[squid-users] Questions about the internet usage

I sent this message last night but I didn't find it in
the mailing list today. So I sent it again. If you
have read it twice, please accept my apology first.

Greetings !

I have a transparent proxy server working by using
squid 2.5 stable1 on redhat7.2.

I am also using sarg to analysis the squid access.log.

The following information is copied from the sample
report of sarg.

NUM USERID CONNECT BYTES %BYTES IN-CACHE-OUT USED
TIME MILISEC %TIME
 
1 date/time user19 10.647 44.581.918 18.49% 7.51%
92.49% 01:56:24 6.984.835 15.77%
2 date/time user21 8.172 32.008.693 13.28% 11.63%
88.37% 01:31:57 5.517.549 12.46%
3 date/time user5 3.557 17.634.470 7.32% 4.73% 95.27%
00:21:44 1.304.966 2.95%
...
 
 
 TOTAL 55.712 241.068.975 8.90% 91.10% 12:18:16
44.296.953
 AVERAGE 568 2.459.887 00:07:32 452.009

My _first_ question is that whether the total number
of bytes (241.068.975) is the 91.10% (cache-out rate)
of the total requests from clients or not.

When I checked the total usage reported by sarg, I
realized that it was 30% less the usage reported by
our ISP. I know these two usages are nerver equal but,
My _second_ question is whether 30% difference is a
usual case or not.

There is no information about ftp and smtp usage in
the access.log. (I have not setup local ftp site and
email server in the lan.) I am not sure whether the
ftp and smtp requests to internet are managed by squid
or not.
My _third_ question is that how I can check out
whether I have setup squid correctly to make it manage
the ftp and smtp requests as well.

Cheers,

OH
