I am new to logstash. I am able to write and use simple .conf files and they work. I am trying a more complex and not getting very far. I am getting errors when trying to run logstash config. I ran with --debug and got the below. Any help is appreciated. Thanks in advance.
sudo bin/logstash -f /etc/logstash/conf.d/cisco_syslog.conf --debug
