What I'd like is for it to "look" at my cacti graphs and based on a historical value, send an email if it goes above or below a certain threshold.
For instance, it will look at a traffic graph. It is Tuesday today, so I want it to look at the value for this time last week and if it deviates significantly, send a warning.
However, it would need to be smart enough to not send a warning if last weeks spike was an anomaly and this weeks data is normal.
Can it do this?
