How can I modify cacti in order to use some SNMP variables that are not included standard (eg : load average, memory information, harddrives etc)

You create a Data Input to use with the Data Source you want to track.

0.6.4 and earlier did not have internal SNMP support and the linux snmpget always gives you the OID in the output. You will have to write a small shell script that uses snmpget and sed to get just the output value that you want.

0.6.5 has native SNMP support. You should be able to define a new SNMP data input that fetches what you want.
