[syslog-ng] Verifying local logs and remote logs are being sent to destination graylog

[Rodney Bizzell]

I want to make sure that my local logs on my syslog box are being sent to
my graylog host what config changes do I need to make to ensure that is
configured correctly. Can I have an example for illustration. Thanks.

@version:3.5
@include "scl.conf"

# syslog-ng configuration file.
#
# This should behave pretty much like the original syslog on RedHat. But
# it could be configured a lot smarter.
#
# See syslog-ng(8) and syslog-ng.conf(5) for more information.
#
# Note: it also sources additional configuration files (*.conf)
#       located in /etc/syslog-ng/conf.d/
