log4net 日志写入MongoDB 实现分布式日志

本人在.net framework 4.5下测试成功，首先需要安装log4mongo-net组件，见https://www.nuget.org/packages/log4mongo-net/

vs2012以上直接使用PM命令 Install-Package log4mongo-net 下载安装

log4net 配置文件log4net.config修改如下：

<?xml version="1.0" encoding="utf-8"?>
<log4net>
<appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
<param name="File" value="log/"/>
<param name="AppendToFile" value="true"/>
<param name="MaxSizeRollBackups" value="10"/>
<param name="StaticLogFileName" value="false"/>
<param name="DatePattern" value="yyyy-MM-dd".log""/>
<param name="RollingStyle" value="Date"/>
<layout type="log4net.Layout.PatternLayout">
<param name="ConversionPattern" value="%d [%t] %-5p %c [%x] - %m%n%n"/>
</layout>
</appender>
<appender name="DUMLogFileAppender" type="log4net.Appender.RollingFileAppender">
<param name="File" value="Dumlog/"/>
<param name="AppendToFile" value="true"/>
<param name="MaxSizeRollBackups" value="10"/>
<param name="StaticLogFileName" value="false"/>
<param name="DatePattern" value="yyyy-MM-dd".log""/>
<param name="RollingStyle" value="Composite"/>
<layout type="log4net.Layout.PatternLayout">
<param name="ConversionPattern" value="%d [%t] %-5p %c [%x] - %m%n%n"/>
</layout>
</appender>
<appender name="MongoDBAppender" type="Log4Mongo.MongoDBAppender, Log4Mongo">
<connectionString value="mongodb://192.168.0.226:6111/?socketTimeout=1s" />
<CollectionName value="Wilson.Log4Net"/>
</appender>

<root>
<level value="ALL" />
<appender-ref ref="RollingLogFileAppender" />
</root>
<logger name="TopeveryByDUM">
<level value="ALL"/>
<appender-ref ref="MongoDBAppender" />
</logger>
</log4net>

AssemblyInfo.cs文件加上如下代码：

[assembly: log4net.Config.XmlConfigurator(ConfigFile = "log4net.config", Watch = true)]

C#源代码：

class Program
{
static void Main(string[] args)
{
log4net.Config.XmlConfigurator.Configure();

log4net.ILog Log = log4net.LogManager.GetLogger("TopeveryByDUM");
for (int i = 0; i < 10000; i++)
{
Console.WriteLine(i);
Log.DebugFormat("Wilson_测试日志内容__{0}", i);
}
}
}

运行结果如下，写入1W条日志耗时2秒左右。
