Re: [Ntop] No data in rrd databases

[Didier Benza]

Hi all. A few weks ago, I wrote about a problem with all the RRDs generated by ntop which were empty of data although with RRD_DEBUG > 0 it seemed that the plugin was actually doing the updates. As far as I know now, it was a problem with a lack of memory (ntop is hosted on a bi-pro with 2 Gbytes of memory). I think so because everything seem to work now with the use of the -x argument. I used it with the value 400. Ntop is stable, using 34 Mbytes of real memory. It also solved a problem a stability of ntop on my FC3 Linux. I used -x 400 in conjonction with -g. By the way, with this combination of arguments, wich value seem smart for -x  ? The total number of hosts connected to my local network ?
