Hey,

When using remote logging (*.* @syslog.example.com) "syslog" is an alias (CNAME with low TTL) in our DNS, like all service names.

Now it seems when we change this alias' destination in DNS, the change is never picked up. Not even on reload, only on restart. On reload would at least make it use the new IP address after logrotation for example.

I don't even think it's about rsyslog. Seems to be how all syslog implementations usually behave. But it is still a topic of discussion:

Are people just not using hostnames? I understand that for example on network equipment you would rather hardcode IPs than use hostnames. But what do you do on the servers?

Is there a best practice with valid reasons why it should be done that way? What do you think?

Cheers.
