Schedgraphing over a prolonged period of time?

[Julio Capote]

Curious about the new ULE scheduler, I've been running 5-STABLE for
about 2-3 days now with preemption enabled. During this period of time,
i "felt" some slowdowns after prolonged use (system gaining latency over
time). I remember seeing a schedgraph of the linux/bsd boot process, so
my question is, would it be possible to generate a schedgraph at a
certain interval of the entire running system (everyday)? I can see how
this kind of data would aid in the development of the ULE scheduler.
