Estou tentado fazer a configuração do SYSLOG-NG para centralizar os logs do meu servidor. Até Consegui configurar para que os logs fossem enviados para meu centralizador de logs, e eles chegam, porem estão indo todos para /var/log/messages.
Gostaria de saber se é possível configurá-lo para que os logs sejam separados por hosts. Segue abaixo meu syslog-ng.conf:

Desde já agradeço a ajuda


#
# Configuration file for syslog-ng under Debian
#
# attempts at reproducing default syslog behavior
# the standard syslog levels are (in descending order of priority):
# emerg alert crit err warning notice info debug
# the aliases "error", "panic", and "warn" are deprecated
# the "none" priority found in the original syslogd configuration is
# only used in internal messages created by syslogd

# the number of lines buffered before written to file
# you might want to increase this if your disk isn't catching with
