Is there any? What I really need is to create some graphs in Nagios with some plugin that has a feature of sending notifications when graph line exceeds threshold value in some time frame (let's say if value is beyond 3 for 5 minutes, send a notification).
And I mean real Nagios plugin, not bonding with some other tool like Cacti or similar.
I have read instructions and readme files in evey graph plugin but haven't found the feature I need. Excuse me if I've missed it. It would be really nice if someone could tell me if there is any plugin of such sort.
