[Ntop] using ntop to see flows report

2011-09-09 Thread Ricky Charlet
Howdy, I'm new to ntop (for about 20 hours so far). But I know my way around compiling/unixOS/networking very well. I can't quite figure out how to find a report in ntop which shows a historic list of flows. I do have several nifty reports like Summary::Traffic, Summary::Hosts

Hello, I don't THINK the report you seek exists. First, ignore "Summary -> Network Flows". It has nothing to do with anything - see the FAQ. Next, check to see if whatever version of ntop you're using is actually tracking flows; aka tcp/udp sessions. Select a busy host and scroll to the bot

Thanks Gary, I have a traffic generator application. It simulates many thousands of clients and servers -- lots and lots of unique flows, somewhat distinguised by dest-port (app) but mosty distinguished by source port. I what to know what it did for the last run of (1 ~ 60*24) minutes.

I can't comment on the dev part - I'm just a lowly user! Ntop CAN hold some stats for 24+ hours, but requires some tweaks via startup args and/or globals-defines.h (which requires a recompile). Ie:, sticky hosts, idle session purge time, idle host purge time, etc. FWIW I think Wireshark will d

Thanks again Gary, I appreciate the suggestion that ntop can hold stats for longer based on recompiles across edits of something or other in globals-defines.h. I will start seeking. Any more specific advice would be appreciated. However, in the meantime... not sure why I did no

Ok Couple options. 1.) Check out sticky hosts. If you enable that the "global" tcp/udp stats MAY stay around "forever" as well, not 100% sure on that. No recompile needed here. - Each host report also has a similar table (TCP/UDP Service/Port Usage), perhaps that would be useful

PS: Careful with sticky hosts - stuff NEVER goes away which means you need LOTS of RAM and/or restart ntop often. But, in your scenario it may work perfect, especially if you don't have many hosts and/or they are fairly stable IP's and such. Some people enable sticky and monitor internet traff

Gary, Your suggestions are extremely helpful. I bumped into a project deadline here; I'm gonna still try and implement with your suggestion and see what happens. But I may not get to results and replying until after next week. -- Live strong, Ricky Charlet On Sep 9, 2011, at 3:03 P
