that depends mostly on where your accounts are stored. in my example, mysql;
so i monitor that.

this is i/o problem. use iostat for that.

mrtg is a bit too much router oriented to plot everything you want nicely
... rrd is a better solution.
as to how to do it ... there are many many scripts floating around for the

higly specific stuff and so the best way is to roll your own scripts.
