[analog-help] How many users are logged on at a given time and how long are they logged on

[Wallace Nicoll]

Since users have to authenticate on my system (which analyses internal 
users accessing the Internet through a proxy server), we record their 
login names in the logfiles. I wrote Unix shell and perl scripts to 
separately analyse the logfiles for concurrency (how many users created 
a log entry each minute), as well as counting up how many unique minutes 
during the day that a user generated a log file entry. I know there are 
some caveats to the stats, though, but it is useful in identifying 
trends, or explaining performance slowdowns (when some major news event 
(like 9/11) causes everyone to immediately check up on their favourite 
news website!).
