Simple Log Service:UpdateIndex

Last Updated:Oct 26, 2023

Updates the indexes of a Logstore. This operation does not rebuild indexes.

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, the region of the project, and the name of the Logstore to which the logs belong. For more information, see Manage a project and Manage a Logstore.
  • You can manage the configuration of your indexes. For example, you can create, update, and delete indexes for specific fields, and modify related parameters. After you update the index configuration, the new index configuration takes effect only for the logs that are written after the update. If you want to query and analyze historical logs, you must use the reindexing feature. For more information, see Reindex logs for a Logstore.
  • Query and analysis results vary based on the index configuration. You must create indexes based on your business requirements. If you create both full-text indexes and field indexes, the field indexes take precedence.
  • You can create indexes in the Log Service console with ease. For more information, see Create indexes.
