My questions is what would be easier to implement, rrd or snmp? I'm not familiar with both. I was able to get the rrd file but im having problems extracting/reading the logs. I tried snmp but it seems its difficult to gether historical logs (1 day) stats using snmp.
rrd is a database to store performance data (or other values). snmp is a protocol to collect data from the LB. So it's not rrd or snmp, it's rather both.
Please take a look at cacti. It creates nice graphs, offers a decent web gui and there is a lot of information available at devcentral. Just search for cacti.

With the nectar plugin you can even send reports via e-mail (http://docs.cacti.net/plugin:nectarpurpose).
