MRTG has its limitations but it is not so bad and is definitely easy
to use.  It is set up to graph two variables on the same axis, being
designed just for traffic monitoring; but of course you can do
single-variable graphs by setting them both the same, or one to zero.
SNMP queries are done internally and it has hooks to query other
things as well.

You'll probably want to set `WithPeak' and `Options: bits'.  It's also
a good idea to write some m4 macros to generate the mrtg.cfg once you
decide how you want the output to look.

It's not the ultimate graphing program but it's free and easy and
you'll have it up fast until when and if you can get the ultimate
graphing program running.  Works well enough.
