Hey guys.
One of my inputs is for syslog and currently only a single fpsense box sends its firewall logs to it. I can easily pass this into its own stream. However, Graylog is not recording a hostname. I tried the rDNS setting on the input stream but no success. I have more syslog sources that need to send their logs so I am looking for a way to set the hostname on those messages.
I figured I’d make a reverse lookup table, data adapter and cache. They work fine, I can query and get results. The cache shows hits too.
I’ve made a stream based on the internal field, gl2_remote_ip. If I want to make a decorator, choose lookup table, I don’t get to choose the lookup table I created earlier.
I found one other problem but it has no solution:
Has anyone an idea what might be going on?
Thanks!
Ps. Logs show all is good too:
