When doing system-monitor with Cacti, can you execute an arbitrary script when a threshold is reached, yes or no?
If yes, how?
 I was planning on using the Cacti plugin Thold but as far as I can tell this only allows you to email someone when a threshold is reached... not execute an arbitrary script.
I found an official post from the author of Thold which talks about "Alternate alerts... running scripts" which is the functionality I need (executing an arbitrary script when a threshold is reached).
But other than that post, I can't seem to find any examples or posts on whether 'executing an arbitrary script when a threshold is reached' is a working feature and/or how to configure said feature.
