Max Threshold minus 10 degrees

[C@ctiUser]

Perhaps this is out here somewhere and I am just not seeing it, but I was wondering if it is possible to take the value cacti is getting for a max threshold and subtract 10 degrees from it and use this as a template. For instance I have a server that Cacti pulls the Max Threshold of 95 degrees. I would like to statically set the "High threshold" to 85 degrees so that I get an email when the temperature is at or above 85 degrees, this way I have some time to work on the problem before the server hits the critical mark and possibly shuts down. Thanks

Yes, there is a fairly stable version 0.42 that includes an RPM provision. However, it may not work exactly as documented when the next release is done.

What is the name of this? Would this by chance work on windows? Thank You Again.

RPN Expression. It works for everyone.

Perhaps this is a dumb question but is there a way to go |Threshold|-10 for the High Temp section in setting up the Threshold alert? Similar to how |host_name| is the Name of the server. I have taken a look at RPN and this seems a little too complicated for me to use, not even too sure how to install this and configure it on windows. I just started using Cacti a little while ago. But as stated before I still appreciate the Help.

Trying to use the following RPN Expression for a Thold, and it does not work. Am I doing this wrong - and if so, could you point me to some documentation on how to use RPN Expressions in Thold?
