the only thing that rsyslog can change without a restart is to use table_lookup
(with it's ability to reload the table)
everything else, including using environment variables, ould requre a restart
when it changes. Even DNS lookups need to be cached to some extent to avoid
insane numbers of lookups to DNS servers.

Subject: Re: [rsyslog] using backticks with echo or cat for target ip?
Actually, I forward to two seperate machines, and want the ability to stop
forwarding whenever I want. So I thought, that if I put the ip's of the
receivers into files, and want to stop one, I just change the ip in the file
without changing the config file itself.

What are you trying to overcome/achieve.
Perhaps using a hostname rather than IP address would help you.
You could define the hostname and IP in /etc/hosts. This would not require
restarting rsyslog when it changes.
You might otherwise consider using a DynamicDNS server to resolve the
address.

I am trying to have config that does not have the target ip for omfwd
hardcoded (although I probably need to restart the service everytime I
want
it to send to a new ip).
