This is pretty much the same as described here.
I’ve followed these instructions but eventually, no messages.
I’ve tried to check any possible log but I can’t find any issue there.
Basically, I’ve installed the sidecar-collector on one remote host (working against a previous Centos6 graylog server), configured the beat input and collectors (both input and output) on graylog srv. When I check “All messages” stream, nothing is shown even if all the collectors looks healthy (green).
I’ve tried to disable selinux as well, rebooted, nothing.
I’m trying to move from a working CentOS6 server to CentOS7, the configuration is copied from the previous which is currently showing messages as expected.
Any idea on what could be wrong on this server?
