The latest source has support for this: /* # syslog_full #------------------------------- # Available as both a log and alert output plugin. Used to output data via TCP/UDP or LOCAL ie(syslog()) # Arguments: # sensor_name $sensor_name - unique sensor name # server $server - server the device will report to # local - if defined, ignore all remote information and use syslog() to send message. # protocol $protocol - protocol device will report over (tcp/udp) # port $port - destination port device will report to (default: 514) # delimiters $delimiters - define a character that will delimit message sections ex: "|", will use | as message section delimiters. (default: |) # separators $separators - define field separator included in each message ex: " " , will use space as field separator. (default: [:space:]) # operation_mode $operaion_mode - default | complete : default mode is compatible with default snort syslog message, complete prints more information such as the raw packet (hexed) # log_priority $log_priority - used by local option for syslog priority call. (man syslog(3) for supported options) (default: LOG_INFO) # log_facility $log_facility - used by local option for syslog facility call. (man syslog(3) for supported options) (default: LOG_USER) # payload_encoding - (default: hex) support hex/ascii/base64 for log_syslog_full using operation_mode complete only. # Usage Examples: # output alert_syslog_full: sensor_name snortIds1-eth2, server xxx.xxx.xxx.xxx, protocol udp, port 514, operation_mode default # output alert_syslog_full: sensor_name snortIds1-eth2, server xxx.xxx.xxx.xxx, protocol udp, port 514, operation_mode complete # output log_syslog_full: sensor_name snortIds1-eth2, server xxx.xxx.xxx.xxx, protocol udp, port 514, operation_mode default # output log_syslog_full: sensor_name snortIds1-eth2, server xxx.xxx.xxx.xxx, protocol udp, port 514, operation_mode complete # output alert_syslog_full: sensor_name snortIds1-eth2, server xxx.xxx.xxx.xxx, protocol udp, port 514 # output log_syslog_full: sensor_name snortIds1-eth2, server xxx.xxx.xxx.xxx, protocol udp, port 514 # output alert_syslog_full: sensor_name snortIds1-eth2, local # output log_syslog_full: sensor_name snortIds1-eth2, local, log_priority LOG_CRIT,log_facility LOG_CRON --- Michael Shirk On Wed, Oct 1, 2014 at 2:26 PM, Joel Esler (jesler) <jesler () cisco com> wrote:

I’m trying to send it to LOCAL3 so that I can parse off the logs into its own file in rsylog.conf. No matter what I try, I will only get ‘fast’ alert data in /var/log/messages on my rsyslog server (not the local3.* entry as expected). The "operation_mode complete” switch is supposed to set the alerts to full logging, but it doesn’t work remote or locally.
