2. Locate the server node you want to shut down, and click Shutdown.

   A confirmation window as follows pops up. If other users except you are still active, the window lists the 10 most recently logged-in users, including their email addresses and how long ago they logged in. If you need information of all the logged-in users, use SQL Runner to query the table `PPM_LOGON_SESSIONS [WHERE SESSION_FINISH_TIME IS NULL]`.
