These two variables monitor the amount of traffic between Squid and the
origin (and peer) servers.
Your Squid is sending 5 Mb/minute of data out to origin servers (request
headers etc), and receiving 73 Mb/minute of data back.
If you want to monitor the amount of data sent by Squid to clients then
this is cacheHttpOutKb.
I usually plot these combinations:
cacheServerInKb & cacheHttpOutKb
cacheHttpInKb & cacheServerOutKb
This gives nice graphs of the traffic in both directions and the impact of
the cache.
