Hi, I want to implement Nagios with Elastic and I can see notifications from Nagios in Elastic (Kibana). I am trying to install following manual:

> **[Integrating Nagios Checks with Logstash](https://www.elastic.co/es/blog/integrating-nagios-checks-with-logstash)**
>
> How to use the mass of existing Nagios Checks with the Elastic Stack by ingesting check results into Logstash

But when I try last step:  
/usr/share/logstash/bin/logstash --modules nagios --setup

I receive:

How could I solve it?

I have java, logstash, elastic installed from repository (apt). Any ideas? Thanks!!!
