 +
 +#### MODULES ####
 +
 +# The imjournal module bellow is now used as a message source instead of imuxsock.
 +$ModLoad imuxsock # provides support for local system logging (e.g. via logger command)
 +$ModLoad imjournal # provides access to the systemd journal
 +#$ModLoad imklog # reads kernel messages (the same are read from journald)
 +#$ModLoad immark  # provides --MARK-- message capability
 +
 +# Provides UDP syslog reception
 +#$ModLoad imudp
 +#$UDPServerRun 514
 +
 +# Provides TCP syslog reception
 +#$ModLoad imtcp
 +#$InputTCPServerRun 514
 +
 +
 +#### GLOBAL DIRECTIVES ####
 +
 +# Where to place auxiliary files
 +$WorkDirectory /var/lib/rsyslog
 +
 +# Use default timestamp format
 +$ActionFileDefaultTemplate RSYSLOG_TraditionalFileFormat
 +
 +# File syncing capability is disabled by default. This feature is usually not required,
 +# not useful and an extreme performance hit
 +#$ActionFileEnableSync on
 +
 +# Include all config files in /etc/rsyslog.d/
 +$IncludeConfig /etc/rsyslog.d/*.conf
 +
 +# Turn off message reception via local log socket;
 +# local messages are retrieved through imjournal now.
 +$OmitLocalLogging on
 +
 +# File to store the position in the journal
 +$IMJournalStateFile imjournal.state
 +
 +
 +#### RULES ####
 +
 +# Log all kernel messages to the console.
 +# Logging much else clutters up the screen.
 +#kern.*                                                 /dev/console
 +
 +# Log anything (except mail) of level info or higher.
 +# Don't log private authentication messages!
 +*.info;mail.none;authpriv.none;cron.none                /var/log/messages
 +
 +# The authpriv file has restricted access.
 +authpriv.*                                              /var/log/secure
 +
 +# Log all the mail messages in one place.
 +mail.*                                                  -/var/log/maillog
 +
 +# Added By Michael

 +
 +# Save news errors of level crit and higher in a special file.

 +# ### begin forwarding rule ###
 +# The statement between the begin ... end define a SINGLE forwarding
 +# rule. They belong together, do NOT split them. If you create multiple
 +# forwarding rules, duplicate the whole block!
 +# Remote Logging (we use TCP for reliable delivery)
 +#
 +# An on-disk queue is created for this action. If the remote host is
 +# down, messages are spooled to disk and sent when it is up again.
 +#$ActionQueueFileName fwdRule1 # unique name prefix for spool files
 +#$ActionQueueMaxDiskSpace 1g   # 1gb space limit (use as much as possible)
 +#$ActionQueueSaveOnShutdown on # save messages to disk on shutdown
 +#$ActionQueueType LinkedList   # run asynchronously
 +#$ActionResumeRetryCount -1    # infinite retries if host is down
 +# remote host is: name/ip:port, e.g. 192.168.0.1:514, port optional
 +#*.* @@remote-host:514
 +# ### end of the forwarding rule ###
