Hi,

I've successfully managed to ship JSON structured logs to Kibana 4.5.1 with Filebeat 5.0.0-alpha2.

I've created second prospector in my filebeat.yml to parse simple traditional log lines stored in others log files. But I can't understand where should I set a regexp pattern to tell Filebeat how to parse these traditional log lines.

Does someone know how to do this, please?

Thanks,  
Chris

Filebeat doesn't parse logs. You'll typically want to use Logstash for that.

That's alright, thank you Magnus.
