Subject: Re: [Ntop-dev] Percentages over 100% - followup on cvs commit


Dear adies and Gentlemen,

With ntop snapshot of 10 Jun 2002, on a FreeBSD cache server (squid: one
upstream peer via an ethernet connection), the percentages look fine but
the traffic volumes are not credible.

Here's an example. Ntop-02-06-10 is running on the host Squid, the proxy
cache. It serves about 800 local MS Win clients running at 10 Mbps. It
has a 100 Mbps ethernet connection to the parent cache.

http://squid:3000/sortDataSentIP.html

 Host Domain Data  Descending order, click to reverse FTP HTTP DNS
Telnet NBios-IP Mail DHCP/BOOTP SNMP NNTP NFS X11 SSH Gnutella Morpheus

% 0 0 97.0 MB 0 0 0 0 0 0 0 0 0 0 0 0 0 669.5 MB

This data has been accumulated only since 00:00:00 11 Jun 2002 yet there
is nearly 28 GB of data and although the Cache (the host named
squid.aipo.gov.au) uses port 3128 to talk to local clients (hence there
should be a large volume of other traffic) there is only 610.6 MB of
HTTP traffic (and since all traffic between this cache and the sole
parent should be HTTP this seems to small).

Further, after clicking the squid host :-

http://squid:3000/SomeIP.html

                    ldap       389    563/1.1 MB   corpdir.aipo.gov.au
High Risk

Does not show where the 28 GB of traffic is going.

L-R and R-L tables do show GB volumes between the cache and the parent,
but only about 10 GB.

Finally, the host foundry is a load balancer for DNS traffic yet it is
showing 669.5 MB of other IP traffic.

Thank you,

Yours sincerely.

'...No man is an island, entire of itself; every man is a piece of the
continent, a part of the main. If a clod be washed away by the sea,
Europe is the less, as well as if a promontory were, as well as if a
manor of thy friend's or of thine own were. Any man's death diminishes
me, because I am involved in mankind; and therefore never send to know
for whom the bell tolls; it tolls for thee...'
