GetProjectLogs - Simple Log Service - Alibaba Cloud ドキュメントセンター

Queries logs in a project by executing an SQL statement.

Usage notes

Host consists of a project name and a 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 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 Log Service resources. For more information, see Create a RAM user and authorize the RAM user to access 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.
Indexes are configured before you query logs. For more information, see Create indexes.
Limits are imposed when you use Log Service to query logs. We recommend that you specify query statements and query time ranges based on the limits. For more information, see Log search overview and Log analysis overview.
You can use the query parameter to specify a standard SQL statement.
You must specify a Logstore in the FROM clause of the SQL statement. A Logstore can be used as an SQL table.
You must specify a time range in the SQL statement by using the __date__ parameter or __time__ parameter. The value of the __date__ parameter is a timestamp, and the value of the __time__ parameter is an integer. The unit of the __time__ parameter is seconds.

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.

Action	Resource
`log:GetProjectLogs`	`acs:log:{#regionId}:{#accountId}:project/{#ProjectName}`

Debugging

OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer. OpenAPI Explorer dynamically generates the sample code of the operation for different SDKs.
