It may help to think of sFlow as "Shimmer" - it is both a floor wax *and* a dessert topping. An sflow agent can be configured to send flow samples (similar to netflow) or counter samples to an sflow collector, and it does appear that ntop can receive and do something useful with sflow counter samples. The Very Nice Thing about an sFlow counter sample is one gets all the counters in one shot - so instead of having to query each stat for an interface one at a time via SNMP, they all "just arrive" together in the same sFlow PDU. In fact, multiple counter samples, each from multiple interfaces, can be carried in the same sflow PDU making it even that much more efficient than querying via SNMP. rick _______________________________________________ Ntop mailing list [email protected] http://listgateway.unipi.it/mailman/listinfo/ntop
