[j-nsp] Good J-flow Collector

[Amr]

Dear All,
            I need to configure J-flow on My M120 Router , Anyone knows a
good Collector program in order to collect the data from the M120 router ?

I need to be able to collect information about the traffic that flow on My
M120 Router , the average traffic is about 500 Mbps


Thanks In Advance


Regards
Amr
