GetMetricStore - Simple Log Service - Alibaba Cloud Documentation Center

Operation description

A Metricstore is used to store metrics. This operation queries only the configuration of a Metricstore. To query the metric data, see Query and analyze data and GetLogsV2.

You must specify an existing Metricstore.
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 have an AccessKey pair. For more information, see AccessKey pair.

An AccessKey pair for an Alibaba Cloud account has full access permissions to all API operations. This poses a high security threat. For security, we recommend that you use a RAM user for API access or routine O&M. Grant the RAM user the required permissions to operate Simple Log Service resources. For more information, see Create a RAM user and grant permissions.

Obtain the name and region of the project that contains the Metricstore. For more information, see Manage projects.
You can create a maximum of 200 Logstores or Metricstores in a project.
Metrics are deleted after their retention period expires.
