Should be in: /var/log/logstash/logstash-plain.log  
If the log is missing, check the permission on /var/log/logstash/, the user `logstash` should have the permission to write.

Hello,

If systemd is failing to start your logstash service, you may not even have a logstash log depending on the reason.

You need to look at the system log, which will be on `/var/log/messages` or `/var/log/syslog` depending on the distribution.

Try to start it again to generate fresh logs and look the system log for any hints of the issue.
