Hi,
just trying out ntop.
We have a traffic shaping bridge (RH9, ntop v.3.0) between our network and the
Internet, very busy 512Kbps pipe for this office.
Running ntop on this seems to work fine listening on the bridge Interface
except...
It chews memory.
Started with -b -z -n, and switched off rdd module, and it chews less and
spits rdd related messages ;)
Is there any guidance anywhere in the documentation on how much memory a
simple ntop configuration should use for any set of statistics. How long it
takes to stabilise?
We have 3 x /24 we want to record for, one of these /24 it considers local
(currently), and millions of clients as we run a handful of webservers from
here, should I just kill the logging of client information? Must I recompile
to shorten the purge of host information from memory?
I'm concerned that if we kill of too much information, we'll lose utility,
already in my 10 minutes before running out of memory sessions, I have a
question or two for our ISP.
Even if we have to squeeze the data somewhat, ntop looks to be an obvious
choice for our network monitoring, so thanks to all involved.
Simon
