I am trying to start `logstash` via sudo service logstash start
Redirecting to /bin/systemctl status logstash.service

It seems to succeed (service status now is `active` ), however nothing gets written in `logstash` 's own logs, under `/var/log/logstash/logstash-plain.log`
Until a few minutes ago, starting / stopping the `logstash` service did produce output in the above log.

Check /var/log/logstash-stderr.log and /var/log/logstash-stdout.log if they exist. If not, try starting logstash manually (without systemd) to see if anything gets written to your console.
