Yeah, I don't think a Filebeat module for ISE logs exists, but there is an Elastic Agent integration, my suggestion would be to use a Custom Kafka Logs integration to get the logs from Kafka and reroute them to the Cisco ISE ingest pipeline to parse it.
I've described the steps on the OP other post: Does Elastic Agent support kafka as an input? - #4 by leandrojmp
@Priyanka_chauhan , I recommend that you use the Elastic Agent and check the answer on your previous post about it.
