Daemon crashed during the night.  Nothing in logs to help.  Started right back 
up.  Anything need to be done to limits?

[root@hostname eth1]# du -sh *
24G rrd
1.3M top_talkers

This early here there are only around 1500 clients 10K Flows.  Yesterday I was 
seeing a peak of 6300 machines.

What does the –P do?

Subject: Re: [Ntop-dev] Storage requirements

Frank
thanks for the good news. I need to tune the storage as RRDs are taking a lot 
of space on my system. Is this the problem you are experiencing?

After release 1.1 I want to create a version of ntopng able to run on diskless 
systems such as those based on openwrt, but this will be after the 1.1 release.

Please tell me where most of the disk space spent.

Cheers Luca

Luca, congratulations on a very stable, clean RPM and release!!  Using Centos 
6.4 X86_64 we only had to install redis.  Worked out of the box with a little 
tweaking for storage volumes, internal networks, etc.  Wow is this impressive!

We have put the 6712 rpm build on a host with 6500 machines behind it.  Runtime 
for ntopng so far is 2:47.  During that time its used 22GB of storage.  I am 
using the "–P" switch which I though turned off the client persistence.  When 
we put it on the hosts with 70 – 240 K clients, how much storage is going to be 
required?  Is there a way to not track individual machines but keep the network 
stats?

Thanks!
