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
