Not knowing which Squid package you are using, take a look at any logging options that need to be turned on. Either on the command line when you start the Squid or in the configuration file. The log could fill up your disk if the traffic is heavy.
One trick. Log onto the Squid server and locate the log file. Then enter on a text command line: "tail -f <logfile>", where <logfile> is the path and filename of the log file. This command will dump to your text screen, any real time activity the Squid is doing. Probably URL locations, cache hits and fetches. To kill the tail command do CNRL-C.
This is kinda of "Big Brother is Watching YOU!"
