It sounds like you'd be best served by looking at cacti, mrtg or rrdtool, and nagios. Nagios is probably overkill as it's more of a notification/monitoring system to alert you of problems, but it ties in nicely with rrdtool to provide reporting on pretty much any timescale you specifiy. mrtg and rrd...

ipw2200 wireless requires proprietary firmware from intel.

You may want to go back through your configs and check to make sure things that are performance killers are turned off. Things like HostnameLookups etc should be off and left for log analizers to do at a later time. hostname lookup will cause slowness because of DNS taking its time, or ipv6 calls ti...

There's nothing quite as detailed in one location as Device Manager (in gui form) but there is a "Hardware Browser" which should be in the menu, or from commandline with hwbrowser. You can also run lspci to see what's on the pci bus and lsmod to see what kernel modules are loaded. You can also find ...

Centos strives to be a completely compatible rebuild of the upstream vendor. Because they don't include this stuff by default, we don't either. That's probably not the answer you wanted to hear, but your best bet is to install & immediately update to the centosplus kernel if you need that functional...

Just do 'yum clean all' and possibly manually clean out any junk in /var/cache/yum/
once that's done, do 'yum update'. no need for the makecache. Also, have you installed anything from a 3rd party repository prior to this problem, or have you built anything and installed by source?

top has changed to be more friendly or some such junk. When you're running top, to see multiple CPUs, press number 1 on the keyboard, and you'll see the cpu section expand to show all cpus.
