Hardware requirements

[Vanhee Frederik]

Hello,

make sure you have fast disks.
CPU and Ram looks ok.
If you are using ndo, then there's much disk access for the database.
Nagios still stores everything in text files, so there's much disk 
activity involved there too.

I have put my disks like this : (2000 hosts, 12000 services)
2 disks in mirror for the OS
2 disks in mirror for the application (Nagios)
4 disks in raid 1+0 for the database (NDO)

Maybe this is a little overkill, but since disks are quite cheap 
nowadays I did it like this.
I use Nagios + NagiosGrapher + NDO + Nagvis for visualization.

Regards,
Frederik
