Re: Snapshots of Sflow

Hi Alex,

At least for the time you enable sflow export on your device you have to
have an outside box to receive the information.

Further I'm not sure if a "snapshot" would be of much help. Keep in mind
that sflow doesn't keep any counters on the devices itself but rather
samples the packets as they come by. That means that every analysis has
to be done externally (by a collector).

You could probably enable the collecting periodically for a certain
amount of time and analyze the data for the given time frame. But I'm
not sure if I understand correctly what you would want to see? Could you
elaborate what you mean by flows over as?

Kind regards
