You probably need some kind of database to store the previous values. It 
may be a plain binary file or a DBMS. Binary files being faster, I 
suggest you have a look at rrdtools which generates and manipulates RRD 
files.

I would wrap the 'check_whatever' plugin into a 'check_store_whatever' 
one that retrieves the state/perf data and store that into the RRD. 
'check_store_xxx' would then check the rate you are looking for 
(computing the derivate of the last N values introduced) and adjust the 
the plugin output and its return code accordingly. With this solution, 
you would also be able to graph the disk usage.
