"Cacti is designed to be a complete graphing solution based on the RRDTool's framework. Its goal is to make a network administrator's job easier by taking care of all the necessary details necessary to create meaningful graphs."

==Nagios Interface==

Runs on an apache2 server, <servername>.

*Custom templates in use: [http://www.goldfisch.at/knowwiki/howtos/cacti Multi-CPU and Disk I/O graphing], [http://code.google.com/p/mysql-cacti-templates/ MySQL template]

==Documentation==

*http://docs.cacti.net/

==Installation==

<pre>apt-get install cacti</pre>
Installs cacti and sets up the GUI on Apache and the MySQL database on installation.

Cacti installation at /etc/cacti/
<br>Cacti scripts at /usr/share/cacti/site/scripts

NetSNMP needs to be installed on each host that is to be monitored (comes installed with Ubuntu).

The SNMP Daemon also needs to be installed and configured to receive requests from the Cacti server.

<pre>apt-get install snmpd</pre>

Then edit the snmpd.conf file and restart the snmp daemon (/etc/init.d/snmpd restart)

[[Snmpd.conf]]

==Adding Templates==

To add a template that you have downloaded, click on the import templates option on the Cacti GUI and follow the instructions. Some templates will have a script associated with them, to run the data queries needed for the graphs. These scripts should be placed in /usr/share/cacti/site/scripts on <servername>.

==Possible solutions if graphs stop updating==

01/06/11 - Poller stopped updating, tried several solutions to fix issue. Unsure which one worked:

* Ran php -q /usr/share/cacti/site/poller.php
* Ran php -q /usr/share/cacti/site/cmd.php
* Restarted Apache2
* Restarted Mysql
* Restarted Cron

Most likely the Cron restart that fixed it as it was complaining about Cron being out of sync, however not 100% sure on that.
