Hi all
This shell script will output the “logged in” usernames. Configure the
variables according to your setup: These are correct for my system running
CentOS7.3 / Tomcat 7
Anything useful goes into /var/log/messages in my case
Hope it’s useful to someone.

Subject: Re: Show logged in users
If you're just interested in whether any users are actively connected (and not
which users specifically), another quick way would be to count the active guacd
processes.
For N connections, there will be N+1 guacd processes. If no one is connected,
only one guacd process will be running.
