We are testing upgrade from Logstash 1.4.2 to 2.3.3 and seeing a lot of this error in the logstash.log:

{:timestamp=\>"2016-06-21T15:41:12.868000-0500", :message=\>"Ruby exception occurred: LogStash::Timestamp can't be coerced into Fixnum", :level=\>:error}

We have a lot of configs under /etc/logstash/conf.d. Can somebody point me in the right direction on how to troubleshoot this issue?

Thanks,

Andrew

I isolated this error to this code in our config:

ruby {  
init =\> "require 'time'"  
code =\> "event['[metrics][server\_lag]'] = Time.now.to\_i - event['@timestamp']; event['[metrics][server\_time]'] = Time.now.to\_i"  
}

Fixed the code and the error wen away:

ruby {  
init =\> "require 'time'"  
code =\> "event['[metrics][server\_lag]'] = Time.now.to\_i - event['@timestamp'].to\_i; event['[metrics][server\_time]'] = Time.now.to\_i"  
}
