Email alerts based on graph value

[dieselboy]

Hi all, I've recently installed cacti v1.1.24 and found that most plugins are no longer supported.

I would like to receive a notification from cacti when the graph value has reached a value or dropped below a value. I used to use Thold plugin. In the absence of Thold, is there any way in which I can achieve this with cacti v1.1 ? To give context to what I am trying to do, lets say I am polling a routers free memory value. If this free memory drops below a certain amount, I would like to receive an alert.

Thanks

Found that there's a new version of Thold : https://github.com/Cacti/plugin_thold

Admins: the version of Thold stored on this site is not working / not latest.
