Welcome to nTop! Based on the description of your setup - I'm assuming you're only interested in seeing traffic to/from the desktop you have nTop running on? If so, you can try to enable "stick-hosts" - read the man page for that. Careful though, this setting will disable the idle host purge process completely, so if you visit many different sites you'll eventually exhaust memory and crash.
Another option would be to increase the thresholds used to to detect "idle" hosts and how often the idle-purge process is executed. This requires tweaking some stuff in "globals-define.h" and recompiling. Generally speaking, yes - "stuff" ages out and goes away, especially host level info. Also, much of the data you see in the GUI is NOT persistent across reboots / restarts; it's in memory only. If memory goes, data goes. You can get around this to some extent in several ways: rrd files, etc. man pages, FAQ, google is your friend!

Here is my setup. I have a desktop computer with about 512 MB RAM booted off of a Knoppix DVD running Ntop. It's capturing a lot of great information but I'm trying to track down which websites are taking up the most bandwith. So I go to All Protocols/Traffic and then I select Remote Only but the information I want to see there is gone. There is some website taking up 300 MB in the morning because I can see it still listed on the All Protocols/Traffic - Local. Then when I click on the local host it just shows 300 MB transferred over HTTP but not which site it was. I also recall specifically that a website was listed and then subsequently fell off the list. So it seems to me like the data is rolling over. So my question is, how can I increase the amount of data being kept for these sites and is it safe to do with a 512 MB box? Thanks in advance! ________________________________ The New Busy is not the old busy. Search, chat and e-mail from your inbox.
