Raygun with log4net not logging

asp.net, c#, log4net, raygun, raygun.io

Solution

You need to tell log4net to read the configuration, add the following line in you main method:

log4net.Config.XmlConfigurator(Watch = true);

Or put the following attribute in your assamblyinfo.cs:

[assembly: log4net.Config.XmlConfigurator(Watch = true)]

If that is not working you can enable log4net internal debugging to see what is going on in the log4net internal code:

<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>

Problem

I have a simple console app. Downloaded log4net nuget package as well as log4net raygun nuget package: https://www.nuget.org/packages/log4net.Raygun/. I've set up my app to log exceptions and info messages and I do get those in my log file, but NOT in raygun dashboard, Nor do I get emails from raygun.io. What am I doing wrong? ``` 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: ``` <?xml version="1.0" encoding="utf-8"?> <configuration> <configSections> <!-- log4net --> <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" /> </configSections> <log4net> <appender name="LogFileAppender" type="log4net.Appender.RollingFileAppender"> <file value="ErrorLog//ErrorLog.txt" /> <lockingModel type="log4net.Appender.FileAppender+MinimalLock" /> <appendToFile value="true" /> <rollingStyle value="Size" /> <maxSizeRollBackups value="2" /> <maximumFileSize value="1MB" /> <staticLogFileName value="true" /> <layout type="log4net.Layout.PatternLayout"> <param name="ConversionPattern" value="%d [%t] %-5p %c %m%n" /> </layout> </appender> <appender name="RaygunAppender" type="log4net.Raygun.RaygunAppender, log4net.Raygun"> <threshold value="DEBUG" /> <apiKey value="MY SUPER AWESOME KEY HERE" /> <!-- Attempt to send errors to raygun 15 times --> <retries value="15" /> <!-- Wait 1 minute between retry attempts --> <timeBetweenRetries value="00:01:00" /> <!-- Toggles whether to only send exceptions to raygun, or to also send messages logged to ERROR --> <onlySendExceptions value="false" /> <!-- Optional filters for filtering exceptions and messages before sending to raygun --> <!--<exceptionFilter value="SomeOtherAssembly.SensitiveInformationMessageFilter, SomeOtherAssembly" /> <renderedMessageFilter value="SomeOtherAssembly.SensitiveInformationMessageFilter, SomeOtherAssembly" />--> </appender> <root> <level value="ALL" /> <appender-ref ref="LogFileAppender" /> <appender-ref ref="RaygunAppender" /> </root> </log4net> <startup> <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" /> </startup> <runtime> <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1"> <dependentAssembly> <assemblyIdentity name="log4net" publicKeyToken="669e0ddf0bb1aa2a" culture="neutral" /> <bindingRedirect oldVersion="0.0.0.0-1.2.13.0" newVersion="1.2.13.0" /> </dependentAssembly> </assemblyBinding> </runtime> </configuration> ``` EDIT: I've added debugging and "XmlConfigurator.Configure();" this is what I get (However, still no errors show up in Raygun.io dashboard) : ``` ... 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.
