problem with send log from log4j2 to graylog2 via gelfj

[aminkhodamoradi]

## used dependency and config log4j.xml with

<configuration status="OFF" packages="org.graylog2.log4j2"> <appenders> <Console name="Console" target="SYSTEM_OUT"> <PatternLayout pattern="%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n" /> </Console> <appender name="GrayLog2" class="org.graylog2.log.GelfAppender"> <param name="graylogHost" value="192.168.248.128"/> <param name="graylogPort" value="12201"/> <param name="extractStacktrace" value="true"/> <param name="addExtendedInformation" value="true"/> <param name="facility" value="yourfacility"/> <param name="Threshold" value="WARN"/> <param name="additionalFields" value="{'environment': 'PROD', 'application': yourapplicationname'}"/> </appender> <GELF name="gelfAppender" server="192.168.248.128" port="12201" hostName="appserver01.example.com" additionalFields="foo=bar"/> </appenders> <loggers> <root level="INFO"> <appender-ref ref="GrayLog2"/> <appender-ref ref="gelfAppender"/> <AppenderRef ref="Console" /> </root> </loggers> </configuration>
## now when I run maven project I see this errors and I can't log into graylog2 server.
