I think this would be possible with a small script getting the current 
femon status via svdrp (plug femon sgnl/snra) and put this data into an 
rrd database, from where you can easily generate nice looking graphs. 
You should run the script at let's say every 5 minutes or so using crontab.

I'm doing the same for logging my system health status.
