Hi All,

I am seeing this error in my logstash logs and not sure how to resolve. Some people say to install xpack plugin. My logstash is on version 6.8 and I believe it already comes with xpack by default with this version.

```auto
`[FATAL][logstash.runner] An unexpected error occurred! {:error=>#<ArgumentError: Setting "xpack.monitoring.elasticsearch.hosts" hasn't been registered>, :backtrace=>["/usr/share/logstash/logstash-core/lib/logstash/settings.rb:32:in `get_setting'", "/usr/share/logstash/logstash-core/lib/logstash/settings.rb:64:in `set_value'", "/usr/share/logstash/logstash-core/lib/logstash/settings.rb:83:in `merge'", "org/jruby/RubyHash.java:1342:in `each'", "/usr/share/logstash/logstash-core/lib/logstash/settings.rb:83:in `merge'", "/usr/share/logstash/logstash-core/lib/logstash/settings.rb:135:in `validate_all'", "/usr/share/logstash/logstash-core/lib/logstash/runner.rb:243:in `execute'", "/usr/share/logstash/vendor/bundle/jruby/1.9/gems/clamp-0.6.5/lib/clamp/command.rb:67:in `run'", "/usr/share/logstash/logstash-core/lib/logstash/runner.rb:204:in `run'", "/usr/share/logstash/vendor/bundle/jruby/1.9/gems/clamp-0.6.5/lib/clamp/command.rb:132:in `run'", "/usr/share/logstash/lib/bootstrap/environment.rb:71:in `(root)'"]}`

```

Any ideas please? Thank you

Had to re-install to get it working. Thanks.
