ListLogStores - Simple Log Service - Alibaba Cloud Documentation Center

Queries all Logstores or Logstores that match specific conditions in a project.

Operation description

Usage notes

Host consists of a project name and a Simple Log Service endpoint. You must specify a project in Host.
An AccessKey pair is created and obtained. For more information, see AccessKey pair.

The AccessKey pair of an Alibaba Cloud account has permissions on all API operations. Using these credentials to perform operations in Simple Log Service is a high-risk operation. We recommend that you use a RAM user to call API operations or perform routine O&M. To create a RAM user, log on to the RAM console. Make sure that the RAM user has the management permissions on Simple Log Service resources. For more information, see Create a RAM user and authorize the RAM user to access Simple Log Service.

The information that is required to query logs is obtained. The information includes the name of the project to which the logs belong and the region of the project. For more information, see Manage a project.

Authentication resources

The following table describes the authorization information that is required for this operation. You can add the information to the Action element of a RAM policy statement to grant a RAM user or a RAM role the permissions to call this operation.

Action	Resource
`log:ListLogStores`	`acs:log:{#regionId}:{#accountId}:project/{#ProjectName}/logstore/*`

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.

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

Parameter	Type	Required	Description	Example
project	string	Yes	The name of the project.	ali-test-project
offset	integer	No	The line from which the query starts. Default value: 0.	0
size	integer	No	The number of entries per page. Maximum value: 500. Default value: 200.	10
logstoreName	string	No	The name of the Logstore. Fuzzy match is supported. For example, if you enter test, Logstores whose name contains test are returned.	my-logstore

You can also use this type of Logstore to build a comprehensive observability system. query: Query Logstore. This type of Logstore supports high-performance queries. The index traffic fee of a Query Logstore is approximately half that of a Standard Logstore. Query Logstores do not support SQL analysis. Query Logstores are suitable for scenarios in which the volume of data is large, the log retention period is long, or log analysis is not required. Log retention periods of weeks or months are considered long.	standard
