I am trying to setup Syslog-NG t send output to Kakka. I am running ubuntu 18.04, Syslog-NG version 3.37. This is my syslog-ng.conf ( I have #scl.conf because if I don't it tries to install kafka-java) @version: 3.37 @define kafka-implementation kafka-c #@include "scl.conf" destination d_kafka { kafka( bootstrap-servers("127.0.0.1:9092") topic("{incoming}") ); }; This is the error when I try and run sudo syslog-ng Error parsing config, syntax error, unexpected LL_IDENTIFIER, expecting '}' in /etc/syslog-ng/syslog-ng.conf:6:3-6:8: 1 @version: 3.37 2 @define kafka-implementation kafka-c 3 #@include "scl.conf" 4 5 destination d_kafka { 6-----> kafka( 6-----> ^^^^^ 7 bootstrap-servers("127.0.0.1:9092") 8 topic("{incoming}") 9 ); 10 }; Any help will be appreciated.
