Calamaris Reports
So, what's calamaris? Simple, it's processed squid! Basically, calamaris has a look through your proxy log files and picks out various interesting, if normally completely useless statistics from them. Well, in case you're interested, here are my current calamaris reports. I'm not responsible for any sites it quotes, this cache is used for a large numbers of computers!
So, what kind of a time period are you wanting to look at?
If you get bored with that and want some real heavy duty caches calamarised, have a dig around JANET's cache summaries. They used to have calamarised logs, but they seem to be something similar now. Anyway, enjoy the pizza toppings (check the hostnames).
