# Cacti Trees
## Trees
A **Tree** can be thought of as a hierarchical way of organizing your graphs.
Each **Tree** consists of zero or more branchs that contain
leaf nodes such as **Graphs**, **Devices** and **Sites**. It's a very powerful
way of organizing your **Graphs**.
Below we can see the current **Trees** we have setup on our Cacti
server. To get to this screen click `Console > Management > Trees`.
From this page you can add or remove **Trees** as required.
Below is how a **Tree** is displayed in **Graph View**. We can see the **Device**
that is being monitored - clicking on this **Device** will result in seeing all
of the **Graph** data generated for the **Device**.
## Creating a Tree
To create a new tree simply click the Add button (+) on the top right hand
corner and enter a name for your **Tree**. After the tree has been created you will
see the below page where you are able to add **Devices** to the **Tree**.
To add devices to the new tree simply drag an available device to the
tree and it will be added to the tree. Cacti currently supports four
`Sort Types`, which can be either inherited, of left to the author to define
inheritance and at what level. See the image below for a visual representation
of how Tree Sorting is accomplished.
###### Table 8-1. Tree Sporting Type Definitions
Field | Value | Description
--- | --- | ---
Name | Name of the tree entry. | The sort order of all trees themselves is always alphabetical
Sorting Type | Manual Ordering (No Sorting) | You may chance the sequence at your will
Alphabetical Ordering | 1, Ab, ab | All sub-trees are ordered alphabetically, unless specifies otherwise (you may chance sort options at sub-tree label)
Natural Ordering | ab1, ab2, ab7, ab10, ab20 | N/A
Numeric Ordering | 01, 02, 4, 04 | Leading zeroes are not taken into account when ordering numerically
End users will not be able to view the **Tree** or it's Graphs until you
publish it. To edit a **Tree**, you will be required to lock it for your use.
The locking is designed to prevent multiple users from editing a **Tree**
simultaneously.
When a Tree is locked, you can drag & drop the **Sites**, **Devices** and
**Graphs** over to the Tree menu. To add a 'Root Branch', simply press the
button to do so, once you have Root Branches, you may right click on the to
create sub-branches on the Tree.
When you single click on a **Site**, the **Devices**, and **Graphs** associated with
that **Site** should appear in their respective sections. You can also type into
the Search fields above the various sections to drill into them. You can also shift-click
and control-click on the objects within a section to drag & drop multiple objects
at one time.
Don't forget to unlock your **Tree** before finishing your editing session.
