Logstash 2.1.1 Fresh ELK Install Errors

Elastic Stack Logstash
1

Hi Guys,

Presently updating my ELK stack a few versions behind to new servers running the latest versions.

At first I got some error:

you might need to reinstall the gem which depends on the missing jar or in case there is Jars.lock then resolve the jars with lock_jars command

no such file to load -- org/apache/httpcomponents/httpclient/4.5/httpclient-4.5 (LoadError)

Theres another thread: Logstash 2.1 fails to start after logstash-output-elasticsearch update -- with some suggestions which I tried amongst other things but that did not fix the problem for me...

I deployed everything from scratch again without running '/opt/logstash/bin/plugin update' and the above error is gone but i get the following error upon starting logstash:

:timestamp=>"2016-01-05T15:58:34.881000+1100", :message=>"Connection refused", :class=>"Manticore::SocketException", :level=>:error}

It doesn't appeared to have stopped things, as logs start ingesting ok as far as I can tell.. but I'm just wondering what it relates to and whats happening etc... so I can get rid of this error. Hadn't had an issue with Manticore previously.

Cheers!

The latter error messages suggests that you've configured Logstash (probably the elasticsearch output) to connect to a port where nothing was listening, at least not at the time. Perhaps you started Logstash before Elasticsearch had started up completely?

ah yep looks like it was just temporary, hasn't appeared again!
