I am brand new to logstash 6.2.3 and struggling with some basics. I have installed it onto CentOS7.
If I run 'systemctl start logstash', I get nothing output to /var/log/logstash/ (but 'systemctl status logstash' reveals that it's apparently running).
If I run /usr/share/logstash/bin/logstash --path.settings="/etc/logstash" I get logs.
How can I fix it so the former operation gives me log output?
My /etc/logstash/logstash.yml file has "path.logs: /var/log/logstash".
