使用 Logback SSLSocketAppender 时 Splunk 日志显示为十六进制

Question

我正在尝试使用 Splunk 为我的应用程序收集日志。我在端口 6514 上设置了 TCP 数据输入（在此端口上启用了 SSL）。从我的 Java 应用程序，我能够连接到端口并发送日志。但是，当我在 Splunk 网站上查看这些日志时，它显示为十六进制格式。

登录配置

<configuration debug="true">

 <appender name="console" class="ch.qos.logback.core.ConsoleAppender">
    <encoder>
        <pattern>%date{ISO8601} [%thread] [%cyan(%C.%M\(\))] [%highlight(%level)] : %msg - %ex{short} %n</pattern>
    </encoder>
</appender>

<appender name="sslsocket" class="ch.qos.logback.classic.net.SSLSocketAppender">
    <remoteHost>127.0.0.1</remoteHost>
    <port>6514</port>
    <queueSize>20</queueSize>
    <reconnectionDelay>20</reconnectionDelay>
    <ssl>
        <trustStore>
            <location>file:///path/to/truststore.jks</location>
            <password>truststorepassword</password>
        </trustStore>
    </ssl>
</appender>

<logger name="splunk.secure.logger" additivity="false" level="INFO">
    <appender-ref ref="sslsocket"/>
</logger>

<root level="DEBUG">
    <appender-ref ref="console" />
</root>
</configuration>

用法

public class 初学者 {

private final static org.slf4j.Logger logger = LoggerFactory.getLogger("splunk.secure.logger");


public static void main(String[] args) {
    logger.info("Testing SSL Socket Appender Log");
}

}

将调试输出记录回控制台

SPLUNK WEB 接收什么

Time    Event

3/2/19 9:48:45.000 上午
\xAC\xED\x00 host = 127.0.0.1 source = tcp:6514 sourcetype = logback

总结

从上面看来，在我看来这不是连接问题，因为 Splunk 正在侦听端口 6514 并且能够捕获输入但捕获的输入显示为 HEX 而不是正常情况。

当我使用正常 com.splunk.logging.TcpAppender 时，我的日志在 splunk 上正确显示。

是否还有其他我可能遗漏的配置
使用 com.splunk.logging.TcpAppender
是否有专用的 Splunk SSL appender 可以代替 ch.qos.logback.classic.net.SSLSocketAppender
欢迎任何其他建议。

为了解决这个问题，我不得不切换到 log4j。在 log4j 中使用以下配置，日志在 splunk web 上正确显示。

<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="info" name="example" packages="">
<Appenders>
    <Socket name="ssl" host="localhost" port="6514">
        <PatternLayout charset="UTF-8">
            <pattern>%date{ISO8601} [%thread] [%C.%M\(\) - Line %L] [%level] : %msg %ex{short} %n</pattern>
        </PatternLayout>
        <JsonLayout properties="true"/>
        <SSL>
            <TrustStore location="/path/to/keystore.jks" password="password"/>
        </SSL>
    </Socket>
    </Appenders>
    <Loggers>
    <Root level="INFO">
    </Root>
    <Logger name="splunk.secure.logger" level="info">
        <AppenderRef ref="ssl"/>
    </Logger>
    </Loggers>
</Configuration>
