[syslog-ng] Host/port from environment variables

[Peter Flood]

Hi

I'm trying configure syslog-ng, I'd like to be able to use environment 
variables for host & port. I've tried the ones that work in the template 
formatter but it's not working (not suprisingly). Is there another way?

destination d_my_dest {
     tcp("$(env MY_HOST)" port($(env MY_PORT))  # this doesn't work as 
you can't get env vars unless in a template
     tls(peer-verify(required-untrusted) ca_dir("/etc/syslog-ng/cert.d"))
     template(myTemplate));
};

Thanks
