Log4net日志记录不适用于并行线程 [英] Log4net logging is not working with parallel threads

问题描述

我在随机数上使用基本的Parallel.Foreach循环，以使用log4net记录数字本身.

I am using basic Parallel.Foreach loop on Random numbers to log number itself using log4net.

这是我的代码，用于在并行线程上记录5000条消息

Here is my code to log 5000 messages on parallel threads

            Logger logger = new Logger();
            var numbers = Enumerable.Range(1, 5000);
            ParallelOptions parallelOptions =
                   new ParallelOptions()
                   {
                       MaxDegreeOfParallelism = Environment.ProcessorCount
                   };
            Parallel.ForEach(numbers, parallelOptions, number =>
            {
                logger.Write(Level.Info, "main method", "" + number + "", loggingParameters);
            });

但是最后在日志文件中只能看到1600条消息.

But in the end only see 1600 messages in the log file.

这是log4net的已知问题吗?还是我在这里做错了什么?

Is this a known issue with log4net ? or am i doing something wrong here ?

我在基于 Answer 的cofig中使用了以下设置，并且该设置仍然相同.

I used the below setting in the cofig based on Answerand its still the same.

<param name="ImmediateFlush" value="true" />

<log4net debug="false">

    <appender name="GeneralRollingFileAppender" type="log4net.Appender.RollingFileAppender">
      <lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
      <file   type="log4net.Util.PatternString" value="Logs/All/all_" />
      <appendToFile value="true" />
      <rollingStyle value="Date" />
      <datePattern value="yyyyMMdd'.log'" />
      <maxSizeRollBackups value="10" />
      <staticLogFileName value="false" />
      <param name="ImmediateFlush" value="true" />
      <filter type="log4net.Filter.LevelRangeFilter">
        <levelMin value="INFO" />
        <levelMax value="INFO" />
      </filter>
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%date [%thread] %-5level %message%newline" />

      </layout>
    </appender>
    <root>
      <appender-ref ref="GeneralRollingFileAppender" />
    </root>
  </log4net>

Log4net版本:1.2.15.0

Log4net version : 1.2.15.0

推荐答案

您正在写GlobalContext，我想您需要写ThreadLogicalContext来使它按您想要的方式工作.

You are writing to the GlobalContext, I guess you need to write to the ThreadLogicalContext instead to get it working the way you want.
