Hi all, I am trying to find the hostname inside the javascript script code.  
I tried to get it using the "os" module, but it seems that it is not available.  
Are there any other options to achieve this?  
Also, where can I see the whole available modules?  
Thanks

hello @Saeed_Ektesabi2 , welcome to the Elastic community!

I'd need some more information in order to answer you questions.

What's the beat you are trying to add a processor script to? What's the version you are using?

What do you mean exactly with the "os" module?

Are you referring to the Filebeat/Metricbeat modules?

Here you can find the modules lists for both:

> **[Modules | Filebeat Reference \[8.3\] | Elastic](https://www.elastic.co/guide/en/beats/filebeat/8.3/filebeat-modules.html)**

> **[Modules | Metricbeat Reference \[8.3\] | Elastic](https://www.elastic.co/guide/en/beats/metricbeat/8.3/metricbeat-modules.html)**
