I am new to Graylogs and tried installing on Centos 7.0 as per link https://docs.graylog.org/en/3.0/pages/installation/os/centos.html. Mongodb, elastic search and graylogs restarting works fine and I can log into webui. This tells me server is configured properly.
And configured linix listen.conf and rsyslog.conf with the instructions here https://marketplace.graylog.org/addons/a47beb3b-0bd9-4792-a56a-33b27b567856
created a node with below info
- recv_buffer_size: 262144
- store_full_message: false
I couldnt find any info on the ports related such as 514. so not sure if that is causing this. could be port related. can anyone suggest what to look for?
