HI
Tried configuring elasticsearch 5x with syslog.appender using properties format.
appender.syslog.type = syslog
appender.syslog.name = syslog
appender.syslog.format = RFC5424
appender.syslog.exceptionPattern = %throwable{full}
appender.syslog.ignoreExceptions = false
appender.syslog.host =
appender.syslog.port = 514
appender.syslog.protocol = udp
appender.syslog.appName = elasticSearch
appender.syslog.facility = local2
appender.syslog.mdcId = mdc
Throws an exception:
