Hi,

I am looking to use the user\_agent filter in logstash. In the guide ([https://www.elastic.co/guide/en/logstash/current/plugins-filters-useragent.html#plugins-filters-useragent-regexes](https://www.elastic.co/guide/en/logstash/current/plugins-filters-useragent.html#plugins-filters-useragent-regexes)) it states  
If not specified, this will default to the `regexes.yaml` that ships with logstash

Where would this file be within logstash? I have searched and cannot find it, i am trying to find out if that is kept upto date by logstash. I am on 7.10

Thanks

@Badger  
Thank you, didnt think to look in the files. I will be pulling the latest regexes myself then for the user agent.
