DataDog无代理模式无法接收日志问题求助

使用DataDog无代理模式时，日志无法被正常接收。已严格遵循官方教程完成配置，但日志始终未按预期直接发送至DataDog服务器，请求协助排查解决。以下是相关配置信息：

Spring Boot的logback-spring.xml配置 #

<configuration>

    <appender name="syslog" class="net.logstash.logback.appender.LogstashTcpSocketAppender">

                </layout>

    </appender>
    <root level="trace">
        <appender-ref ref="console" />
        <appender-ref ref="syslog" />
    </root>

</configuration>
