Adding devices to the Cacti tree


The Cacti tree lists sub-trees, hosts, and graphs in a tree-like interface. It is the main user interface for the Graphs tab. There can be more than one tree, which allows for a granular definition of the tree structure. Before creating the Cacti tree, think about a good structure for it. Changing the tree later can involve quite a bit of manual work.

With the new 1.0 version of Cacti, the Cacti tree has undergone a major change from the 0.8 version. Previously, the tree management page was built using a static HTML page, which caused a large amount of work when managing large Cacti deployments. Version 1.0 introduced a dynamic JavaScript-based interface with drag-and-drop support, so the tree creation process and, especially, rearranging devices is now a lot easier.

Creating a tree

Cacti already has a default tree defined, which holds the localhost. You are going to leave this default tree empty and create your very own tree.
