NimbostratusF5 sFlow with ManageEngine Netflow
Hi All,
I've spent a bit of time trying to look into this: is anyone using ManageEngine NetFlow Analyzer as a target for sFlow data from an F5?
Thanks.
benniehanas_239I tried running sflow to ManageEngine and I get that F5 is sourcing an incorrect self-IP that isn't in the traffic path for sflow via MPLS. It is sourcing an IP that goes out to the Internet even though routing takes sflow traffic across internal MPLS for 10.10.X.X addresses. This causes a new device in OpManager to be built which gives no info at all as SNMP isn't enabled on that sourced IP and there are no interfaces to look at for monitoring. This is very weird and I haven't been able to see any documentation on this issue.
- Using tcpdump I can see the packets from the F5 coming to my Netflow box, but Netflow does not register the packets. I'm not sure why this is occurring but I believe we are going to look into other products for this task. Thanks!
netvis_66639I can't help you with ManageEngine, but you can verify that you are getting data using sflowtool/sFlowTrend:

Are you having trouble reading it in? Send us a packet capture and we'll test it for you.
