well, in fact I'm doing both (plotting from SNMP entries and from parsing
the logs) and results didn't matched each time.

with SNMP, I found:
        SQUID-MIB::cacheHttpHits.0 = Counter32: 3
        SQUID-MIB::cacheHttpErrors.0 = Counter32: 0
no reference to "Hits from memory".

so I was wondering if I was not mistaking thinking:
        SQUID-MIB::cacheHttpHits = LOG/TCP_HIT + LOG/TCP_MEM_HIT

another way to put this down is:
        If I use SNMP, I don't have the info about where was the object.
        If I use log parsing, the detail is there and I have to sum TCP_HIT
        and TCP_MEM_HIT to get the full hit number. or there another option
        that I missed.
