This is an OpenWrt package feed containing NEMEA system components and IPFIX exporter for exporting flow data.

The figure above shows OpenWRT router with running NEMEA flow exporter ipfixprobe. Since OpenWRT routers usually use big-endian architecture, it is necessary to use a special module endiverter that converts values of UniRec fields to the byte-order that is used on x86 architecture. Due to performace reasons, this conversion is not done automatically in libtrap nor UniRec.

To use these packages, add the following line to the feeds.conf in the OpenWrt buildroot:

src-git nemea https://github.com/CESNET/Nemea-OpenWRT

To install package definitions, run:

./scripts/feeds update nemea
./scripts/feeds install -a -p nemea

The NEMEA packages should now appear in make menuconfig.

NEMEA module ipfixprobe can report statistics using munin client. See this guide.
