Hi All,

I am trying to output logs from Graylog to Logstash.

I have configured the Output settings (GELF) for Graylog from GUI as below -  
 ![image](https://us1.discourse-cdn.com/flex016/uploads/graylog/original/2X/3/3f5144453c2bb5c17e2da657024c08bc2aaf1f1f.png)

my logstash.pem file has cert and key both added.

On the logstash side I have configured the input file with the cert and key.

I am not able to see logs on the logstash when I configure the TCP+TLS output from Graylog. Do I need to make any more configs on the Graylog ? is any modification needed in graylog.conf ?

Please advice.

Thanks.

Do you have a stream tied to that output? Also, I would suggest you get it working without TLS and then lock it down. Too many variables if you start with TLS.
