Prevent Logstash Service logging to /var/log/syslog

Hi, I am trying to work out how and where I can stop the logging of Logstash to the syslog on Ubuntu 16.04.

Instead I would like to have all of the logs for logs for Logstash in a separate file.

I should mention that I'm using Logstash 7.5.1.

Thanks

logstash does not log to syslog by default. It logs to stdout, and you may be using a service manager that cc's stdout to syslog. You could fix that by reconfiguring whatever service manager you are using.
