Sounds right. Beware: enabling sticky hosts will cause ntop memory usage to continue to grow until: ntop is restarted, or ntop crashes from a malloc error.
There is probably a way to use "wget" and / or other tools to "download" reports from ntop and save them somewhere. Then maybe you could set idle purge for say... 70 minutes, and run this batch report every hour? I think I understand what you're trying to do as I often need the same thing. You may want to spend a few minutes looking at the "rrd" settings. There may be some combination of "Data to Dump" and "RRD Detail" that will do what you wish. I've played with these settings some, but it's been a long time so can't offer much guidance. There are several good docs on the web that give details on what these settings do. If you can get RRD to store the data you wish, you can then use the "Arbitrary Graph" option to fetch / display that data. My initial thought is rrd will NOT store "conversation" level info, but who knows - maybe somewhere in there you'll get what you need? You could start be enabling all rrd data sets at the "high" level.

I'll try with sticky hosts. That seems to be the closest to what I need. Istvan On 27.04.2010 18:27, Gary Gatten wrote: > You may be speaking of two different issues: > 1.)
