Sample config

log4j.appender.SYSLOG=com.github.loggly.log4j.SyslogAppender64k
log4j.appender.SYSLOG.Facility=LOCAL7
log4j.appender.SYSLOG.FacilityPrinting=false
log4j.appender.SYSLOG.Header=true
log4j.appender.SYSLOG.Rfc5424Format=true
log4j.appender.SYSLOG.SyslogHost={{syslog_server}}:{{syslog_server_port}}
log4j.appender.SYSLOG.Protocol=tcp
log4k.appender.SYSLOG.AppName=MyApp
log4j.appender.SYSLOG.layout=org.apache.log4j.PatternLayout
log4j.appender.SYSLOG.layout.ConversionPattern=%-5p [%t:%C{1}@%L] - %m%n
# https://logging.apache.org/log4j/1.2/apidocs/org/apache/log4j/PatternLayout.html

These properties control the format of the output

log4j.appender.SYSLOG.FacilityPrinting=false
log4j.appender.SYSLOG.Header=true
log4j.appender.SYSLOG.Rfc5424Format=true
log4k.appender.SYSLOG.AppName=MyApp

If log4j.appender.SYSLOG.Rfc5424Format=false, the messages will be output as rfc3164

When using Rfc5424Format, the header fields will be used as

• HOSTNAME: local hostname
• APP-NAME: If not set, will be Main class, determined as

  ManagementFactory.getRuntimeMXBean()
                     .getSystemProperties()
                     .get("sun.java.command")
                     .split(" ", 2)
                     [0]);

• PROCID: The process PID
• MSGID: The timestamp in milliseconds
