Nginx: Running latest nginx on Ubuntu. We have added some custom fields to the access log (e.g. server_name).
Filebeat: Just setup 7.4.1 and trying to use the filebeat nginx module to send the log files to our version 7.4.1 ELK. I have it all setup and it is working - kibana dashboard and all. However I do not know how to include the custom log fields?
How can I tweak the filebeat.yml to include the custom log field "server_name" above?
