You could take a look at sysstat and the graph with whatever tool you 
wish. I use kSar to plot.

By default, the sysstat output is kept for a week, but you could write 
scripts to keep the information for as long as you wished.

sysstat rpm on CentOS 6.4: sysstat-9.0.4-20.el6.x86_64
kSar web site:             http://sourceforge.net/projects/ksar/

. . . just my two cents
