Hi everyone,
im parsing with logstash some message containing an ID refering to an user, i need to add the name of the user with the specific ID. I have all the User and ID in a CSV file.
Which one is the best way to add the name corrisponding to the id in my index?
Thank you in advance

You can use [the translate plugin](https://www.elastic.co/guide/en/logstash/current/plugins-filters-translate.html). Try with this:
```auto
translate {
field => "[userid]"
dictionary_path => "/path/file.csv"
target => "username"
exact => true
}
```
The file.csv need to have the head with userid, username.
_userid, username_
_test, [test@domain.com](mailto:test@domain.com)_
