记录到一个单独的日志文件，为每个线程 [英] Logging to an individual log file for each individual thread

问题描述

我有一个服务的应用程序，在启动时读取XML文件，并启动一个线程为XML文件中的每个条目。每个线程创建一个工人类这需要一个记录器，以任何输出记录到一个线程特定日志文件的一个实例。

I have a service application that on startup reads an XML file and starts a thread for each entry in the XML file. Each thread creates an instance of a worker class which requires a logger to log any output to a thread specific log file.

在我的app.config已设置使用XML的appender log4net的配置设置和文件被指定为PatternString如下服务：

In the services app.config I have the log4net configuration settings set to use an XML appender and the file is specified as a PatternString as shown below:

<appender name="XmlAppender" type="log4net.Appender.FileAppender">
  <file type="log4net.Util.PatternString" value="D:\Temp\Logs\%property{LogName}.log" />
  <immediateFlush value="true"/>
  <appendToFile value="true" />
  <layout type="log4net.Layout.SimpleLayout" />
</appender>

在所创建我得到使用 log4net.LogManager.GetLogger（MyLogger）方法，然后我把记录器工人阶级的每个实例线程锁定的方法当前线程使用PatternStrings LOGNAME属性 ThreadContext.Properties [LOGNAME] =日志名称preFIX。

In a thread locked method for each instance of the worker class created I get the logger using the log4net.LogManager.GetLogger("MyLogger") method and then I set the current threads PatternStrings LogName property using ThreadContext.Properties["LogName"] = "Log name prefix".

所有的文件被创建，但在记录器被称为它只是记录所有发送给一个看似随机的文件。

All of the files are created but when the logger is called it just logs all message to one seemingly random file.

我已搜查约了好一阵子试图找到一个解决办法，或一些答案什么我做错了，但我有没有运气。

I have searched about for quite a while trying to find a solution or some answers to what I am doing wrong but I have had no luck.

有没有人有任何想法，为什么发生这种情况？

Does anyone have any idea why this is happening?

推荐答案

我想我已经摸索出了问题。该步骤如下：

I think I have worked out the issue. The steps follow:

• 创建一个名为LoggerRepository每个线程上的个人。


• 将ThreadContexts属性的日志文件名。


• 使用XmlConfiguratior配置资源库。


• 使用日志管理使用命名LoggerRepository该线程获取指定的记录器（XML配置文件中）。

在回报，我得到一个新的配置记录指向该线程相应的文件。

In return I get a new configured logger pointing to the respective file for that thread.

XML配置是相同的，因为它是最初和这里示出为了完整性：

The XML configuration is the same as it was originally and shown here for completeness:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <configSections>    
    <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/>
  </configSections>
  <log4net>
    <logger name="ProductionLogger">
      <appender-ref ref="XmlAppender"/>      
      <level value="ALL"/>
    </logger>
    <appender name="XmlAppender" type="log4net.Appender.FileAppender">
      <file type="log4net.Util.PatternString" value="D:\Temp\Logs\%property{LogName}.log" />
      <immediateFlush value="true"/>
      <appendToFile value="true" />
      <layout type="log4net.Layout.SimpleLayout" />
    </appender>
  </log4net>
</configuration>

在code创建伐木者如下。每次这个code运行它在自己的线程中运行。

The code to create the loggers is below. Each time this code is run it is run in its own thread.

ILoggerRepository loggerRepository = LogManager.CreateRepository(logFileName + "Repository");
ThreadContext.Properties["LogName"] = logFileName;
log4net.Config.XmlConfigurator.Configure(loggerRepository);
ILog logger = LogManager.GetLogger(logFileName + "Repository", "ProductionLogger");

这似乎到目前为止，没有问题需要解决。我期待这个解决方案的时刻进行移动，但是如果我发现了什么事我会更新这个帖子。

This seems to work with no issues so far. I will be moving forward with this solution for the moment but I will update this post if I find out anything else.
