I have a custom Access log and I want to send it ('output') by Gork pattern. I don't have any access to the Logstash server, and I just can config my Filebeat to send Access log messages in a Grok pattern.
I have a Graylog server and I added a Logstash 'input'. Now I want to send the Acess log to the 'input' with my Grok pattern.
Is there anyway exists that I set my Grok pattern in Filebeat config?
