Hi,  
is there a way to use a custom regex for nginx user-agent plugin? I tried this with a different pipeline and it works, but when i do this in filebeat json file:  
{  
"user\_agent": {  
"field": "nginx.access.agent",  
"target\_field": "nginx.access.user\_agent",  
"regex\_file": "regexes-custom.yaml"  
}  
it has no effect.

Just to make sure, you are using the Filebeat nginx module, right? Did you edit the `module/nginx/access/ingest/default.json` from the Filebeat distribution?

Note that you might have to delete the old pipeline. In the Kibana Console you can do something like: `DELETE _ingest/pipeline/filebeat-*-nginx*`

well it's a modified one, i copied nginx module from the repository and  
changed it.  
yeah i tried clearing pipelines, and my config is there. Elastic will even  
complain if my regex file isn't there but it's still not using the new  
patterns from the file
