Elastic agents not showing up data for custom UDP integration

Hi

I have a Fleet of Elastic Agents running on a fresh k8s cluster (running ECK 8.5.0). I added Custom UDP log integration (default namespace ,Listen port 9512 and Listen address 0.0.0.0,Dataset name: udp.generic) via Kibana but nothing shows up in Logs related to UDP)

lab@master:~$ kubectl get nodes

UDP traffic is coming in the master server as see below

lab@master:~$ sudo tcpdump -i eth0 port 9512 -v -n

Looking on the logs from one of the PODs, I see only that :

root@elastic-agent-quickstart-agent-zzjgc:/usr/share/elastic-agent# cat /usr/share/elastic-agent/state/data/logs/default/filebeat-20221114-4.ndjson

I'm not able of seeing / finding nor indexes neither dataset related to UDP
I'm new on that topic so perhaps I'm doing something wrong here ...

Thanks in advance
