Cento - Is it possible to send sampled rate

Hello,

We are using Cento to send netflow to a system that requires us to send at a sampled rate.  Is this possible with Cento?  I do not see the option listed in the Cento help file.

I see it is possible with nprobe:

[--sample-rate|-S] <pkt rate>:<flow rate>
 | Packet capture sampling rate and flow
 | sampling rate. If <pkt rate> starts with
 | '@' it means that nprobe will report
 | the specified sampling rate but will
 | not sample itself as incoming packets
 | are already sampled on the specified
 | capture device at the specified rate.
 | Default: 1:1 [no sampling]

If so, can we define a sampled rate for one collector and not sampled to another collector?

Kind regards,

Jesse
