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

</div>We're building out a monitoring system for a large amount of servers with 90%<br>
having diskgraphs, it would be a dounting task to look at all of them manually.<br>
It's quite pro active if you can be warned on suspicious trends.<br>

<br>
</div>Good tip, I'm going to have a look at this, ... but having to build this myself<br>
it's going to end up on the bottom of my extensive todo list:)<br>
