Hi all

I have a simple logastash.conf at the moment. I receive from winlogbeat and I store information in the Elasticsearch.

Now I'd like to add a new output to syslog. I'd like to send only the log of the administrator users to syslog.

How could implement this? I think the following 2 solutions

1. Winlogbeat send information with the field that show the administrators users (at the moment I don't found a solution for this; I see the processor but it isn't possible to use a script to do discover of administrator of the system)
2. Logstash receives information from winlogbeat and for any user check if the user is administrator of the system with a script code(I see that in logstash there is the ruby code that I could use)

Do you have other suggestion?

Thank you  
Franco

Simply try LOGSTASH OUTPUT PLUGIN  
[https://www.elastic.co/guide/en/logstash/current/plugins-outputs-syslog.html](https://www.elastic.co/guide/en/logstash/current/plugins-outputs-syslog.html)

You can define many parameters there.

**! It is necessary install this plugin to logstash !**

```
/usr/share/logstash/bin/logstash-plugin install logstash-output-syslog
```

Very useful staff in logstash is **@metadata** field. You can add field based on some condition.. this @metadata field will not be stored to a document. But you can use this field in conditions in **output section** in logstash.
