If using sflow - especially that sampling rate - should be no problem. Where will your probes / exporters be? On the cloud switches or your edge - or both? You can always use ntop with libpcap to capture stuff and export those using netflow as well - but if the basic traffic accounting is all you need, stick with the sflow.

I am using an NTOP instances in-house to monitor a 96-port (gigabit ports) HP ProCurve using sFlow. There is an initiative to move our servers to the cloud- either Amazon EC2 or some other hosted Xen-based virtual server offering. In general, I am wondering if anyone has opinion regarding whether it is realistic to monitor all LAN and WAN activity the way we do now (1 out of every 50 packets is sampled) or is the latency going to create problems for us? _______________________________________________ Ntop mailing list [email protected] http://listgateway.unipi.it/mailman/listinfo/ntop <font size="1"> <div style='border:none;border-bottom:double windowtext 2.25pt;padding:0in 0in 1.0pt 0in'> </div> "This email is intended to be reviewed by only the intended recipient and may contain information that is privileged and/or confidential.
