Sending Logstash logs to /var/log/logstash which is now configured via log4j2.properties.
Configuration OK
Logstash 5.0 introduces a new way to configure application settings for Logstash through a logstash.yml file.
This file is typically located in ${LS_HOME}/config, or /etc/logstash when installed via packages. Logstash will not be able to start without this file, so please make sure to pass in --path.settings if you are starting Logstash manually after installing it via a package (RPM, DEB).
