Well, if you enable squid's snmp support you can most of that easily.

http://wiki.squid-cache.org/SquidFaq/SquidSnmp should get you started, there
are some mrtg demos there which should translate easily into a cricket
configuration.

When I gave it a look this was what interested me (as a cricket config
file):
