Elmah.MVC不会在生产环境中记录错误

问题描述

我使用将Elmah.MVC安装到我的MVC项目中。它在开发环境中可以正常工作，但是当我将网站上传到托管服务器（IIS7）时，它不会记录错误。

I installed Elmah.MVC to my MVC project using Elmah.MVC Nuget package. It works fine in development environment, but when I upload website to hosting server (IIS7) it does not log errors.

这是我的Web配置文件（仅Elmah配置），

This is my web config file (only the Elmah configuraion),

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <configSections>
        ...

有人可以检查&告诉它为什么在托管环境中不记录错误？

Can someone please check & tell why it is not logging errors in Hosting environment?

推荐答案

您的应用程序是否对生产环境中的App_Data目录具有写权限？

Does your application have write access to the App_Data directory in your production environment?

根据您的配置，您没有登录到SQL->应用程序池标识将需要能够修改/写入文件才能追加到App_Data /Elmah.Errors文件。

Based on your configuration, you are not logging to SQL -> the application pool identity will need to be able to modify/write to files in order to append to the App_Data/Elmah.Errors file. More information on the why and how.
