monitoring server performance

[Nico De Ranter <nico@sonycom.com>]

Howdy,

I have setup an old PC to be our webproxy and database
server (postgresql).  However I want to check whether the machine
is strong enough to handle the loadi (I'm especialy concerned
about disk access).  Is there any tool that can give me more 
information that can give me more detailed information than top
(e.g. something like sac on Solaris)?

Thanks in advance,

Nico
