Hi,
I have some vSphere 5.1 VDS's sending IPFIX net flow to our nfsen server.
(nfsen v 1.3.5)
I am running nfdump Version: 1.6.9 with the IPFIX patch posted on this list on
the 13/4/2013 by Peter.
I am receiving the net flow data and below is the output in raw form after I
applied the patch. You will notice that "first" and "last" are set on
1970-01-01 10:00:00. There is an up to date time in the last variable of the
packet in "received at".
NFsen can read the data and it is correct (I compare it to data we pull via
snmp) however NFsen /ndump are formatting the data with timestamps of
1970-01-01 10:00:00 instead of the actual time.
I notice this has been raised on various sites but I have not seen a fix. I
don't mind testing some patches if they become available to fix up this
timestamp issue.
