Where is logstash log

Hello everyone,
I installed logstash with yum. But I can't start it. And the log is empty.
How can i find the error log

Thank you.


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.


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.
