How do I configure log4net or my Gallio test runners (Icarus and Echo) to use a different logging level for the Gallio Execution Log and my own file appender. I want my log file to have a DEBUG log level and Gallio to have an ERROR log level.
I thought this would work but Gallio is reading both appenders:
<log4net>
<appender name="Console" type="log4net.Appender.ConsoleAppender">
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%5level [%thread] (%file:%line) - %message%newline" />
</layout>
</appender>
<appender name="File" type="log4net.Appender.FileAppender">
<file value="test.log" />
<appendToFile value="false" />
<lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%5level [%thread] (%file:%line) - %message%newline" />
</layout>
</appender>
<logger name="TestNamespace">
<level value="DEBUG" />
<appender-ref ref="File" />
</logger>
<root>
<level value="ERROR" />
<appender-ref ref="Console" />
</root>
</log4net>
Gallio is redirecting console output to its Execution Log. So I needed to set the threshold of the ConsoleAppender to the level I want for the Gallio Execution Log.
<log4net>
<appender name="Console" type="log4net.Appender.ConsoleAppender">
<threshold value="ERROR"/>
<layout type="log4net.Layout.PatternLayout">
<!-- Pattern to output the caller's file name and line number -->
<conversionPattern value="%5level [%thread] (%file:%line) - %message%newline" />
</layout>
</appender>
<appender name="File" type="log4net.Appender.FileAppender">
<threshold value="DEBUG"/>
<file value="test.log" />
<appendToFile value="false" />
<lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%5level [%thread] (%file:%line) - %message%newline" />
</layout>
</appender>
<root>
<appender-ref ref="Console" />
<appender-ref ref="File" />
</root>
</log4net>

I have an solution which consist of multiple projects.its a desktop application I need to have two separate log4net configurations for those projects since one project contains a library that uses log4net itself. On one project log4net configured in App.config and other project it is configured in log4net.configuration file.
below is one configuration file

</logger>
</log4net>
those two log file load correctly but they all write on to the same log file seperatelog.txt
What i need is to have two separate files to create for those 2 configurations.
Seems you'll better define log4net configuration not in app.config but in dedicated XML files. Names of XML files can be composed according to some convention so your projects will know what log4net configuration XML is dedicated to each one.
You'll able to configure your log4net with XmlConfigurator.Configure(...) function
I'm trying to get name of the file with log by log4net, but I can't get my Appenders. This is my config:
<log4net>
<appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
<file value="name.log"/>
<appendToFile value="false"/>
<maximumFileSize value="10MB"/>
<maxSizeRollBackups value="0"/>
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date %level %thread %logger - %message%newline"/>
</layout>
</appender>
<appender name="ColoredConsoleAppender" type="log4net.Appender.ColoredConsoleAppender">
<mapping>
<level value="ERROR"/>
<foreColor value="Red, HighIntensity"/>
</mapping>
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date %level %thread %logger - %message%newline"/>
</layout>
</appender>
<root>
<level value="DEBUG"/>
<appender-ref ref="RollingFileAppender"/>
<appender-ref ref="ColoredConsoleAppender"/>
</root>
</log4net>
This is the code for getting count of appenders:
((Hierarchy)LogManager.GetRepository()).GetAppenders().Length.ToString();
But it gives me 0.
Logging works perfectly, so config works for logging. Do you have any ideas how to get the appenders or file name "name.log" from config without appenders? Thank you.
Is it possible you're fetching the appenders before your call to Configure?
Using the config you provided:
int count;
count = LogManager.GetRepository().GetAppenders().Length; // 0
XmlConfigurator.Configure();
count = LogManager.GetRepository().GetAppenders().Length; // 2
I'm trying to have 2 log files, with my application logging to either by specifying a logger name in code.
The problem is it never logs to the file I'm trying to target, instead it always logs to the last declared appender in the config (LogB in this case).
I have my config set up as follows:
<log4net>
<logger name="LogA">
<appender-ref ref="LogA"/>
<level value="DEBUG"/>
</logger>
<logger name="LogB">
<appender-ref ref="LogB"/>
<level value="DEBUG"/>
</logger>
<appender name="LogA" type="log4net.Appender.FileAppender">
<file value="E:\Logs\LogA.log" />
<appendToFile value="true" />
<rollingStyle value="Size" />
<maxSizeRollBackups value="5" />
<maximumFileSize value="10MB" />
<staticLogFileName value="true" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline" />
</layout>
</appender>
<appender name="LogB" type="log4net.Appender.FileAppender">
<file value="E:\Logs\LogB.log" />
<appendToFile value="true" />
<rollingStyle value="Size" />
<maxSizeRollBackups value="5" />
<maximumFileSize value="10MB" />
<staticLogFileName value="true" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline" />
</layout>
</appender>
<root>
<level value="DEBUG" />
<appender-ref ref="LogA" />
</root>
<root>
<level value="DEBUG" />
<appender-ref ref="LogB" />
</root>
</log4net>
Then in my code when I create a logger:
private static readonly ILog logA = LogManager.GetLogger("LogA");
log.Debug("This should log to LogA");
And in some other class:
private static readonly ILog logB = LogManager.GetLogger("LogB");
log.Debug("This should log to LogB");
But nothing is ever logged to the LogA file, it's always output to the LogB file (or whatever happens to appear last in the config).
What is it I'm missing?
For some reason it didn't appear to like the multiple root nodes. When I used this setup instead (keeping the appender nodes), it worked:
<root>
<level value="ALL" />
<appender-ref ref="SomeRootAppender" />
</root>
<logger additivity="false" name="LogA">
<level value="DEBUG"/>
<appender-ref ref="LogA" />
</logger>
<logger additivity="false" name="LogB">
<level value="DEBUG"/>
<appender-ref ref="LogB" />
</logger>
I have an application that uses log4net. I dump debug to a file as well as stdout.
When launching the application normally, I see all the messages in the output section as well as in the file.
If I create a class/ run a function that writes something to the log in the immediate window, I do not see anything in the Output nor in the Immediate window. I do see the log in the file though.
Is there any way I could fix it so I will be able to see these messages in the Immediate window?
Log4net configuration:
<log4net>
<root>
<level value="DEBUG"/>
<appender-ref ref="FileAppender"/>
<appender-ref ref="ConsoleAppender"/>
<appender name="ConsoleAppender" type="log4net.Appender.ConsoleAppender">
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date{dd.MM.yyyy HH:mm:ss.ffff} [%thread] %level %logger%exception - %message%newline"/>
</layout>
</appender>
<appender name="FileAppender" type="log4net.Appender.RollingFileAppender">
<file value="logs/log.txt" />
<appendToFile value="true" />
<rollingStyle value="Size" />
<maxSizeRollBackups value="1" />
<maximumFileSize value="1MB" />
<staticLogFileName value="true" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date{dd.MM.yyyy HH:mm:ss.ffff} [%thread] %level %logger%exception - %message%newline"/>
</layout>
</appender>
</root>
</log4net>
Add a DebugAppender to your configuration in order to have messages appear in the Immediate window (I tested this on VS2013)
<root>
<level value="DEBUG" />
<appender-ref ref="FileAppender" />
<appender-ref ref="ConsoleAppender" />
<appender-ref ref="DebugAppender" />
</root>
<appender name="DebugAppender" type="log4net.Appender.DebugAppender">
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date{dd.MM.yyyy HH:mm:ss.ffff} [%thread] %level %logger%exception - %message%newline" />
</layout>
</appender>
I have two log files written from my application, which have multiple assemblies in the following manner:
Assembly1 log -> MainLog.log
Assembly2 log -> MainLog.log
Assembly3 log -> MainLog.log
Assembly4 log -> MainLog.log
Assembly5 log -> SubLog.log
Assembly6 log -> SubLog.log
The log files get written correctly, but the problem here is, the SubLog entries get written into the MainLog file as well. I don't want this kind of logging duplication to happen. This is my log4net configuration.
<log4net>
<appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
<file value="Logs//MainLog.txt" />
<appendToFile value="true" />
<maxSizeRollBackups value="10" />
<maximumFileSize value="100KB" />
<rollingStyle value="Size" />
<staticLogFileName value="true" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%M %date [%thread] %-5level %logger [%ndc] - %message %C, %F, %l, %L %M %newline" />
</layout>
</appender>
<appender name="NewForEveryRun" type="log4net.Appender.FileAppender">
<file type="log4net.Util.PatternString" value="Logs//SubLog-%processid.txt"/>
<appendToFile value="true" />
<maximumFileSize value="10MB" />
<staticLogFileName value="true" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %-5level %logger - %message%newline" />
</layout>
</appender>
<logger name="Assembly5">
<level value="DEBUG"/>
<appender-ref ref="NewForEveryRun"/>
</logger>
<logger name="Assembly6">
<level value="DEBUG"/>
<appender-ref ref="NewForEveryRun"/>
</logger>
<root>
<level value="DEBUG" />
<appender-ref ref="RollingLogFileAppender" />
</root>
For Assembly5 and Assembly6, I've specified the appender NewForEveryRun. In addition to this, I've kept the root, so that the rest of the assemblies are logged according to configuration specified in the RollingLogFileAppender appender. I guess, the root element is logging all the assemblies by default, even if I mention different logger for other assemblies. Is there any way to block the logging of Assembly5 and Assembly6 from root?
Got it! The loggers should look like this:
<logger name="Assembly5" additivity="false">
<level value="DEBUG"/>
<appender-ref ref="NewForEveryRun"/>
</logger>
<logger name="Assembly6" additivity="false">
<level value="DEBUG"/>
<appender-ref ref="NewForEveryRun"/>
</logger>
Setting additivity as false is the solution. No more duplicate logging :)
