NLOG不会在服务器上记录未处理的异常

时间：2018-09-20 17:56:49

标签： nlog

我遇到以下行为：

  1. 在开发中（本地），记录异常没有问题，所有类型的工程都可以。

  2. 当我登录远程服务器（通过远程桌面连接）并在服务器内部打开镶边并创建异常时，也没有问题，所有日志记录都可以工作。

  3. 如果我使用笔记本电脑和Chrome浏览器打开服务器上托管的同一网站：

控制器/操作

{
   // log record gets created for the following line
   logger.Log(LogLevel.Fatal, "Sample informational message"); 

   // log record not created. However this record get created in item 1 and 2 case above
   int a = int.Parse("A");  
}

Global.asax 

 protected void Application_Error(object sender, EventArgs e)
 {
        Logger logger = LogManager.GetCurrentClassLogger();
        logger.Fatal(Server.GetLastError());
        Server.ClearError();
 }

NLog.config

MVC 5项目。 .Net 4.5.2。 NLog版本4.5.7

我还在项目中使用SignalR。日志文件夹具有IIS_IUSRS的修改权限。

就我而言，事实证明Application_Error在服务器环境中没有被调用。实施OnException方法并登录该方法解决了该问题。
