jFlow

Supported – compatible with NetFlowv5/7 and NetFlow v9.

Warning:

jFlow works with NetFlowStart attributes in a different way than traditional flow vendors. The original timestamp of the first packet is preserved even when the flow is exported due to active timeout expiration. As a result, there can be a timeframe of 16:10-16:15 which contains NetFlowStart 14:37. Flowmon can cope with the described approach, but the user needs to be aware of this behavior.
