A way to alert suspicous trends?

[Livio Zanol Puppim]

Have a look at RRDTOOL Aberrant Behavior detection using Holt-Winters
algorithim. Maybe it can help you doing something similar to what you want.

A simplier way for your needs, is develop a script wich receives de amount
of steps to lookback at rrdtool, read the values and compare with the real
time from host... Not quite too dificult.
