Cacti Customisation

Introduction

  • Cacti is a PHP based application that runs under and Apache Web

Server and uses MySQL to store its data. Access to the application is controlled by CROWD. Cacti is accessed internally by DANTE staff and externally by users via the Tools Portal.

  • This presentation seeks to give an overview of Cacti and to highlight

possible routes of customisation.

Cacti Customisation – Round-Robin Database (RRD) Files

Advantages:

  • RDD Files remain static in size.
  • Powerful graphing tool.

Disadvantages:

  • Relies on RRDTool. (although there are some Perl and Java libraries out there):
  • It requires 3 valid values before you see a monitoring result (3x5=15 minutes).
  • RRD rounds data by default. So the yearly graph doesn't show the peaks that the daily

graphs do. (This can be fixed by not graphing the average values but the maximum values.)

  • RRD averages data when putting daily values into weekly values, weekly into

monthly and monthly into yearly.

  • Changing the monitoring frequency (aka "heartbeat") is not possible either without

throwing away the data and starting from scratch either.
