Netflow Data From a Mirror Port Error

ppkcppkc

Big Time
Hi there,

atm my setup is 1 central server and 2 sensors both on mirror ports with Netflow on.

I am getting Netflow info to show only from my central servers built in sensor. The data itself is being sent from both other sensors to the central server but it is not displayed - an Error is shown:

stat() error '/var/cache/nfdump/flows//live/564D8533C8A348D24C08BF0477FC8516/2014-07-01/nfcapd.201407010945': File not found!

This file actually exists. Has anyone had this issue? Thanks lots!

  • I have not seen exactly this before but I have seen similar. Could you by any chance share your sources config from /etc/nfsen.conf and your fprobe settings from your sensors?

    Thanks!

    So it sorted itself out. I run an update, rebuilt my mysql tables, reconfig and the issue was gone.
