Do I need MRTG for Motorola Canopy?

I bought a Motorola Canopy 9000APC and 9000SMC.

Do I need to buy something called MRTG in order to use them? I think MRTG has someting to do with monitoring them? Not sure.

Thanks,

MRTG is a free open source software project designed to poll data providing resources and graph the result.

It is toally unrelated to the functionality of Moto Canopy.

Some Canopy administrators use it to monitor usage and performance though.
