For instance on Fedora Core 3, my original Cacti files are located at /var/Once you have the location, remember where it is as you will need it shortly. Now you will need to determine where your original Cacti install is. This is to show you that these are the pre-patched files for Cacti v0.8.6g, there may be other versions available if that is not your version. One of them will look like this 'files-0.8.6g'. In this directory you will find several other directories. Goto the directory that you extracted the Plugin Architecture to. You will of course want to backup your Cacti install first before attempting any add-on modifications. Using the pre-patched files is easiest and most straight forward way to install the Plugin Architecture. I only include the files that are necessary to change, so you don't have to override every file in your Cacti install. With these you can directly override the files already in your Cacti directory. These files are the full install of the necessary files with the patch already applied to them.

The other way is by using the pre-patched full files.

A patch file contains the difference between the original files and the 'new' files, which makes them very small as they only contain exactly what we need to make the changes. The first way is by using the patch files. There are two ways of install the Plugin Architecture. It does not matter in particular to where you download and extract these files to, as we will be moving just the files we need. If all goes well, you should have a folder called cacti-plugin-arch with a few patch files and a folders in it.

Using Unix you can extract it using a command similar to this one, but your milage may vary depending on the Distribution you are running. On Windows there are several ways to extract zips/gzips, just use the program of your choice (ex: Winzip). The Plugin Architecture for Cacti was designed to be both simple in nature and robust enough to allow freedom to do almost anything in Cacti.
