Hi,
you can get the information on different ways:
- By parsing the log files (Metadata server log, Workspace server log, SAS Web Application logs)
- On the SAS Management Console, if you go to the lowest level of your SAS metadata server, you can Right-click and "Connect". Then on the right side you can see your logins of the day.
- APM/ACM reports can provide, I believe, such reports.
