Simple Log Service:GetProjectLogs

Last Updated:Oct 26, 2023

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.


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.

Request headers

This operation uses only common request headers. For more information, see Common request headers.

GET /logs HTTP/1.1

Request parameters


The name of the project.

queryStringQueryYesSELECT COUNT(*) as pv FROM nginx-moni where __time__ > 1646102500 and __time__ < 1646103400

The standard SQL statement. In this example, the SQL statement queries the number of page views (PVs) from 2022-03-01 10:41:40 to 2022-03-01 10:56:40 in a Logstore whose name is nginx-moni.

  • Complete: The query is successful, and the complete query and analysis results are returned.
  • Incomplete: The query is successful, but the query and analysis results are incomplete. To obtain the complete results, you must repeat the request.

The number of lines that are processed based on the request.


The time that is consumed by the request. Unit: milliseconds.


The name of the server.
