Using latest logstash 5.4.0, getting this error on startup

ERROR StatusLogger No log4j2 configuration file found. Using default configuration: logging only errors to the console.
Sending Logstash's logs to /var/log/ which is now configured via log4j2.properties
log4j:WARN No appenders could be found for logger (org.apache.kafka.clients.producer.ProducerConfig).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.

Command being used is
/logstash/bin/logstash -l /var/log/ --quiet --path.settings /logstash/config --config.reload.automatic -f /logstash/config.d/

Please advice
