log4j2 syslog 附加程序在 springboot 中不起作用

Question

我正在尝试使用 log4j2 syslog 附加程序将消息从我的 springboot 应用程序写入 syslog。

这是我的log4j2.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE XML>
<Configuration name="XMLConfig">
<Properties>
    <Property name="LOG_PATTERN">%d %p %C{1.} [%t] %m%n</Property>
</Properties>
<Appenders>
    <Console name="Console" target="SYSTEM_OUT">
        <PatternLayout pattern="%highlight{%d{HH:mm:ss.SSS} %-5level %logger{36}.%M() @%L - %msg%n%throwable}{FATAL=red blink, ERROR=red, WARN=yellow bold, INFO=black, DEBUG=green bold, TRACE=blue}" />

    </Console >

    <RollingFile name="RollingFile"
                 fileName="/data/storage/log/app.log"
                 filePattern="/data/storage/log/app.%d{yyyy-MM-dd}.%i.Logs.gz">
        <PatternLayout pattern="${LOG_PATTERN}" />
        <Policies>
            <SizeBasedTriggeringPolicy size="100 MB" />
            <TimeBasedTriggeringPolicy />
        </Policies>
        <DefaultRolloverStrategy max ="100">
            <Delete basePath="/data/storage/log/" maxDepth="2">
                <IfFileName glob="*/app*.Logs.gz" />
                <IfLastModified age="P7D" />
            </Delete>
        </DefaultRolloverStrategy>
    </RollingFile>
    <Syslog name="Syslog" format="RFC5424" host="127.0.0.1" port="514"
            protocol="UDP" appName="myApp" enterpriseNumber="25979" facility="LOCAL0" />
</Appenders>

<Loggers>

    <Root level="error">
        <AppenderRef ref="RollingFile" />
        <AppenderRef ref="Console" />
    </Root>
    <Logger name="com.manjosh" level ="error" additivity="false">
        <AppenderRef ref="RollingFile" />
        <AppenderRef ref="Console" />
    </Logger>
    <Logger name="com.manjosh.cms.vnf.util.SyslogUtil" level ="debug" additivity="false">
        <AppenderRef ref="Syslog"/>
    </Logger>
</Loggers>

我也在我的服务器上启用了 rsyslog

[root@cmsnfv-c_7_1_53_0_standby_karthik ~]# sudo netstat -tulnp | grep 514
udp        0      0 127.0.0.1:514           0.0.0.0:*                           2785/rsyslogd 

我还看到 log4j 已正确初始化

2024-09-25 09:05:54,098 main DEBUG Registering MBean org.apache.logging.log4j2:type=33c7353a

2024-09-25 09:05:54,279 main DEBUG AsyncLogger.ThreadNameStrategy=CACHED

但是，我仍然没有看到任何写入 /var/log/syslog 或 localO.log 的消息或消息 我看到控制台和文件附加器工作正常。

我使用的是springboot 1.5.4 我正在使用

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-log4j2</artifactId>
    </dependency>

你可以尝试跑步吗

sudo 服务 rsyslog 状态

确保没有错误。如果有任何错误，请重新启动服务。 希望 rsyslog 不会因为任何空间或内存问题而崩溃。
