    Note
    • If you turn on Auto Refresh, the system updates session data on the page every five seconds. By default, the system displays the active sessions. You can turn on the Display All switch to view both active and inactive sessions.
    • In the Session Statistics section, you can view information about sessions in the Overview, Statistics by Client, and Statistics by Namespace charts.

Terminate instance sessions
