I use log4net to log the errors in my web application and it works fine. However if I place the same code in website I get error "Unrecognized configuration section log4net"
here is my web.config section
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,Log4net" requirePermission="false"/>
<root>
<level value="RELEASE" />
<appender-ref ref="LogFileAppender" />
</root>
<appender name="LogFileAppender" type="log4net.Appender.RollingFileAppender" >
<param name="File" value="D:\ESSReport\Logs\ESSlog.log" />
<param name="AppendToFile" value="true" />
<rollingStyle value="Size" />
<maxSizeRollBackups value="5" />
<maximumFileSize value="4MB" />
<staticLogFileName value="true" />
<layout type="log4net.Layout.PatternLayout">
<param name="ConversionPattern" value="%newline%-5p%d{yyyy-MM-dd hh:mm:ss} [%thread] [%logger] [%line] %newline - %message" />
</layout>
</appender>
I have added dll to my website
You are probably missing configuration section registration.
Here is sample code how you can register custom section:
<configuration>
<configSections>
<sectionGroup name="LoggerConfiguration">
<section name="GPWFLogger" type="GP.Solutions.WF.Entities.LoggerConfiguration,GPWFLogger" allowDefinition="Everywhere" allowLocation="true"/>
</sectionGroup>
</configSections>
<LoggerConfiguration>
<GPWFLogger
ConnectionStringName="ASPNETDB"
LogLevel="Full"
LogPrimaryTarget="SqlServer"
LogFilePath="GPWFwebClient.log" />
</LoggerConfiguration>
Take notice that LoggerConfiguration is registred inside sectionGroup.
You can use this principle in your case.

I want to implement logging function into a class library, which is itself referenced in a webapplication. I tried to add app.config and did everything needed, but its not logging any message, log4net simply does nothing.
Here is my app.config
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<configSections>
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />
</configSections>
<log4net debug="true">
<appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
<file value="D:\StagingPortal2012\Communicationlogs\TestProjlog4net.txt" />
<appendToFile value="true" />
<rollingStyle value="Size" />
<maxSizeRollBackups value="10" />
<maximumFileSize value="20MB" />
<staticLogFileName value="true" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%newline%-5p %d %-22.22c{1} %-18.18M - %m%n" />
</layout>
</appender>
<root>
<appender-ref ref="RollingLogFileAppender" />
<level value="DEBUG"></level>
</root>
</log4net>
<appSettings>
<add key="log4net.Internal.Debug" value="true" />
</appSettings>
</configuration>
And Assembly.Info.cs
[assembly: log4net.Config.XmlConfigurator(ConfigFile = "App.config")]
And Communicator.cs(Where i using log4net for writing log)
private static readonly ILog Log = LogManager.GetLogger(
System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
I have an ASP.NET web app that uses log4net to log to various appenders. I have successfully added a SmtpAppender with a LevelEvaluator and can get e-mails to be sent with this; however if I replace this with a TimeEvaluator I cannot get e-mails to send.
My appender with the LevelEvaluator looks like this (this is working):
<appender name="EmailErrorAppender" type="log4net.Appender.SmtpAppender">
<to value="to#myemail" />
<from value="from#myemail" />
<subject value="Alert Subject" />
<smtpHost value="mymailhost" />
<bufferSize value="50" />
<lossy value="true" />
<filter type="log4net.Filter.LevelRangeFilter">
<levelMin value="ERROR" />
<levelMax value="FATAL" />
</filter>
<evaluator type="log4net.Core.LevelEvaluator">
<threshold value="ERROR"/>
</evaluator>
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %-5level %logger%newline%newline" />
</layout>
</appender>
The problematic appender with the TimeEvaluator looks like this (this is not working):
<appender name="EmailErrorAppender" type="log4net.Appender.SmtpAppender">
<to value="to#myemail" />
<from value="from#myemail" />
<subject value="Alert Subject" />
<smtpHost value="mymailhost" />
<bufferSize value="50" />
<lossy value="true" />
<filter type="log4net.Filter.LevelRangeFilter">
<levelMin value="ERROR" />
<levelMax value="FATAL" />
</filter>
<evaluator type="log4net.Core.TimeEvaluator">
<interval value="30"/>
</evaluator>
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %-5level %logger%newline%newline" />
</layout>
</appender>
I've checked log4net's internal debug and it says it is loading it fine.
I would appreciate any help - is TimeEvaluator broken in an ASP.NET web context?
I have following configuration:
<log4net>
<root>
<level value="All"/>
<appender-ref ref="RollingFileAppender"/>
</root>
<appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
<file value="mylog.log"/>
<appendToFile value="true"/>
<preserveLogFileNameExtension value="true"/>
<rollingStyle value="Composite"/>
<datePattern value=".yyyyMMdd"/>
<maximumFileSize value="5MB"/>
<countDirection value="1"/>
<maxSizeRollBackups value="-1"/>
<staticLogFileName value="false"/>
<layout type="log4net.Layout.PatternLayout">
<param name="ConversionPattern" value="%date [%thread] %-5level %logger - %message%newline"/>
</layout>
</appender>
</log4net>
And the following code in global.asax:
Sub Application_Start()
AreaRegistration.RegisterAllAreas()
RegisterGlobalFilters(GlobalFilters.Filters)
RegisterRoutes(RouteTable.Routes)
BasicConfigurator.Configure();
LogManager.GetLogger(typeof(Global_asax)).Error("Logger configured")
End Sub
For the tag file in configuration above. I have tried C:\my folder\mylog.log as well as what is seen above mylog.log
However, I do not see this file generated anywhere and there are no exceptions.
Environment: VS 2013 ASP.Net VB. Running via Debug menu. When I run IISExpress is started by VS2013 and site runs. but no log is seen.
I have tried various combinations for the file tag but nothing works.
Can someone help please?
This is final version of what I ended up doing that worked:
<log4net>
<root>
<level value="ALL"/>
<appender-ref ref="RollingFileAppender"/>
</root>
<appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
<file value="logs\log4net.log"/>
<datePattern value="yyyy-MM-dd'-FULL.log'" />
<appendToFile value="true"/>
<preserveLogFileNameExtension value="true"/>
<rollingStyle value="Size"/>
<maximumFileSize value="250KB"/>
<maxSizeRollBackups value="-1"/>
<staticLogFileName value="false"/>
<layout type="log4net.Layout.PatternLayout">
<param name="ConversionPattern" value="%date [%thread] %-5level %logger - %message%newline"/>
</layout>
</appender>
</log4net>
And
XmlConfigurator.Configure()
LogManager.GetLogger(typeof(Global_asax)).Error("Logger configured")
This logged to log\log4net.log in the application directory (i.e. where my code is )
This used to work for me (I've switched to the lighter and better configurable NLog), log rolled daily, was written in a subfolder named "Logs" under the app's path.
<appender name="RollingDebugAppender" type="log4net.Appender.RollingFileAppender">
<file value="Logs\" />
<datePattern value="yyyy-MM-dd'-FULL.log'" />
<staticLogFileName value="false" />
<appendToFile value="true" />
<rollingStyle value="Composite" />
<maxSizeRollBackups value="100" />
<maximumFileSize value="5MB" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline" />
</layout>
</appender>
You should turn on log4net's internal debugging to figure out what's failing...
Sample web.config
<?xml version="1.0" encoding="utf-8" ?>
<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:\log4net_internal.log"/>
</listeners>
</trace>
</system.diagnostics>
</configuration>
More information available here on the troubleshooting section.
*_%date{yyyyMMdd}.log
below is the key, if this is missing u will see logs like above
<?xml version="1.0" encoding="utf-8" ?>
<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:\log4net_internal.log"/>
**<staticLogFileName value="false" />**
</listeners>
</trace>
</system.diagnostics>
</configuration>
Adding debug = "true" to the <log4net> tag (i.e. <log4net debug="true"> ) can help to solve the problem
Probably a very simple setup, but I've tried to setup Log4Net. In my web.config I have:
<log4net>
<appender name="File" type="log4net.Appender.RollingFileAppender">
<file value="Logs\\Log4Net.log" />
<appendToFile value="true" />
<rollingStyle value="Date" />
<datePattern value="yyyyMMdd-HHmm" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline" />
</layout>
</appender>
<logger name="File">
<level value="All" />
<appender-ref ref="LogFileAppender" />
</logger>
<root>
<level value="ALL"/>
<appender-ref ref="FileAppender"/>
</root>
</log4net>
I have added the following to my configsections:
<configSections>
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/>
</configSections>
The following in global.asax:
log4net.Config.XmlConfigurator.Configure();
The following is on my default.aspx:
ILog alog = log4net.LogManager.GetLogger(typeof(_Default));
log4net.ILog logger = log4net.LogManager.GetLogger("File");
protected void Page_Load(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
SetupSeo();
}
alog.Error("this test");
logger.Error("Front page loaded for ip " + Request.UserHostAddress);
}
What is wrong?
I guess it is a Permission issue. The relevant directory do not have sufficent permissions so that ASP.NET can write to that.
To verify that, Enable log4net internal debugging by adding the below item to the <appSettings> section in the webconfig.
<add key="log4net.Internal.Debug" value="true"/>
Now add the below to the webconfig as well
<system.diagnostics>
<trace autoflush="true">
<listeners>
<add
name="textWriterTraceListener"
type="System.Diagnostics.TextWriterTraceListener"
initializeData="C:\myLogFolder\log4net.txt" />
</listeners>
</trace>
</system.diagnostics>
Make sure that myLogFolder folder in C drive have permissions so that ASP.NET can write to that. This will write the internal debugging message to this file. Run the app and see what happens.
hi i'm using log4net for logging my website.
Every day a new file is created like "filename.log24-06-2009"
this is the code in the web.config file:
<log4net>
<appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
<file value="App_Data\Missioni.log" />
<appendToFile value="true" />
<rollingStyle value="Composite" />
<!--<datePattern value="yyyy-MM-dd" />-->
<maxSizeRollBackups value="5" />
<maximumFileSize value="5MB" />
<layout type="log4net.Layout.PatternLayout">
<header value="[Header]
" />
<footer value="[Footer]
" />
<conversionPattern value="%date [%thread] %-5level %logger - %message%newline" />
</layout>
</appender>
<root>
<level value="DEBUG" />
<appender-ref ref="RollingLogFileAppender" />
</root>
</log4net>
How can i do for use a unique log file?
thanks
The question' a bit unclear, so please comment if I'm off. If you want to change how the files are created, uncomment the datePattern block and you can specify the file name layout, for example if you wanted the log to change monthly:
<datePattern value="yyyy-MM" />
When the pattern changes (midnight with the standard datePattern) a new file is created, change the pattern to so it only rolls to a new file when you want.
