企业库日志记录未从ASP.NET记录到事件日志 [英] Enterprise Library Logging not logging to Event Log from ASP.NET

问题描述

我花了一天的时间尝试使Ent Lib Logging正常工作并将所有内容记录到数据库或事件日志中.我有一个具有相同Ent Lib配置的Web应用程序和控制台应用程序，但是只有控制台应用程序才能登录到事件日志.我尝试了所有具有权限的操作，但我不知道自己在做什么–哪些服务应该具有什么.它不起作用！

I spent a day trying to make Ent Lib Logging work and log anything into database or event log. I have a web application and console application with the same Ent Lib config but only the console application is capable to log into the Event Log. I tried everything with permissions but I don't know what exactly I am doing — which services should have what. It does not work!

我读了这样的文章 http://imar.spaanjaars.com /275/将错误记录到ASPNET应用程序中的事件日志中 并且我想尝试为ASPNET帐户授予这些权限.我正在使用Windows 7，但找不到ASPNET用户帐户.那在哪里呢?

I read articles like this http://imar.spaanjaars.com/275/logging-errors-to-the-event-log-in-aspnet-applications and I want to try to give the ASPNET account those permissions. I am using Windows 7 and I cannot find ASPNET user account. So where is it?

这是从Ent Lib实用程序自动生成的配置文件，它仅适用于App.config，不适用于web.config

This is the config file which is automatically generated from Ent Lib utility and it works only on App.config, not on web.config

推荐答案

我相信在IIS7(我假设您正在使用)下

I believe that under IIS7 (which I am assuming you are using) the application pool will be running under NETWORK SERVICE.

您可以尝试将NETWORK SERVICE完全控制权赋予注册表项HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Eventlog\Application.
(不推荐！)

You could try giving NETWORK SERVICE Full Control to the registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Eventlog\Application.
(Not Recommended!)

或者，您可以将[所有人]的完全控制权授予HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Eventlog\Application，记录一条消息，然后还原该更改.设置密钥后，您将不需要权限即可写入注册表.

Alternatively, you could grant EVERYONE Full control to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Eventlog\Application, log a message, then revert that change. Once the key is set up then you won't need the permissions to write to the registry.

或者您可以手动配置事先需要的注册表项，以避免权限问题:

Or you could manually configure the registry keys that you require beforehand to avoid the permission problems:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Eventlog\Application\Logger]
"EventMessageFile"="c:\\WINNT\\Microsoft.NET\\Framework\\v2.0.50727\\EventLogMessages.dll"

只需根据 MSDN 来更新此答案: 要在Windows Vista和更高版本或Windows Server 2003中创建事件源，必须具有管理特权."

Just an update to this answer that according to MSDN: "To create an event source in Windows Vista and later or Windows Server 2003, you must have administrative privileges".
