Sentinel Logging Extension SLF4J

To integrate logs of sentinel into your project which uses slf4j for bridge of logging you can simply introduce following dependency to your project:

<dependency>
    <groupId>com.alibaba.csp</groupId>
    <artifactId>sentinel-logging-slf4j</artifactId>
    <version>${sentinel.version}</version>
</dependency>

And if you want to control level of logging special for sentinel the loggers that sentinel uses are called sentinelRecordLogger and sentinelCommandCenterLogger. For example in XML configration coming with log4j2 implementation:

<?xml version="1.0" encoding="UTF-8" ?>
<Configuration>
    <Appenders>
        <Console name="Console" target="SYSTEM_OUT">
            <PatternLayout pattern="%-5level %logger - %msg%n"/>
        </Console>
        <File name="FILE" fileName="sentinel-record.log" append="false">
            <PatternLayout pattern="%-5level %logger - %msg%n"/>
        </File>
        <File name="FILE2" fileName="sentinel-command-center.log" append="false">
            <PatternLayout pattern="%-5level %logger - %msg%n"/>
        </File>
    </Appenders>
    <Loggers>
        <Root level="info"/>
        <logger name="sentinelRecordLogger" level="trace">
            <appender-ref ref="Console" />
            <appender-ref ref="FILE" />
        </logger>
        <logger name="sentinelCommandCenterLogger" level="trace">
            <appender-ref ref="Console" />
            <appender-ref ref="FILE2" />
        </logger>
    </Loggers>
</Configuration>
