nlog - NLOG 不在服务器上记录未处理的异常

问题描述

我遇到以下行为：

  1. 在开发（本地）中记录异常没有问题，所有类型的作品。

  2. 当我登录远程服务器（通过远程桌面连接）并在服务器内打开一个 chrome 并创建异常时，也没有问题，所有类型的日志记录都有效。

  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个网站：

控制器/动作

{
   // 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");  
}

全球.asax

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

MVC 5 项目。.Net 4.5.2。NLog 版本 4.5.7

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

解决方案

In my case, It turned out Application_Error do not get called in server environment. implementing OnException method and logging in the method solved the issue.

I post my answer https://github.com/NLog/NLog/issues/2924
