Im sending logs data via filebeat to my graylog2 server and I want to rewrite this message here:
ERROR [2018-05-20 11:35:28,204] [pool-tread-3] Filter - [Number-155], [PUT] [http://localhost/Item] ==>> {“Item”:{“file”:“base64string”,"}}
I want to remove this base64string from the message before forwarding it to graylog2.
Is this possible and how? If someone has some examples it would be nice.
Thanks
