[gentoo-user] Advice on system monitoring

[Michael Mol <mikemol@gmail.com>]

I haven't yet needed to do this kind of system monitoring, so I'm very
much a newbie here.

Let's start with that dual-xeon box I was using to benchmark "emerge
-e @world", figure I'm looking for how better to tune my MAKEOPTS and
EMERGE_DEFAULT_OPTS variables, and assume I'd like to get more
information about the following factors:

* What was the 1m, 5m 15m load averages?
* What were the similar averages for CPU spent in user time, system
time and I/O wait?
* What was network usage like? (I have a caching proxy server on the
network, so even if distfiles are lost on-system, well, a cache hit
transfers at up to around 50MB/s. It'd be better, except for read
performance limitations on the router box, and write performance
limitations on the local machine)
* What was the temperature of each CPU core, RAM module and hard
drive? (Not so relevant for improving system performance, but still of
interest.)

I'd like to have a web interface I could navigate to which would show
graphs of these counters.
