How to use ruby script file with parameter?

Elastic Stack Logstash
1

Hi,

sometimes I used ruby as logstash filter plugin - only the inline functionality until now. Additionally I have to admit, that I am not really fond of ruby.

Now I wanna outsource the code to a script file, but I do not understand the explanation at https://www.elastic.co/guide/en/logstash/current/plugins-filters-ruby.html

I would like to do the following:

  • create a field which has the current timestamp as value and store it in the event
  • set a part of the name as variable (variable name)

Following ruby code snipped should work:

myTime=timeStart=DateTime.now.strftime("%Q").to_i    
event.set("[logstash][debug][" + name + "]",myTime )

But I do not understand how to outsource this to a file and how to give the name as parameter.

Can anyone provide an example on this simple issue?

Thanks, Andreas

From where would name come in your inline Ruby snippet?

its not done yet.

I am looking for a way to set this as parameter / argument when I call the script file inside the logstash filter clause.

Did you look at the script_params option described in the documentation?

yes, but unfortunately I did not understand it. Maybe too few ruby knowledge...
