# Viewing Graphs
|
|
|
|
## Background
|
|
|
|
Cacti, when it was first invented in 2001 by Ian Berry, his vision was to make it
|
|
the fastest and easiest way to view and render Network Monitoring **Graphs** for
|
|
people in the Network, Site, and Data Center Operations Space. As such, it's focus
|
|
from the very beginning was on render just one thing, **Graphs**. So, as such,
|
|
the second **Top Tab** on a Cacti system is the **Graphs** tab.
|
|
|
|
## The Graphs Top Tab
|
|
|
|
The **Graphs** **Top Tab** has a few personalities. They include:
|
|
|
|
- **Tree View**
|
|
|
|
Allows Cacti Users to view **Graphs** in the form of hierarchical **Trees**.
|
|
These **Trees** are generally constructed by the Cacti Administrator and are
|
|
controlled either at the **User** or **User Group** level.
|
|
|
|
- **Preview View**
|
|
|
|
The **Preview View** provides a view of all **Graphs** that a Cacti User has
|
|
access to. **Table Filters** are provided to constrain the list of **Graphs**
|
|
returned to the page.
|
|
|
|
- **List View**
|
|
|
|
The **List View** allows the Cacti user to Create their own **Preview Page**
|
|
by allowing them to select graphs from various pages, and then finally view
|
|
those pages from the **Preview View**.
|
|
|
|
The way these various personalities appear in Cacti is somewhat different
|
|
depending on your Theme. Review the two images below, for how you navigate to
|
|
the various **Graph View** modes.
|
|
|
|
In this first image, we see the way the **Graph View** options are displayed to
|
|
the end user. This is the layout of the Classic, Modern and Dark themes.
|
|
|
|
|
|
|
|
In this second image, you can see the way the **Graph View** page will appear for
|
|
users of the Paw, Paper-Plane, and Sunrise themes.
|
|
|
|
|
|
|
|
## Graph Manipulation and Options
|
|
|
|
Once you can view the **Graphs**, there will be a Filter Panel that will provide
|
|
you multiple options to limit your view of them. Below, you can see an image of
|
|
that Filter Panel.
|
|
|
|
|
|
|
|
From this sub-panel, you can do the following:
|
|
|
|
- Search by regular expression
|
|
- Select one to many, or all **Graph Templates** to view
|
|
- Specify the number of Graphs per Page
|
|
- Specify the number of columns to Display
|
|
- View either Legendless Thumbnails or full Graphs with their legends
|
|
- Set various Preset Time-spans, or select a Time Range
|
|
- Shift the Time either forward or backward by the Shift Time-span
|
|
|
|
Once you have the Filter where you like it from a Columns, Thumbnails, and Graphs
|
|
per Page setting, you can press the `Save` button, if you have the correct
|
|
permissions and save those defaults for your next login.
|
|
|
|
Depending again on permissions, to the right of the **Graphs**, you will find a
|
|
number of action icons that allow you to operate on the **Graphs**
|
|
|
|
The image below shows what that might look like if you have the **Thold** and
|
|
**QuickTree** **Plugins** installed.
|
|
|
|
|
|
|
|
From top to bottom, the Graph Action Icons do the following.
|
|
|
|
Name | Description
|
|
--- | ---
|
|
Graph Details | Allow you to perform precision zooming, view RRDtool debug information and perform CSV exports of your Graph Data.
|
|
CSV Export | Allows you to directly CSV Export your Graph Data
|
|
Realtime View | Allows you to view your Graphs at down to a 1 second granularity either in place, or in a pop-up Window
|
|
Spike Kill | Allow you to clear up Spikes and Gaps in your Graph
|
|
Create Threshold | Create a Threshold for the Graph
|
|
Add to QuickTree | Allow you to select Graphs to add to Trees by simply tooling around the Graphs page.
|
|
|
|
## Graph Zooming
|
|
|
|
Cacti also has a powerful Graph Zoom interface built in. You can discover
|
|
what it allows you to do by simply right clicking in the Graph area. When
|
|
zooming, you will zoom all the **Graphs** on a page. It's quite powerful.
|
|
|
|
|
|
|
|
There are many options for the Zoom menu. Instead of explaining them here
|
|
try them out for yourself.
