log4net ForwardingAppender 阈值
我需要配置记录器将消息写入具有不同日志级别的多个附加程序。
对于前。我希望 RefreshDataService
将详细信息记录到 TransportFileAppender
并将警告和错误记录到 RollingFileAppender
。
另外,我使用缓冲来提高日志记录性能。 我设置 FilteredFileLog
附加程序将警告转发到 FileLog->RollingFileAppender。
但对于 RefreshDataService 记录器,所有日志消息(包括调试和信息)都会记录到 FileLog 中。
您能否帮助我配置 RefreshDataService
记录器以仅将 Warn+ 消息记录到 FileLog 中?谢谢。
以下是我的 log4net 配置的摘录。
<appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
<file value="${TEMP}\logs\client\${ENV}\client.log" />
<appendToFile value="true" />
<rollingStyle value="Size" />
<maxSizeRollBackups value="10" />
<maximumFileSize value="4096KB" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %-5level [%property{ENV}] [%property{UID}] %logger - %message%newline" />
</layout>
</appender>
<appender name="TransportAppender" type="log4net.Appender.RollingFileAppender">
<file value="${TEMP}\logs\client\${ENV}\client.comm.log" />
<appendToFile value="true" />
<rollingStyle value="Size" />
<maxSizeRollBackups value="10" />
<maximumFileSize value="4096KB" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %-5level %logger - %message%newline" />
</layout>
</appender>
<appender name="DetailedTransportLog" type="log4net.Appender.BufferingForwardingAppender">
<threshold value="DEBUG" />
<bufferSize value="200" />
<appender-ref ref="TransportAppender" />
</appender>
<appender name="FileLog" type="log4net.Appender.BufferingForwardingAppender">
<bufferSize value="20" />
<lossy value="false" />
<appender-ref ref="RollingFileAppender" />
</appender>
<appender name="FilteredFileLog" type="log4net.Appender.ForwardingAppender">
<threshold value="WARN" />
<appender-ref ref="FileLog" />
</appender>
<logger name="RefreshDataService" >
<level value="DEBUG" />
<appender-ref ref="FilteredFileLog" />
<appender-ref ref="DetailedTransportLog" />
</logger>
I need to configure logger to write messages to several appenders with different Log Levels.
For ex. I want RefreshDataService
to log detailed info to TransportFileAppender
and Warnings and Errors to RollingFileAppender
.
Also, I'm using buffering to improve logging performance.
I setup FilteredFileLog
appender to forward Warnings to FileLog->RollingFileAppender.
But for RefreshDataService logger, all log messages including debug and Info getting logged to FileLog.
Can you help me to configure the RefreshDataService
logger to log only Warn+ messages to FileLog? Thanks.
Below is excerpt from my log4net config.

您可以在附加程序上使用级别范围过滤器:
我的理解是,
Threshold
属性用于告诉附加程序在记录特定级别的消息时刷新缓冲区。通过这种方式,您可以确保错误立即写入数据库。You can use a level range filter on the appender:
My understanding is that the
Threshold
property is used tell the appender to flush the buffer when messages of a certain level are logged. This way you can make for instance sure that errors are written immediately to the database.
