i have couple of problem. The [logstash document](https://www.elastic.co/guide/en/logstash/current/dir-layout.html) says logs saved in **/var/log/logstash** folder,  
but in my case log is saved in **/usr/share/logstash/log** folder ? so why is that ?

Other problem i am having is ubuntu syslog size keep on increasing and when i check it contail full of logstash logs. so is there way to stop syslog accumulating syslog file ?

my syslog file size is currently 16G, 3 hours ago it was 12G

Check that you don't have debug turned on in you logstash.yml file and there may be a symbolic link from /var/log/logstash to /usr/share/logstash/log

I have had similar "issues" with Elasticsearch. I ended up creating my own `log4j2.properties` file so I could disable syslog logging.

[EDIT]  
Actually looks like that was only to change log level...

Is there any other way, rather than changing the log4j file?
