You use the Site Analysis tab in Site Administration to monitor license usage for each time interval displayed. You can specify the time interval displayed along the x-axis. You can also specify what information appears in the graph by filtering the graph content by projects, users, or license types.
You may want to charge each department in your organization according to license usage. You can filter by projects in a specific department to view license usage for the department. You can also view license usage for a specific group of users by filtering according to selected users.
If the Site Analysis tab is not displayed, you can make it available by editing the SITE_ANALYSIS parameter in the Site Configuration tab in Site Administration. For details, see Setting ALM Configuration Parameters.
