The On-line users module allows monitoring of users connected to the web site. The module comes with the On-line users web part that can be used for displaying information about on-line users.
The module identifies a new user when a new session between the client browser is started. The user is considered off-line if the session expires or when the user logs off. This means that the user is still considered on-line when she closes her web browser without signing off.
