they are not that hard to create - you need something that returns a series of
values (as many as defined in your data source in cacti) and then feed that
into the processor. 

I remember that the tricky bit was understanding how all
the custom Cacti components plugged into cacti (i.e, custom data source, custom
this and that ), rather than the feed of the data itself. 
I'll see if I can dig up some sample if you need me to.
