Logstash arcsight integration module (problem)


#1

Hi, I am currently setting up the ArcSight integration module on Logstash so that I could feed security logs to the elastic stack via smartconnectors. Here's the config I am using as instructed in the guide:

bin/logstash --modules arcsight --setup
-M "arcsight.var.input.smartconnector.bootstrap_servers=10.132.111.24:56743"
-M "arcsight.var.elasticsearch.hosts=10.170.41.180:9200"
-M "arcsight.var.kibana.host=10.170.41.180:5601"

Upon checking tcpdumps, i am able to receive the logs from the smart connections but I am receiving this error:

[WARN ] 2018-07-09 19:51:03.834 [Ruby-0-Thread-13: :1] NetworkClient - [Consumer clientId=logstash-0, groupId=logstash] Connection to node -1 could not be established. Broker may not be available.

tcpdump for reference:

Also, i am running on version 6.3 of ELK

Any ideas on how to fix this?
