common.logging是基于java语言的一个日志门面框架,是Apache基金会下的commons项目下的一个子项目,让你的日志脱离具体的实现。
Commong.Logging是.NET下的日志门面框架,它是基于C#语言的移植。并且做了一些基于Windows的扩展。比如ETW(Windows事件跟踪)等独特的日志记录和收集方式。关于如何收集ETW可以参考https://www.cnblogs.com/artech/p/logging-via-etw.html 。
今天主要讲讲MultipleLogger的配置,首先我们使用nuget安装相关的软件包,最开始的时候我是自己尝试,一直没有配置正确,后来在源码的tests目录下,找到了单元测试的配置文件才搞明白。
App.config见下:
<?xml version="1.0" encoding="utf-8" ?> <configuration> <configSections> <sectionGroup name="common"> <section name="logging" type="Common.Logging.ConfigurationSectionHandler, Common.Logging"/> <section name="logging.multipleLoggers" type="Common.Logging.MultipleLogger.ConfigurationSectionHandler, Common.Logging.MultipleLogger"/> </sectionGroup> <section name="nlog" type="NLog.Config.ConfigSectionHandler, NLog" /> <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/> </configSections> <common> <logging> <factoryAdapter type="Common.Logging.MultipleLogger.MultiLoggerFactoryAdapter, Common.Logging.MultipleLogger"> <arg key="MeaninglessKey" value="MeaninglessValue"/> </factoryAdapter> </logging> <logging.multipleLoggers> <factoryAdapter type="Common.Logging.Log4Net.Log4NetLoggerFactoryAdapter, Common.Logging.Log4Net1215"> <!--FILE FILE-WATCH INLINE EXTERNAL--> <!-- --> <!--<arg key="configType" value="INLINE" />--> <arg key="configType" value="FILE-WATCH" /> <arg key="configFile" value="~/log4net.config" /> <!--log4net使用独立的配置文件--> </factoryAdapter> <factoryAdapter type="Common.Logging.NLog.NLogLoggerFactoryAdapter, Common.Logging.NLog4412"> <arg key="configType" value="FILE" /> <arg key="configFile" value="~/NLog.config" /> </factoryAdapter> <factoryAdapter type="Common.Logging.ETW.ETWLoggerFactoryAdapter,Common.Logging.ETWLogger"> <arg key="level" value="DEBUG"/> <!--<arg key="commonLoggingEventSourceType" value="Common.Logging.ETW.CommonLoggingEventSource,Common.Logging.ETWLogger"/>--> <arg key="permitDuplicateEventSourceRegistration" value="false"/> </factoryAdapter> </logging.multipleLoggers> </common> <startup> <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5.2" /> </startup> </configuration>
在配置Section时,除了标准的loggin外,记得把Multe的处理节点也要配置上,如下:
<section name="logging.multipleLoggers" type="Common.Logging.MultipleLogger.ConfigurationSectionHandler, Common.Logging.MultipleLogger"/>
记住,这两个一个都不要少。
然后配置一个log4net.config配置文件:
<?xml version="1.0" encoding="utf-8" ?> <log4net> <!--<appender name="ConsoleAppender" type="log4net.Appender.ConsoleAppender"> <layout type="log4net.Layout.PatternLayout"> <conversionPattern value="%date [%thread] %-5level %logger %ndc - %message%newline" /> </layout> </appender>--> <appender name="InfoRollingLogFileAppender" type="log4net.Appender.RollingFileAppender, log4net"> <param name="LockingModel" type="log4net.Appender.FileAppender+MinimalLock" /> <param name="File" value="logs/" /> <param name="StaticLogFileName" value="false" /> <param name="DatePattern" value="'Info-'yyyy-MM-dd.'log'" /> <param name="AppendToFile" value="true" /> <param name="MaxSizeRollBackups" value="10" /> <param name="MaximumFileSize" value="5MB" /> <param name="RollingStyle" value="Date" /> <!--Size ==- Date--> <layout type="log4net.Layout.PatternLayout"> <param name="ConversionPattern" value="%d [%t] %-5p %c - %m%n" /> </layout> <filter type="log4net.Filter.LevelRangeFilter"> <levelMin value="DEBUG"/> <levelMax value="WARN"/> </filter> </appender> <appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender, log4net"> <param name="LockingModel" type="log4net.Appender.FileAppender+MinimalLock" /> <param name="File" value="logs/" /> <param name="StaticLogFileName" value="false" /> <param name="DatePattern" value="'Error-'yyyy-MM-dd.'log'" /> <param name="AppendToFile" value="true" /> <param name="MaxSizeRollBackups" value="10" /> <param name="MaximumFileSize" value="5MB" /> <param name="RollingStyle" value="Date" /> <!--Size ==- Date--> <layout type="log4net.Layout.PatternLayout"> <param name="ConversionPattern" value="%d [%t] %-5p %c - %m%n" /> </layout> <filter type="log4net.Filter.LevelRangeFilter"> <levelMin value="ERROR"/> <levelMax value="FATAL"/> </filter> </appender> <appender name="DefaultRollingLogFileAppender" type="log4net.Appender.RollingFileAppender, log4net"> <param name="LockingModel" type="log4net.Appender.FileAppender+MinimalLock" /> <param name="File" value="logs/" /><!--文件保存的路径--> <param name="StaticLogFileName" value="false" /><!--文件名动态生成--> <param name="DatePattern" value="'Default-'yyyy-MM-dd.'log'" /><!--文件名命名规则--> <param name="AppendToFile" value="true" /> <param name="MaxSizeRollBackups" value="10" /> <param name="MaximumFileSize" value="5MB" /><!--文件超过5M将创建新文件--> <param name="RollingStyle" value="Date" /> <!--Size ==- Date--> <layout type="log4net.Layout.PatternLayout"> <param name="ConversionPattern" value="%d [%t] %-5p %c - %m%n" /><!--日志内容格式--> </layout> <filter type="log4net.Filter.LevelRangeFilter"><!--日志级别过滤器:此附加器只附加指定级别的日志--> <levelMin value="DEBUG"/> <levelMax value="FATAL"/> </filter> </appender> <root> <level value="ALL" /> <appender-ref ref="RollingLogFileAppender" /> <appender-ref ref="InfoRollingLogFileAppender" /> </root> <logger name="MyApp.DataAccessLayer"> <level value="DEBUG" /> </logger> <!-- ALL DEBUG INFO WARN ERROR FATAL OFF [DEBUG < INFO < WARN < ERROR < FATAL] 大范围 到 小范围--> <logger name="LogDemoWeb._Default" debug="false"> <level value="ALL" /> <appender-ref ref="DefaultRollingLogFileAppender" /> </logger> </log4net>
再来一个NLog的配置文件NLog.config:
<?xml version="1.0" encoding="utf-8" ?> <nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.nlog-project.org/schemas/NLog.xsd NLog.xsd" autoReload="true" throwExceptions="false" internalLogLevel="Off" internalLogFile="c:\temp\nlog-internal.log"> <variable name="variable1" value="${newline}date: ${date}${newline}level: ${level}${newline}logger: ${logger}${newline}machinename: ${machinename} ${newline}message: ${message}${newline}appdomain: ${appdomain}${newline}assembly-version: ${assembly-version}${newline}basedir: ${basedir} ${newline}callsite: ${callsite}${newline}callsite-linenumber: ${callsite-linenumber}${newline}counter: ${counter}${newline}nlogdir: ${nlogdir} ${newline}processid: ${processid}${newline}processname: ${processname}${newline}specialfolder: ${specialfolder} ${newline}stacktrace: ${stacktrace}${newline}-----------------------------------------------------------" /> <targets> <target name="log_file" xsi:type="File" fileName="${basedir}/LogInformation/${level}_${shortdate}.txt" layout="${variable1}" /> </targets> <rules> <logger name="*" writeTo="log_file" /> </rules> </nlog>
虽然这个多日志输出的Adapter作用不大,但我们也不得不佩服这些开源人的想法。
