Forked from https://github.com/didfet/logstash-forwarder-java

Logstash Lumberjack input is not robust enough, this fork replaced Lumberjack protocol to plain TCP.

input {
    tcp {
        port => 5055
        codec => json_lines
        #ssl_cert => "/etc/logstash/server.crt"
        #ssl_certificate_authorities => "/etc/logstash/ca.crt"
        #ssl_enable => true
        #ssl_key => "/etc/logstash/server.key"
        #ssl_key_passphrase => "${TCP_KEY_PASS}"
        #ssl_verify => false
        tcp_keep_alive => true
    }
}

filter {
}

output {
   stdout{} 
}

Just run this command :

java -jar logstash-forwarder-java-X.Y.Z.jar -config /path/to/config/file.json

Go to https://github.com/medcl/logstash-forwarder-java/releases/tag/TCP-Forwarder
