Using server_name variable in error_log filename

[Ondrej Jombik]

This is good way how to make separate error logging per-server section

http://wiki.nginx.org/SeparateErrorLoggingPerVirtualHost

However we have many shared configuration files in conf.d/ and we have
one especially dedicated to logging.

Is there any variable containing server_name (and port) value which can
be use in filename passed to error_log ?

Thanks

Ondrej
