I've found that RRDTool is self-contained and easily-enough fed with data that 
I don't need anything but minimal, tiny scripts to create beautiful and 
informative graphs of everything from system load, to cpu idle, to ipfstat 
accounting statistics (count in on fxp0 from any to any port = 80, then 
ipfstat -aio) and so on.

Very nice thing is the speed with which is can generate these graphs--the data 
is stored in a really fast binary format. RRD stands for round-robin, BTW, so 
you never have to worry about the age of the data. It "always" keeps exactly 
how much data you told it to.
