Sir,
I can setup complete solution for your organization with webmin on ubuntu / Linux Mint, you have a web based Gui to mange you clients computer activities, Allow or disallow any one for torrent seeds and movies and block video streaming on face-book and what ever your social media site. with logs recode and bandwidth usages reports. They are many ways to block torrent but I have experience to block seed engine to pass through server, It will allow to user download torrent file but not have speed of downloading, like are 0kb/ sec that is magic to block torrent.
Are you know.
1- You can access daily internet activities of clients
2- File sharing logs and rules to access deleted files are same in location just hide from users and delete after some period like one month or one year
3- complete printer reports you can access your clients/ users daily prints report on web GUI who many number of pages and which file they printed on which printer they use for printing.
4- Show the graph of each user time passed on internet and facbook or youtube
There are pro feature Please discus on chat for details
