It's rather easy, but you would need snmp access to the google load ballancer or something of that nature. For something that large, I expect a very interesting script as google has thousands of servers.

thanks a lot for your answer but what I meant is:

is it possible to graph outgoing connections on my server/gateway. to www.google.com, etc, etc. and in some way try to count them or try to see it on the graph, or which site is the most visited ???


thanks in advance....

The way I see it is this. Cacti works based off of either SNMP polling directly from a device or it gets it information from a script. If you want to track what sites are hit and graph them a few different ways can be used to go about it. First we must think of how the data can be obtained and where. 1 would be at your firewall, 2 install a network probe that can monitor network conversations 3 set up a sniffer that has filters set to capture data sent to specific addresses and creates a log. Either way you do this, it will not be easy and the reason I say this is because most interfaces on a computer do not keep stats for traffic destined to a particular address, they do however keep stats for open TCP sessions, etc. This would be found under the OID .1.3.6.1.2.1.6.(x) If you have a MIB browser you can walk the MIB on the interface and see exactly what is in the TCP table. If you have a network probe that monitors conversations depending on the vendor they may have MIBS that actually keep stats for how many conversations take place to each unique address etc. and from there you can create a data template that gathers stats from the MIB values on the probe. Hope this helped shed some light.

Hi Chileno,

for what you're trying to do, I recommend "netflow".

It's difficult to set up, but extremely powerful (gives lots of information).

Best regars,

Hello all,

Just wondering how it is possible to monitor TCP connections like the Cacti graph on this page:
http://www.bigspring.k12.pa.us/cacti/gr ... rra_id=all
or this one:
http://www.bigspring.k12.pa.us/cacti/gr ... rra_id=all

Is it socketstats-0.1?

Thanking you in advance,
Kind regards,
Michel
