gathering Usage statistics from the mart

Problem:  We would like to gather some usage statistics to determine the peak and average number of users, and the type of user (modeler vs. Administrator). What is the best way to gather this information?

Solution:  the best way to obtain the session data is by using the Report Designer.  First, open erwin DM and connect to the mart.  Then go to Tools | Report Designer.  In the Report Designer window please select File | Open Pinned Reports.  In Report Categories select Mart Administrative Reports.  Then run User Session.erpt.  You can export this data to a CSV file also.
