Nagios - can it do what I want?

[Soop]

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?

You might want to ask the same question on the Nagios forums

If people don';t know whether Nagios does it, is there anything else that would?

Take a look at the THOLD plugin. This would probably do it with baselining

thold does this quite well..... i have a slightly modified version of thold that i use for this purpose. using 1 minute polling we know of any deviations on any of our upstreams within 2 mins at the latest

THold does seem to be what I'm looking for. Is there any documentation? What looks like the official page just tells me to come here.
