Cacti strives to be easy to use yet it contains a
lot of power under the hood
3
Cacti Provides...

• Graph templates
• Data queries
• Custom data input
• Script server
• User and access control
• Exportable templates

4
Graph Templates

• Allows you to make a graph and apply it to
  multiple devices
• Updating the template affects all of its graphs

5
Data Queries

• Have Cacti query a device for a list of things to
  graph (interfaces, disks, etc)

6
Custom Data Input

• Graph the output of any script or command
• Allows you to graph virtually anything

!/usr/bin/perl open(PROCESS, "cat /proc/meminfo
grep -w ARGV0 ") foreach (ltPROCESSgt) if
(_ /(ARGV0.\s)(.0-9)( kB)/) print
2 close(PROCESS)
7
Script Server

• Read and write data to a script using
  bidirectional pipes for reduced polling overhead
• The default Windows disk and CPU scripts use this
  method

8
User and Access Control

• Create users that have access to specific areas
  within the interface
• Create restricted users with access to certain
  graphs
• Give customers logins to see their own graphs

9
Exportable Templates

• Export any template in Cacti to an XML file that
  can be imported with any installation
• Allows templates to be shared within the
  community
• Makes it easier to find graphs for less common
  devices
