 *** `syslog` describes parameters for the `Syslog` logging destination type:
 **** `address` is the IP address of the syslog endpoint that receives log messages.
 **** `port` is the UDP port number of the syslog endpoint that receives log messages.
+**** `maxLength` is the maximum length of the syslog message. It must be between `480` and `4096` bytes. If this field is empty, the maximum length is set to the default value of `1024` bytes.
 **** `facility` specifies the syslog facility of log messages. If this field is empty, the facility is `local1`. Otherwise, it must specify a valid syslog facility: `kern`, `user`, `mail`, `daemon`, `auth`, `syslog`, `lpr`, `news`, `uucp`, `cron`, `auth2`, `ftp`, `ntp`, `audit`, `alert`, `cron2`, `local0`, `local1`, `local2`, `local3`. `local4`, `local5`, `local6`, or `local7`.
 ** `httpLogFormat` specifies the format of the log message for an HTTP request. If this field is empty, log messages use the implementation's default HTTP log format. For HAProxy's default HTTP log format, see link:http://cbonte.github.io/haproxy-dconv/2.0/configuration.html#8.2.3[the HAProxy documentation].
