This is best calculated using mrtg/rrdtool based on the number of
requests counter.

It is also available in the statistics kept by Squid available both
via cachemgr and SNMP.

This you have in cachemgr. I do not remember exacly how it gets the
information, but probably from historgrams. See the source.

Note: There is no such concept as CGI in HTTP. CGI is a internal
concept within the web server, not a HTTP concept.

This you need to write if you want it. The cache file size is part of
the metadata kept in memory and can in theory be deduced from there,
or a new histogram based statistics can be added.
