Hello,

I'm trying to use logstash-output-gelf to send logs to a Graylog instance.  
I've installed a fresh logstash-6.0.0 and installed the plugin with :

> logstash-plugin install logstash-output-gelf

No error at this point.

I've added this block on my logstash config file (that worked out with rubydebug) :

> gelf {  
> host =\> '192.168.56.101'  
> port =\> 12201  
> }

Logstash fails with this error when I run it :

> [2017-11-30T11:11:29,507][FATAL][logstash.runner] An unexpected error occurred! {:error=\>#\<NoMethodError: undefined method `time' for nil:NilClass>, :backtrace=>["/tmp/logstash/logstash-core/lib/logstash/timestamp.rb:13:in `\<=\>'", "org/jruby/RubyComparable.java:150:in `=='", "/tmp/logstash/vendor/bundle/jruby/2.3.0/gems/logstash-output-gelf-3.1.4/lib/logstash/outputs/gelf.rb:146:in `block in receive'", "org/jruby/RubyHash.java:1343:in `each'", "/tmp/logstash/vendor/bundle/jruby/2.3.0/gems/logstash-output-gelf-3.1.4/lib/logstash/outputs/gelf.rb:145:in `receive'", "/tmp/logstash/logstash-core/lib/logstash/outputs/base.rb:92:in `block in multi_receive'", "org/jruby/RubyArray.java:1734:in `each'", "/tmp/logstash/logstash-core/lib/logstash/outputs/base.rb:92:in `multi_receive'", "/tmp/logstash/logstash-core/lib/logstash/output_delegator_strategies/legacy.rb:22:in `multi\_receive'", "/tmp/logstash/logstash-core/lib/logstash/output\_delegator.rb:49:in `multi_receive'", "/tmp/logstash/logstash-core/lib/logstash/pipeline.rb:538:in `block in output\_batch'", "org/jruby/RubyHash.java:1343:in `each'", "/tmp/logstash/logstash-core/lib/logstash/pipeline.rb:536:in `output\_batch'", "/tmp/logstash/logstash-core/lib/logstash/pipeline.rb:481:in `worker_loop'", "/tmp/logstash/logstash-core/lib/logstash/pipeline.rb:439:in `block in start\_workers'"]}

Any idea on what I did wrong ?

Cheers.

I've just tried with previous version (5.6.4) and it works as expected.

Hi,  
I would say look to get this issue added here: [https://github.com/logstash-plugins/logstash-output-gelf/issues](https://github.com/logstash-plugins/logstash-output-gelf/issues)  
As this could be something that other users will be effected by. Thanks.
