Unable to connect to Logstash from Remote

[James_Nobles]

I've have installed ELK 6.8.3 on CENTOS 6.10. Elasticsearch and Kibana appear to work on so far. I can upload csv files in Kibana and create visualizations.

This issue is sending syslog data to logstash. The goal is to send syslog data from switches, routers and GPON equipment to ELK for dashboards.

This is what i see went starting Logstash. I tried debug logging, which is why you see the first msg, if forgot to change --config.debug back to false

Sending Logstash logs to /var/log/logstash which is now configured via log4j2.properties

My input.conf

input {
    syslog {
        port=> 1024
    }
}

My output.conf

output {
     stdout { }
}

netstat -na|grep 1024(port in the input.conf file)
