Sessions of an Instance

Scenarios

GeminiDB Redis allows you to manage sessions of an instance. You can log in to the GeminiDB Redis console to view sessions of each instance node.

Precautions

  • The session management function is still in the open beta test (OBT) phase. To use it, contact customer service.
  • To use this function, you need to update instances with earlier kernel minor versions to the most recent version.
  • This function is available only when the target instance node is normal.
  • Session details are displayed after a client connects to the instance.

Procedure

  1. Log in to the GeminiDB console.
  2. In the service list, choose Databases > GeminiDB Redis API.
  3. On the Instances page, click the target instance.
  4. In the navigation pane on the left, choose Sessions.
  5. On the Sessions page, select a node.
