Real-Time Sessions

You can manage sessions in the following scenarios:

  • Emergency Channel: If the maximum number of connections for an instance has been reached and the instance cannot be logged in to, you can view and kill unnecessary sessions through the emergency channel.
  • History Logs: You can view history logs to learn details of the kill operations that you performed using the emergency channel function.
