I am creating a custom output plugin and use it on logstash. I am using packetfu library in my plugin definition when I am running plugin it fails because it couldn't load packetfu. Where do I have to define packetfu so i can use it.. Installing locally didn't help.
[root@elastic ~]# /usr/share/logstash/bin/logstash -f /root/udp_spoof.conf
