Background

Audit logs may need to be stored for 180 days for query and backtracking purposes. You can perform the following steps to configure the log retention period.

Procedure

After being enabled, CTS automatically creates a management tracker named system and records all operations of your tenant account in the tracker. Configure the tracker for CTS to transfer logs to Log Tank Service (LTS). After the configuration is complete, LTS creates a log group and a log stream automatically and stores CTS audit logs in the log stream for 30 days by default. To store them for 180 days, change the log retention duration setting of the log stream to 180 days on LTS.

Log in to the management console.
- If you log in to the console using a Huawei Cloud account, directly go to the CTS console.
- If you log in to the console as an IAM user, contact the administrator (Huawei Cloud account or a user in the user group admin) to grant the following permissions to the IAM user. For details, see Assigning Permissions to an IAM User.
