Elastic Stack Logstash
1

Hello,
I just installed logstash 5 and when I run it with the following configuration I have an error message

/usr/share/logstash/bin/logstash -f /etc/logstash/conf.d -l /var/log/logstash --verbose --path.settings=/etc/logstash/

ERROR StatusLogger No log4j2 configuration file found. Using default configuration: logging only errors to the console.
Sending Logstash logs to /var/log/logstash which is now configured via log4j2.properties.
2016-10-26 02:37:40,628 Api Webserver ERROR No log4j2 configuration file found. Using default configuration: logging only errors to the console.

I do not see the problem

I have the same problem but under Windows
Log4j file is not find, but it exist in E:/MCO/TDB/bin/logstash-5.0.0/config/log4j2.properties

The log show an error on "java.net.UnknownHostException: E".
It seems that E is the drive of the log4j path.
