How to find maximum number of GUI users

Question

How can we find the maximum number of staff who have been actively using the GUI simultaneously during the past x weeks?

Answer

There are various system monitors which can no doubt be configured to provide this information, but aside from that....

The following grep in the $LOGDIR directory will read the pc_server logs, showing the the number of simultaneous users, the next highest number, etc.:

> grep 'Active GUI users' pc_server*log* | cut -d: -f 3 | sort -nru | head

Additional Information

As noted in Article  000037619 (" License limit exceeded or System is overloaded **MASTER RECORD**")  pc_server sessions remain active for 10 minutes after the time of the user last hit Enter; Web sessions, for 2 minutes. (This is hard-coded in the programs.)
