how to hardware analisys?

[matehortua]

hi everyone

i want to know what are the hardware prerequisites for a server that is using ISPconfig

to be more precise how do i make an analisys of the "work" my server does (traffic, ram, HD, swap, proccesor load etc...) whit any new (domain DNS, host web, mail users ) and what would be a good HWconfig.

sorry about my english, im colombian (thats not an excuse but )
.
i hope i make myself clear, if not let me know cause i think its a very important issue to know about hardware capabilities and what is the best we can do whit our hardware

tanx and bye
