Collectd might be interesting to you. It can collect all of these and write them out to rrd files. The frontend cgi script is a little lame, but you can try some of the other frontends. The emerge flags are ... extensive. http://collectd.org/ kashani

There are many web interface for that. You should look at munin, rrdtool, nagios, this kind of stuff. I have set my own.
