HI friends. I use an ELK stack for weeks a a test. All the stack is in version 5.1.1, excepting Logstash in v4.

Kafka is in version 0.10.0.1

After the upgrade, my old conf file isn't working.

Old conf :

input {  
kafka {  
zk\_connect =\> ["192.168.18.15:2181"]  
group\_id =\> "logstash-application"  
topic\_id =\> "ActiveDirectory-Application-Logs"  
reset\_beginning =\> "false"  
consumer\_threads =\> 1  
codec =\> json {}  
}  
}

output {  
elasticsearch {  
user =\> logstash\_internal  
password =\> xxxxxxxx  
hosts =\> ["192.168.18.15:9200"]  
index =\> "logstash-application"}  
stdout {}  
}

I made the changes

new conf:

input {  
kafka {  
bootstrap\_servers =\> ["192.168.18.15:2181"]  
group\_id =\> "logstash-application"  
topics =\> "ActiveDirectory-Application-Logs"  
consumer\_threads =\> 1  
codec =\> json {}  
}  
}

output {  
elasticsearch {  
user =\> logstash\_internal  
password =\> xxxxxxx  
hosts =\> ["192.168.18.15:9200"]  
index =\> "logstash-application"}  
stdout {}  
}

When I lanch the conf file by "./logstash --path.settings /etc/logstash -f /etc/logstash/conf.d/logstash-application.conf " and nothing works.

in the /var/log/logstash/logstash-plain.log I have that error

[2017-01-12T09:46:51,750][WARN][org.apache.kafka.clients.NetworkClient] Bootstrap broker 192.168.18.15:2181 disconnected  
[2017-01-12T09:46:51,814][WARN][logstash.outputs.elasticsearch] Restored connection to ES instance {:url=\>#\<URI::HTTP:0x4338b92c URL:http://~hidden~:~hidden~@192.168.18.15:9200\>}

and the log loops on the message "Bootstrap broker 192.168.18.15:2181 disconnected"

Thanks for your help. There are too many changes with v5.

There is no version 4 of Logstash, what version are you running?
