In Cacti, graphs can be organized in a hierarchical tree structure. Each graph tree contains zero or more branches containing either hosts or individual graphs. Even each node of the tree could have multiple branches. In this way, we can organize graphs functionally.
You can access Graph Trees under Management. In the Graph Trees page, click on the add button for a new graph tree.
Choose a name and select a sorting type from the drop-down box. There are four sorting types in the drop-down box:
Manual Ordering: Each graph/device that is added can be re-ordered within the tree/branch
Alphabetic Ordering: Each graph/device is ordered alphabetically
Numeric Ordering: Each graph/device is ordered numerically
Natural Ordering: Alphanumeric ordering taking into account numeric increasing
You can choose the sorting that will fit your requirements
In this example, I use a tree name LinuxBox 192.168.59.128 and sorting type Manual Ordering.
