Hi,

I have running two logstash server on different kubernetes cluster with the lumberjack input/output plugin.

My config.

Client:

output {  
lumberjack {  
hosts =\> ["[XXXXXXXXXXXXXXXXXXXXXXXXXXXX-CCCCCCCCC.us-east-1.elb.amazonaws.com](http://XXXXXXXXXXXXXXXXXXXXXXXXXXXX-CCCCCCCCC.us-east-1.elb.amazonaws.com)" ]  
port =\> 6782  
ssl\_certificate =\> '/etc/logstash/certs/server.crt'  
}  
}

Server:

input {  
lumberjack {  
port =\> 6782  
ssl\_certificate =\> '/etc/logstash/certs/server.crt'  
ssl\_key =\> '/etc/logstash/certs/server.key'  
}  
}

Client log:

10:05:23.081 [[main]-pipeline-manager] ERROR logstash.outputs.lumberjack - All hosts unavailable, sleeping {:hosts=\>[], :e=\>#\<RuntimeError: Could not connect to any hosts\>, :backtrace=\>["/usr/share/logstash/vendor/bundle/jruby/1.9/gems/jls-lumberjack-0.0.26/lib/lumberjack/client.rb:31:in `connect'", "/usr/share/logstash/vendor/bundle/jruby/1.9/gems/jls-lumberjack-0.0.26/lib/lumberjack/client.rb:24:in`initialize'", "/usr/share/logstash/vendor/bundle/jruby/1.9/gems/logstash-output-lumberjack-3.1.5/lib/logstash/outputs/lumberjack.rb:86:in `connect'", "/usr/share/logstash/vendor/bundle/jruby/1.9/gems/logstash-output-lumberjack-3.1.5/lib/logstash/outputs/lumberjack.rb:49:in`register'", "org/jruby/RubyArray.java:1613:in `each'", "/usr/share/logstash/logstash-core/lib/logstash/output_delegator_strategies/legacy.rb:17:in`register'", "/usr/share/logstash/logstash-core/lib/logstash/output\_delegator.rb:41:in `register'", "/usr/share/logstash/logstash-core/lib/logstash/pipeline.rb:281:in`register\_plugin'", "/usr/share/logstash/logstash-core/lib/logstash/pipeline.rb:292:in `register_plugins'", "org/jruby/RubyArray.java:1613:in`each'", "/usr/share/logstash/logstash-core/lib/logstash/pipeline.rb:292:in `register_plugins'", "/usr/share/logstash/logstash-core/lib/logstash/pipeline.rb:301:in`start\_workers'", "/usr/share/logstash/logstash-core/lib/logstash/pipeline.rb:226:in `run'", "/usr/share/logstash/logstash-core/lib/logstash/agent.rb:398:in`start\_pipeline'"]}

Can you tell me what I'm doing wrong?

Thanks in advance.

Regards, jerry

This error message suggests a network problem. Have you verified that you can connect to the host and port via e.g. telnet?

Hi Magnus,

Yes, I have verified with telnet. I can connect to the LoadBalancer via telnet.

telnet [XXXXXXXXXXXXXXXXXXXXXXXXXXXX-CCCCCCCCC.us-east-1.elb.amazonaws.com](http://XXXXXXXXXXXXXXXXXXXXXXXXXXXX-CCCCCCCCC.us-east-1.elb.amazonaws.com) 6782  
Trying [XXX.XXX.XXX.XXX](http://XXX.XXX.XXX.XXX)...  
Connected to [XXXXXXXXXXXXXXXXXXXXXXXXXXXX-CCCCCCCCC.us-east-1.elb.amazonaws.com](http://XXXXXXXXXXXXXXXXXXXXXXXXXXXX-CCCCCCCCC.us-east-1.elb.amazonaws.com).  
Escape character is '^]'.  
^CConnection closed by foreign host.

If I use for test the public IP from the LoadBalancer then it works.

Regards, jerry
