# Graph Overview
|
|
|
|
Almost everything in Cacti is somehow related to a graph. At any time, you can
|
|
list all available graphs by clicking on the Graph Management menu item. While
|
|
it is possible to manually create graphs through this screen, new users should
|
|
follow the instructions provided in the next chapter for creating new graphs in
|
|
Cacti.
|
|
|
|
For users that are familiar with [RRDTool](http://www.rrdtool.org/), you will
|
|
immediately recognize that a graph in Cacti is closely modeled after RRDTool's
|
|
graphs. This makes sense since Cacti provides a user friendly interface to
|
|
RRDTool without requiring users to understand how RRDTool works. With this in
|
|
mind, every graph in Cacti has certain settings and at least one graph item
|
|
associated with it. While graph settings define the overall properties of a
|
|
graph, the graph items define the data that is to be represented on the graph.
|
|
So the graph items define which data to display and how it should displayed,
|
|
and also define what should be displayed on the legend.
|
|
|
|
Each graph and graph item has a set of parameters which control various aspects
|
|
of the graph. Fortunately through the use of graph templates, it is not
|
|
necessary to understand the function of each field to create graphs for your
|
|
network. When you are ready to take on the task of creating your own graph
|
|
templates, extensive field descriptions for both graphs and graph items are
|
|
provided in that section of the manual.
