I am currently having a small site on a very low end unmanaged freeBSD VPS. The problem is that the provider doesn't give you any method to check your current B/w usage. Can any one here help me in monitoring the B/w usage of my IP? I have heard of MRTG and SNMP. Neither of these two existed on my VPS. I installed them using ports but don't know how to configure them and use them. They are just too much difficult for me. Please help.
