[英]Raygun with log4net not logging
我有一個簡單的控制台應用程序 下載了log4net nuget包以及log4net raygun nuget包: https ://www.nuget.org/packages/log4net.Raygun/。 我已經設置了我的應用程序來記錄異常和信息消息,我確實在我的日志文件中得到了這些,但不是在raygun儀表板中,我也沒有收到來自raygun.io的電子郵件。 我究竟做錯了什么?
private static readonly ILog Log = LogManager.GetLogger(MethodBase.GetCurrentMethod().DeclaringType);
private static void CurrentDomain_UnhandledException(object sender, UnhandledExceptionEventArgs e)
{
Log.Error(e);
}
private static void Main(string[] args)
{
XmlConfigurator.Configure();
// Unhandled exceptions
AppDomain.CurrentDomain.UnhandledException += CurrentDomain_UnhandledException;
throw new Exception("test exception");
}
Web.Config中:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<configSections>
<!-- log4net -->
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />

編輯:我添加了調試和“XmlConfigurator.Configure();” 這是我得到的(但是,Raygun.io儀表板中仍然沒有出現錯誤):
...
log4net: RaygunAppender: Building Raygun message
log4net: RaygunAppender: Resolving application assembly
log4net: RaygunAppender: No exception object found in error, creating raygun error message from the rendered message and calling class
log4net: RaygunAppender: Sending Raygun message in a background task. Retries: '15', TimeBetweenRetries: '00:01:00'
您需要告訴log4net讀取配置,在main方法中添加以下行:
log4net.Config.XmlConfigurator(Watch = true);
或者在assamblyinfo.cs中添加以下屬性:
[assembly: log4net.Config.XmlConfigurator(Watch = true)]
如果這不起作用,您可以啟用log4net內部調試以查看log4net內部代碼中發生的情況:
<configuration>
...
<appSettings>
<add key="log4net.Internal.Debug" value="true"/>
</appSettings>
...
<system.diagnostics>
<trace autoflush="true">
<listeners>
<add
name="textWriterTraceListener"
type="System.Diagnostics.TextWriterTraceListener"
initializeData="C:\tmp\log4net.txt" />
</listeners>
</trace>
</system.diagnostics>
</configuration>
一些建議。 您的CurrentDomain_UnhandledException
處理程序將UnhandledExceptionEventArgs
對象傳遞給log4net以進行日志記錄,而不是事件上的ExceptionObject
。 對於log4net.Raygun
來處理異常,你可能想要這樣的東西:
private static void CurrentDomain_UnhandledException(object sender, UnhandledExceptionEventArgs e)
{
Log.Error(e.ExceptionObject);
}
您遇到的另一個問題是默認情況下log4net.Raygun
會在后台任務中將消息發送給Raygun。 在您的簡單控制台應用程序中,您的應用程序在后台任務完成之前退出和卸載,因此消息實際上從未發送過。 您可以通過將以下設置添加到appender配置來禁用后台發送錯誤:
<appender name="RaygunAppender" type="log4net.Raygun.RaygunAppender, log4net.Raygun">
...
<sendInBackground value="false" />
...
</appender>
