Integrate logstash with zabbix 2.2 for getting alerts

OS: Ubuntu 14.04

I would like to Integrate logstash with zabbix for getting alerts while logstash getting error messages from openstack node logs. I have already configured ELK stack and Zabbix which are working calm. I just need to generate a trigger in zabbix when kibana receive a error log by using zabbix-sender/zabbix trapper.

I found a few posts,but could you please let me know in which directory location logstash-2-zabbix config file with input/filter/output to be created ? Please enlighten me.

Thanks in anticipation @theuntergeek

Perhaps this post could be of some help, or search for "zabbix" in the navigation bar at the top of the browser pane.

If you already have the Elastic Stack running, then you should know where your logstash.conf file is. If you installed via package, it would be in /etc/logstash/conf.d

Thanks for the response @theuntergeek. I will try as mentioned.
