My company uses OpManager NetFlow Monitor to help look at the traffic passing our routers and Sophos Firewalls. The data being displayed in OpManager Netflow is not consistent with the data shown on the Sophos dashboard, or the SNMP portion of OpManager.
My best guess as to why, is that the sample rate of NetFlow in Sophos is not 1:1. Is there any way to see what the sample rate is on the Sophos box, and change this to another value if we think our box can handle the added load of an increased sample rate?
