I just re-visited your post. I misunderstood on first visit, because you're using the term "Add-On". This is related to some code tweaking to extend cacti's capabilities. Examples are
Thold,
Monitor etc. pp.
There's another "build-in" method to make cacti collect and display data based on
templates. It is possible to define templates on your own. When finished, you may
Export them, using the
Export Templates function on the nav bar at the lower left side. Usually, the resulting XML file is posted to the forums. Anyone using at least the same or newer cacti version is able to import from this XML file. This will produce all the
Graph|Data|Host Templates,
Data Input Method and/or
Data Query Definitions and the like. To Import, please download the XML to any place and goto
Import Templates. Locate the downloaded file and
Save
But as soon as self-made scripts (to gather data) come into account, you'll not only need the XML files but those scripts as well. The scripts usually go into <path_cacti>/scripts.
That should be enough for starting (yes, there are more options with Data Queries).
