企业库日志记录未从ASP.NET登录到事件日志

我花了一天时间尝试使Ent Lib Logging工作并将任何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,但只有控制台应用程序能够登录到事件日志。我尝试了所有权限,但我不知道我在做什么 - 哪些服务应该有什么。它不起作用!

我读过这样的文章 http://imar.spaanjaars.com/275/logging-errors-to-the-event-log-in-aspnet-applications 我想尝试给ASPNET帐户这些权限。我使用Windows 7,我找不到ASPNET用户帐户。那它在哪里?

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,而不适用于web.config

4 个答案:

答案 0 :(得分:4)

我相信在IIS7(我假设您正在使用)下application pool will be running under NETWORK SERVICE

您可以尝试向注册表项HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Eventlog\Application提供NETWORK SERVICE完全控制权。
(不推荐!)

或者,您可以将每个人的完全控制权授予HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Eventlog\Application,记录消息,然后还原该更改。设置密钥后,您将不需要具有写入注册表的权限。

或者您可以手动配置预先需要的注册表项,以避免权限问题:

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"


根据MSDN,只是对此答案的更新:“要在Windows Vista及更高版本或Windows Server 2003中创建事件源,您必须具有管理权限”。

答案 1 :(得分:4)

我使用PowerShell脚本创建适当的源...

$source = "FoToIaW"
if ([System.Diagnostics.EventLog]::SourceExists($source) -eq $false) 
{
  [System.Diagnostics.EventLog]::CreateEventSource($source, "Application")
}

答案 2 :(得分:2)

以管理员身份运行visual studio

  1. 右键单击visual studio图标
  2. 点击“以管理员身份运行”

答案 3 :(得分:1)

或使用此代码....

 public static void RunSnippet(string logName, string eventSource)
{
    // this will throw an exception if you don't have admin rights
    if (!EventLog.SourceExists(eventSource))
    {
        System.Diagnostics.EventLog.CreateEventSource(eventSource, logName);
        Console.WriteLine("Event Log and Source: {0},{1} were created successfully.",logName, eventSource);
    }
    else
    {
        Console.WriteLine("Event log/source: {0}/{1} already exists",logName, eventSource);
    }
    Console.WriteLine("Done");

}
