Hello, I have installed x-pack for Logstash. When I try to run configuration file, I get the following error: [FATAL] 2017-10-04 15:41:55.607 [LogStash::Runner] runner - An unexpected error occurred! {:error=\>#\>, :backtrace=>["/usr/share/logstash/vendor/bundle/jruby/2.3.0/gems/x-pack-5.6.2-java/lib/monitoring/monitoring.rb:102:in`after\_initialize'", "/usr/share/logstash/logstash-core/lib/logstash/event\_dispatcher.rb:34:in `block in fire'", "/usr/share/logstash/logstash-core/lib/logstash/event_dispatcher.rb:32:in`fire'", "/usr/share/logstash/logstash-core/lib/logstash/agent.rb:77:in `initialize'", "/usr/share/logstash/logstash-core/lib/logstash/runner.rb:438:in`create\_agent'", "/usr/share/logstash/logstash-core/lib/logstash/runner.rb:351:in `execute'", "/usr/share/logstash/vendor/bundle/jruby/2.3.0/gems/clamp-0.6.5/lib/clamp/command.rb:67:in`run'", "/usr/share/logstash/logstash-core/lib/logstash/runner.rb:232:in `run'", "/usr/share/logstash/vendor/bundle/jruby/2.3.0/gems/clamp-0.6.5/lib/clamp/command.rb:132:in`run'", "/usr/share/logstash/lib/bootstrap/environment.rb:71:in `'"]} I have updated the logstash.yml file as per: [https://www.elastic.co/guide/en/x-pack/master/monitoring-logstash.html](https://www.elastic.co/guide/en/x-pack/master/monitoring-logstash.html) Any help appreciated. ---

What does the config file look like? ---

My configuration in logstash is as below: xpack.monitoring.elasticsearch.url: "[http://localhost:9200](http://localhost:9200)" xpack.monitoring.elasticsearch.username: "logstash\_system" xpack.monitoring.elasticsearch.password: "changeme" I can also authenticate with this user as below: curl -u logstash\_system '[http://localhost:9200/\_xpack/security/\_authenticate?pretty=true](http://localhost:9200/_xpack/security/_authenticate?pretty=true)' Enter host password for user 'logstash\_system': { "username" : "logstash\_system", "roles" : [ "logstash\_system" ], "full\_name" : null, "email" : null, "metadata" : { "\_reserved" : true }, "enabled" : true } When I do plugin list for logstash, it shows up as installed. I installed x-pack version 5.6.2 and it shows up in Gemfile as below: gem "x-pack", "= 5.6.2" I enabled xpack for Kibana and ES as well, I see these in Kibana in monitoring tab. The only one I can't get working is Logstash. ---

So you are specifically having issues getting monitoring working? ---

Since installing x-pack, Logstash doesn't work anymore. When starting logstash- my pipelines fail due to the error above. So issue is with Logstash working after x-pack installation. The reason why I installed x-pack is to get monitoring of Logstash in Kibana. But now it seems with xpack enabled, I cant get Logstash to work anymore, unless I remove x-pack. Would be great to have x-pack working though! ---

From the version numbers you have, it looks like you tried to install _x-pack 5.6_ into _logstash 6.0 (beta)_ That will definitely not work. You need to install the correct version of x-pack to match your version of logstash. ---

Thanks for the info, I thought x-pack 5.6.2 would work with Logstash 6.0 but I see now this is not the case. I will upgrade x-pack and come back if I have any issues. ---
