Hey there,
I am using the nginx module in filebeat to get the access and error logs into elasticsearch. I've added a custom header (X-Request_Id) to my log output and would like also have that recognized.
I've seen the output.elasticsearch.headers seem to be something I could use, but all the examples I've found are rather static and not something to forward an existing header.
Is it possible to include a custom request header in the elasticsearch output?
Thanks in advance!
