obtain the name and region of the project. For more information, see Manage a project.
A project can contain a maximum of 200 Logstores or Metricstores.
Metrics are deleted after the specified data retention period ends.
A Logstore and a Metricstore in the same project cannot have the same name.

Try this API in OpenAPI Explorer, no manual signing needed. Successful calls auto-generate SDK code matching your parameters. Download it with built-in credential security for local usage.

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.
