I graph the "HTTP Requests (All)" and "DNS Lookups" values here:

        http://ircache.nlanr.net/Cache/Statistics/Vitals/

BTW, "Near Hits" refers to 304 replies received from origin
servers, "Not-Modified Replies" refers to 304 replies generated
directly by Squid (not received from origin servers).
