log4j1。x Sentry appender：为一个appender抑制来自特定来源的警告

Question

我用的是log4j1。x appender用于Sentry跟踪错误记录。

我想忽略来自某些来源的警告，例如来自记录器dre的警告。mytest。我可以用log4j来做这个吗。属性文件？现在看起来是这样的。

# Root logger option
log4j.rootLogger=INFO, stdout, Sentry

# Configure the Sentry appender, overriding the logging threshold to the WARN level
log4j.appender.Sentry=com.getsentry.raven.log4j.SentryAppender
log4j.appender.Sentry.threshold=WARN
log4j.appender.Sentry.tags=system:annotator

我试过了

log4j.logger.dre.mytest=INFO, stdout
log4j.logger.dre.mytest=ERROR, Sentry

但这不会将任何低于错误的内容记录到标准输出。

Answer 1

使用另一个appender解决了此问题：

# Root logger option
log4j.rootLogger=INFO, stdout, SentryWarn

# Direct log messages to stdout
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n

# Configure Sentry appenders, each with their own threshold
log4j.appender.SentryInfo=com.getsentry.raven.log4j.SentryAppender
log4j.appender.SentryInfo.threshold=INFO
log4j.appender.SentryInfo.tags=system:app

log4j.appender.SentryWarn=com.getsentry.raven.log4j.SentryAppender
log4j.appender.SentryWarn.threshold=WARN
log4j.appender.SentryWarn.tags=system:app

log4j.appender.SentryError=com.getsentry.raven.log4j.SentryAppender
log4j.appender.SentryError.threshold=ERROR
log4j.appender.SentryError.tags=system:app

# To suppress warnings from loggers to Sentry, use the following
# log4j.logger.<your-logger-here>=INFO, stdout, SentryError
# log4j.additivity.<your-logger-here> = false

# To send info and higher to Sentry, use the following
# log4j.logger.dre.mytest=INFO, stdout, SentryInfo
# log4j.additivity.dre.mytest = false

升级到Log4j 2后，它看起来像这样：

<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="WARN"
               packages="org.apache.logging.log4j.core,com.getsentry.raven.log4j2">

        <Console name="Console" target="SYSTEM_OUT">
            <PatternLayout pattern="%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n"/>
        </Console>
        <Raven name="Sentry">
            <tags>system:app</tags>
        </Raven>
    </Appenders>

            <AppenderRef ref="Console"/>
            <AppenderRef ref="Sentry" level="warn"/>
        </Root>
        <Logger name="dre.test"
                level="INFO"
                additivity="false">
            <AppenderRef ref="Console"/>
            <AppenderRef ref="Sentry" level="error"/>
        </Logger>
    </Loggers>
</Configuration>
