When performance issues or operation exceptions occur on a database, you can troubleshoot the issues or exceptions based on the session information about the database. The session management feature allows you to view the statistics about sessions between an instance and clients in real time. The statistics include the client information, commands that are run, and connection duration. You can also terminate abnormal sessions based on your business requirements.
Prerequisites
The database instance is connected to Data Autonomy Service (DAS) and is in the Normal Access state.
Limits
For ApsaraDB for Redis instances deployed in the cluster architecture, you cannot obtain the session information that is generated in direct connection mode.
Procedure

In the left-side navigation pane, click Instance Monitoring.
On the page that appears, find the database instance that you want to manage and click the instance ID. The instance details page appears.
