I'm very new to the log4net, and I am trying to create several files and log to them accordingly with my method calls and here is my code:
private static readonly ILog firstlog = LogManager.GetLogger("Data"); private static readonly ILog secondlog = LogManager.GetLogger("General");
and then I log like this:
firstlog.Info("some message"); secondlog.Info("some message");
and here is my configuration file:
<appender name="General" type="log4net.Appender.RollingFileAppender">
<file type="log4net.Util.PatternString" value="C:\logs\myfile1.log"/>
<param name="Threshold" value="DEBUG"/>
<appendToFile value="true"/>
<rollingStyle value="Size"/>
<maxSizeRollBackups value="10"/>
<maximumFileSize value="10MB"/>
<staticLogFileName value="true"/>
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %method %-5level %logger – %message%newline"/>
</layout>
</appender>
<appender name="Data" type="log4net.Appender.RollingFileAppender">
<file type="log4net.Util.PatternString" value="C:\logs\myfile2.log"/>
<param name="Threshold" value="DEBUG"/>
<appendToFile value="true"/>
<rollingStyle value="Size"/>
<maxSizeRollBackups value="10"/>
<maximumFileSize value="10MB"/>
<staticLogFileName value="true"/>
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %method %-5level %logger – %message%newline"/>
</layout>
</appender>
<logger name="general">
<appender-ref ref="General"/>
</logger>
<logger name="data">
<appender-ref ref="Data"/>
</logger>
<root>
<appender-ref ref="Data"/>
</root>
And they are all logged in one file and the other two files are empty. Why is this?
What am I doing wrong?
Try removing the line
<appender-ref ref="Data"/>
from the node...

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

<level value="ALL" />
<appender-ref ref="RollingLogFileAppender" />
</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
This question already has answers here:
How I can set log4net to log my files into different folders each day?
(5 answers)
Closed 7 years ago.
Is it possible to create a log path everyday which writes the logs in the following folder format.
D:\Logs\yyyyMMdd\App1\App.txt
Will Log4Net create the path if it does not exist. ?
I tried the following, but it does't seem to work.
<appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
<file value="D:\Logs\" />
<appendToFile value="true" />
<datePattern value="yyyyMMdd'\App1\App.txt'" />
<rollingStyle value="Date" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date{ABSOLUTE} [%logger] %level - %message%newline%exception" />
</layout>
</appender>
Thanks in advance.
You can introduce your own appender:
namespace CustomLogging
{
public class CustomAppender : log4net.Appender.RollingFileAppender
{
protected override void OpenFile(string fileName, bool append)
{
string baseDirectory = Path.GetDirectoryName(fileName);
string fileNameOnly = Path.GetFileName(fileName);
string newDirectory = Path.Combine(baseDirectory, DateTime.Now.ToString("yyyyMMdd"));
string newFileName = Path.Combine(newDirectory, fileNameOnly);
base.OpenFile(newFileName, append);
}
}
}
and then
<appender name="CustomAppender" type="CustomLogging.CustomAppender">
<file type="log4net.Util.PatternString" value="Logs\Client"/>
<appendToFile value="true"/>
<rollingStyle value="Composite"/>
<datePattern value="-HHmmss"/>
<maxSizeRollBackups value="40"/>
<maximumFileSize value="1MB"/>
<countDirection value="1"/>
<encoding value="utf-8"/>
<staticLogFileName value="false"/>
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date{HH:mm:ss.fff}|%-5level|%message%newline"/>
</layout>
</appender>
Try this solution but only XAML
<appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
<lockingModel type="log4net.Appender.FileAppender+MinimalLock"/>
<file value="logs\" />
<datePattern value="dd.MM.yyyy'.log'" />
<staticLogFileName value="false" />
<appendToFile value="true" />
<rollingStyle value="Composite" />
<maxSizeRollBackups value="10" />
<maximumFileSize value="5MB" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline" />
</layout>
</appender>
I'm trying to get output from for errors to show up both in an appended logfile but also in the debug window. The logfile stuff is working correctly, but nothing every shows up in the debug window.
First, here is my config
<log4net>
<!--
This writes the log information to the console window. It only logs events
that are at least at the INFO level (which would mean that DEBUG events are not
captured.
-->
<appender name="ConsoleAppender" type="log4net.Appender.ConsoleAppender">
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date{ABSOLUTE} [%thread] %level %logger - %message%newlineExtra Info: %property{testProperty}%newline%exception"/>
</layout>
<filter type="log4net.Filter.LevelRangeFilter">
<levelMin value="DEBUG"/>
<levelMax value="FATAL"/>
</filter>
</appender>
<!--
This stores information in the logfile.txt file. It only captures log events
that contain the key word test or error.
-->
<appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
<file value="C:\TOPS\LOGFILES\logfile.txt"/>
<appendToFile value="true"/>
<rollingStyle value="Size"/>
<maxSizeRollBackups value="5"/>
<maximumFileSize value="10MB"/>
<staticLogFileName value="true"/>
<filter type="log4net.Filter.StringMatchFilter">
<stringToMatch value="test"/>
</filter>
<filter type="log4net.Filter.StringMatchFilter">
<stringToMatch value="error"/>
</filter>
<filter type="log4net.Filter.DenyAllFilter"/>
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %level %logger - %message%newline%exception"/>
</layout>
</appender>
<root>
<level value="DEBUG"/>
<appender-ref ref="ConsoleAppender"/>
<appender-ref ref="RollingFileAppender"/>
</root>
</log4net>
and then i call log4net in my code
log.Debug("Debug error logging", ex);
log.Info("Info error logging", ex);
log.Warn("Warn error logging", ex);
log.Error("Error error logging", ex);
log.Fatal("Fatal error logging", ex);
this creates 5 entries in my logfile, but no entries in my console window.
i have also modified my web.config so the appenders were as similar as possible, but i still get the exact same results
<log4net>
<!--

</layout>
</appender>

</layout>
</appender>
<root>
<level value="DEBUG"/>
<appender-ref ref="ConsoleAppender"/>
<appender-ref ref="RollingFileAppender"/>
</root>
</log4net>
any ideas on what i may have missed that is breaking the console output?
EDIT:
found the solution, as pointed out in the comments below by making3. i confused console appender and trace appender, which is what i was actually looking for. here's the updated config.

I want to create log files names with the following pattern:
SBRF_20120820.log
SBRF_20120821.log
SBRF_20120822.log
SBRF_20120823.log
In other words, create a new file for each day. So, I create the following configuration to do that:
<log4net>
<appender name="FileAppender" type="log4net.Appender.RollingFileAppender, log4net">
<file type="log4net.Util.PatternString" value="Logs/SBRF_%date{yyyyMMdd}.log" />
<appendToFile value="true" />
<rollingStyle value="Date" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date %-5level - %message%newline" />
</layout>
</appender>
<logger name="LogEmArquivo">
<level value="INFO" />
<appender-ref ref="FileAppender" />
</logger>
</log4net>
When I run the program, today for example, the file SBRF_20120823.log will be created. But in the following days the log keeps to write in the SBRF_20120823.log file, and the files that are created are:
SBRF_20120823.log.2012-08-23
SBRF_20120823.log.2012-08-24
SBRF_20120823.log.2012-08-25
SBRF_20120823.log.2012-08-26
And if I run the program tomorrow, the files that will be created are:
SBRF_20120824.log.2012-08-24
SBRF_20120824.log.2012-08-25
SBRF_20120824.log.2012-08-26
SBRF_20120824.log.2012-08-27
Why?
You do not put the date pattern in the <file> - that is the static part of the filename. You need to put it into the <datePattern>.
Also, if you are using log4net 1.2.11, you can use <preserveLogFileNameExtension> which puts the datePattern on the current file also.
I think this is what you want your configuration to look like:
<log4net>
<appender name="FileAppender" type="log4net.Appender.RollingFileAppender, log4net">
<file type="log4net.Util.PatternString" value="Logs/SBRF_.log"/>
<appendToFile value="true" />
<rollingStyle value="Date" />
<datePattern value="yyyyMMdd" />
<preserveLogFileNameExtension value="true"/>
<staticLogFileName value="false" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date %-5level - %message%newline" />
</layout>
</appender>
<logger name="LogEmArquivo">
<level value="INFO" />
<appender-ref ref="FileAppender" />
</logger>
Remove the <rollingStyle value="Date" />.
Don't think you change this behaviour with the RollingFileAppender, so you would have to create your own appender.
