How hard would it be to add an rrdgraph for modem signal strength?
-
I'm interested in some how adapting this:http://forums.cacti.net/viewtopic.php?t=8688 idea for my sb5100, and I'm wondering how hard it would be to parse the signaldata.html file (from what I can tell, perl isn't installed) and generate data for rrdgraph. I have no idea where to start and any tips/guidance/help would be appreciated.

even if perl is not installed, PHP is installed and can do almost everything perl can (not sure what modules are installed on PFsense though).
So if there is a perl script for this, look at the code and try to convert it to PHP (some help can be found here: http://www.cs.wcupa.edu/rkline/perl2php/)
