Further, im running rwflowpack as

"sudo /usr/local/sbin/rwflowpack
--sensor-configuration=/etc/nsm/NW-SEC-06-eth0/sensors.conf
--sensor-name=S1 --site-config-file=/etc/nsm/NW-SEC-06-eth0/silk.conf
--archive-directory=/nsm/sensor_data/NW-SEC-06-eth0/silk//archive
--output-mode=local-storage
--root-directory=/nsm/sensor_data/NW-SEC-06-eth0/silk/
--pidfile=/var/log/rwflowpack.pid --log-level=debug
--log-directory=/var/log --log-basename=rwflowpack
"
