How to use logback configuration (as the standard application log) in Sentinel logging?

[goudai]

你好，请问我该如何配置让sentinel中的日志变成标准的应用日志（跟随我的logback配置），而不是输出到奇怪位置的文件。

Currently, Sentinel does not support delegating logs to other logging libraries (e.g. slf4j). You may configure the log directory via the csp.sentinel.log.dir property item.

Sentinel 的日志分好几个 Metrics log record log 还有block log 前两个需要自己配置
`

<appender name="sentinel_record" class="ch.qos.logback.core.rolling.RollingFileAppender">
    <file>${catalina.base}/logs/sentinel-record.log</file>
    <append>true</append>
    <encoder>
        <pattern>${sentinel-pattern}</pattern>
        <charset>${encoding}</charset>
    </encoder>
    <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
        <fileNamePattern>${catalina.base}/logs/sentinel-record.%d{yyyy-MM-dd-HH}.log</fileNamePattern>
    </rollingPolicy>
</appender>
<appender name ="async_sentinel_record" class= "ch.qos.logback.classic.AsyncAppender">
    <discardingThreshold >0</discardingThreshold>
    <queueSize>512</queueSize>
    <neverBlock>true</neverBlock>
    <appender-ref ref ="sentinel_record"/>
</appender>

<!--sentinel_metric日志输出-->
<appender name="sentinel_metric" class="ch.qos.logback.core.rolling.RollingFileAppender">
    <file>${catalina.base}/logs/sentinel-metric.log</file>
    <append>true</append>
    <encoder>
        <pattern>${sentinel-pattern}</pattern>
        <charset>${encoding}</charset>
    </encoder>
    <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
        <fileNamePattern>${catalina.base}/logs/sentinel-metric.%d{yyyy-MM-dd-HH}.log</fileNamePattern>
    </rollingPolicy>
</appender>
<appender name ="async_sentinel_metric" class= "ch.qos.logback.classic.AsyncAppender">
    <discardingThreshold >0</discardingThreshold>
    <queueSize>512</queueSize>
    <neverBlock>true</neverBlock>
    <appender-ref ref ="sentinel_metric"/>
</appender>

另外设置 VM OPTIONS -Dcsp.sentinel.log.dir={YOUR LOG DIR}
