Changing the question: Can I analyse sFlow and Netflow together? I mean flow-capture is set for Netflow V5. One process collect from a Netflow from a Cisco router, other process collect from a Juniper. I have to analyse theses flow files, but Juniper sends sampling flows! What I have to do about Juniper flows?
