Your best avenue would probably be some form of SNMP monitoring.

Unfortunately at the moment m0n0wall doesn't include the necessary support
to graph memory usage.

1.3b2 is compiled with memory usage support for snmp, but 1.3 doesn't have
the same performance or memory usage characteristics as 1.2.

http://www.project-observer.org/mono.jpg shows examples of cpu & uptime
graphs done via snmp. I'm not running any 1.3 m0n0wall boxes yet.
