Hi,
When using an external ruby script parameters can be used with
path =\> "script.rb"
script\_params =\> {
"url\_host\_port" =\> "[http://localhost:9200](http://localhost:9200)"
"url\_username" =\> "{es\_user}" "url\_password" =\> "{es\_password}"
}
How can I do the same with an 'inline' script?
Can I just use {es\_user} and {es\_password} in the script directly?
Regards Hans

Use the [event API](https://www.elastic.co/guide/en/logstash/current/event-api.html).

It is still not clear to me.
Can I just reference : event.get("es\_user" ) then if es\_user is defined in the keystore of logstash?
Or via @metadata
The documentation is very concise.

If [es\_user] is a field on the event then in script.rb you can fetch its value using event.get("es\_user")

Sorry there is a misunderstanding.
I want to use logstash keystore values in the inline script.
Just as my example in my first post.
Parameters can be passed to a ruby script (external).
How can I do it with an inline ruby script?

Sorry, I missed that you were referring to the keystore. If the keystore substitutions are done by event.sprintf() then you could try using that. I'm not in a position to test that tonight.
