I'm using log4net v1.2 with a Windows Service App. My RollingFileAppender seems not to work. I'm pasting the logging sections of my service.exe.config below. Can anyone advise where I'm going wrong?
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net"/>
.....(lots of other config stuff)
<appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender,log4net" >
<param name="File" value="D:\\Trinity\\Booking\\OneDay_PostTrade\\logs\\Trinity.log" />
<param name="MaximumFileSize" value="20MB" />
<param name="MaxSizeRollBackups" value="10" />
<param name="StaticLogFileName" value="true" />
<param name="Threshold" value="ALL" />
<param name="RollingStyle" value="Composite" />
<param name="appendToFile" value="true" />
<layout type="log4net.Layout.PatternLayout,log4net">
<param name="ConversionPattern" value="%d [%t] %-5p %c - %m%n" />
</layout>
</appender>
...(stuff in between)
<root>
<level value="ALL" />
<appender-ref ref="ConsoleAppender" />
<appender-ref ref="RollingFileAppender" />
</root>
.....(stuff in between)
<logger name="CSFB.PostTradeRulesEngine">
<level value="ALL"/>
</logger>
The user your windows service is running as might not have write permission for the log file.
Another possibility is that you forgot to execute XmlConfigurator.Configure();
try writing:
<log4net debug="true">
it will post all errors to console.
thanks to everyone who responded. I dont know what i changed but my logging has started working fine.
Posting my logging sections. I didnt change anything in the code, except a line in the AssemblyInfo.cs:
[assembly: log4net.Config.Domain(UseDefaultDomain=true)]
Thanks again.:)

A solution already exists that uses log4net with Common.Logging,
we have decided we want to swap out log4net and swap in Serilog.
In App.config
--<factoryAdapter type="Common.Logging.Log4Net.Log4NetLoggerFactoryAdapter, Common.Logging.Log4Net1215">
++<factoryAdapter type="Common.Logging.Serilog.SerilogFactoryAdapter, Common.Logging.Serilog">
Seems easy enough, but then as I continued looking through our existing App.config file I came across less obvious areas of transition.
--<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/>
++<section name="serilog" type="Serilog.Configuration.LoggerSettingsConfiguration, serilog"/><!--Not sure if equivalent-->
This change does not seem as obviously right and is really just a shot in the dark. In fact, I'm pretty sure it is wrong.
Then there is the actual config of the rolling file appender:
<log4net>
<appender name="LM" type="log4net.Appender.RollingFileAppender">
<file type="log4net.Util.PatternString" value="%property{LogFileName}\\Program\Logs\\specificProgram.log" />
<param name="RollingStyle" value="Size" />
<param name="AppendToFile" value="true" />
<param name="MaxSizeRollBackups" value="5" />
<param name="MaximumFileSize" value="10MB" />
<param name="StaticLogFileName" value="true" />
<layout type="log4net.Layout.PatternLayout">
<param name="ConversionPattern" value="%d{MM-dd-yy HH:mm:ss.fff} [%thread] %-5p - %c{1} - %m%n" />
</layout>
</appender>
<appender name="QuickLog" type="log4net.Appender.RollingFileAppender">
<file type="log4net.Util.PatternString" value="%property{LogFileName}\\Program\Logs\\QuickLog.log" />
<param name="RollingStyle" value="Size" />
<param name="AppendToFile" value="true" />
<param name="MaxSizeRollBackups" value="5" />
<param name="MaximumFileSize" value="10MB" />
<param name="StaticLogFileName" value="true" />
<lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
<layout type="log4net.Layout.PatternLayout">
<param name="ConversionPattern" value="%d{MM-dd-yy HH:mm:ss.fff} [%thread] %-5p - %c{1} - %m%n" />
</layout>
</appender>
<logger name="LM">
<level value="TRACE"/>
<appender-ref ref="LM"/>
</logger>
<logger name="QuickLog">
<level value="TRACE"/>
<appender-ref ref="QuickLog"/>
</logger>
</log4net>
I couldn't find any blogs or documentation on swapping from log4net to Serilog that use mainly App.config for settings...
In the code behind, we have a pretty simple initialization
if (null == s_logger || null == quick_logger)
{
log4net.GlobalContext.Properties["LogFileName"] = MachineConfiguration.DataPath;
s_logger = CommonLogging.LogManager.GetLogger("LM");
quick_logger = CommonLogging.LogManager.GetLogger("QuickLog");
}
Serilog also seems to lack a GlobalContext, or at least I haven't found the equivalent yet looking through the library.
Is there any mapping of App.config changes from log4net to Serilog? or somewhere to look up what the equivalent types or params are between the two libraries?
I know I can't be the first person to do this swap, but I am having trouble finding documentation that matches what we currently have in place.
I have a problem.
Log4j dont want write to console and to file with system variable in path. Only write to file with simple path.
Configuration of my log4j.
<appender name="console" class="org.apache.log4j.ConsoleAppender">
<param name="Target" value="System.out" />
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%-5p: %c - %m%n" />
</layout>
</appender>
<appender name="file" class="org.apache.log4j.DailyRollingFileAppender">
<!-- <param name="file" value="d:/lv-098_JAVA/logs/log.log" /> -->
<param name="file" value="${LV098_JAVA}/src/main/resources/logs/log.log" />
<param name="DatePattern" value="'.'yyyy-MM-dd" />
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%d [%t] %-5p (%F:%L:%M) %c{1} %m%n" />
</layout>
<!-- Root Logger -->
<root>
<priority value="info" />
<appender-ref ref="file1" />
<appender-ref ref="console" />
</root>
</log4j:configuration>
You are declaring
appender name="file" class="org.apache.log4j.DailyRollingFileAppender"
and in root tag you write
appender-ref ref="file1"
As there is no such file1. Due to this log4j is not working for you.
I found where problem is. It is in Jboss, because jboss have his own logger and it doesn't allow to write to console. You must change configuration of Jboss logger. But I don't know why it does not allow to use system variable.
In my case,
I have configured my log4j.xml like this.
<appender name="FILE" class="org.apache.log4j.RollingFileAppender">
<errorHandler class="org.apache.log4j.helpers.OnlyOnceErrorHandler" />
<param name="File" value="F:/myLogger.log" />
<param name="Append" value="true" />
<param name="MaxFileSize" value="20000KB" />
<param name="MaxBackupIndex" value="400" />
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%-5p: %d{dd MMM yyyy HH:mm:ss.SSS} %-5l - %m%n%n" />
</layout>
</appender>
<!-- Root Logger -->
<root>
<priority value="error" />
<appender-ref ref="FILE" />
</root>
and put log4.xml file in source package.
but logger file is not created at specified folder.Let me know the exact path.
(it may be tha t i am using some external JAR which may have log4j.xml) so how to give priority to root application log4j.xml file.
I have a class which events I want to log. Say, there are 2 levels: debug and error. How can I log errors to an errorFile and debug info to a debugFile?
So that I use log4j.xml there is a filter mechanism, but it seems to work only for different categories not inside one class.
Please, help to newbie. =)
You have to define and use two appender with different Threshold like this:
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">
<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/">
<!-- Error -->
<appender name="ErrorFile"
class="org.apache.log4j.RollingFileAppender">
<param name="Threshold" value="error"/>
<param name="file" value="log.err" />
<param name="MaxFileSize" value="10MB" />
<param name="MaxBackupIndex" value="10" />
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%-5p %d %C.%M (%L) - %m%n" />
</layout>
</appender>
<appender name="LogFile"
class="org.apache.log4j.RollingFileAppender">
<param name="Threshold" value="debug"/>
<param name="file" value="log.log" />
<param name="MaxFileSize" value="10MB" />
<param name="MaxBackupIndex" value="10" />
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%-5p %d %C.%M (%L) - %m%n" />
</layout>
</appender>
<logger name="foo.bar" additivity="false">
<level value="debug" />
<appender-ref ref="LogFile" />
<appender-ref ref="ErrorFile" />
</logger>
<root>
<priority value="warn" />
<appender-ref ref="ErrorFile"/>
</root>
</log4j:configuration>
This question is also answered in the log4j FAQs.
Just found the LogToAppenderByLevel solution (here) which may be also helpful for you.
I've set up a logfileAppender and a consoleAppender in my log4net config for my application. I would like the logfile appender to only write ERROR messages and above and the console appender to write DEBUG and above.
My config is:
<log4net debug="false">
<appender name="LogFileAppender" type="log4net.Appender.FileAppender,log4net" >
<param name="File" value="log.txt" />
<param name="AppendToFile" value="true" />
<layout type="log4net.Layout.PatternLayout,log4net">
<param name="ConversionPattern" value="%d %M - %m%n" />
</layout>
<threshold value="ERROR"/>
</appender>
<appender name="ConsoleAppender" type="log4net.Appender.ConsoleAppender" >
<layout type="log4net.Layout.PatternLayout">
<param name="ConversionPattern" value="%d %m%n" />
</layout>
</appender>
<root>
<priority value="DEBUG" />
<appender-ref ref="ConsoleAppender" />
<appender-ref ref="LogFileAppender" />
</root>
</log4net>
I'm finding that both ERROR and DEBUG is being output to my logfile appender. How to restrict it to only ERROR?
Note also that the level tag in the logger doesn't work the same way as threshold or a LevelMatchFilter.
Level indicates what log statements that actually will be generated. This is what you can test on in you code.
Threshold on the other hand, filters away all log messages that falls below your threshold.
This means that having a threshold that is higher than the highest logger level makes no sense. I have seen many times how one sets a level of INFO (because that is what most appenders will use), and then create an appender that has a threshold of DEBUG. And then you are surprised when no DEBUG messages actually appears on the appender...
To get very specific filtering for an appender, you need to configure a LevelMatchFilter or a LevelRangeFilter for the logfile appender to filter the events which are actually output.
For example:
<filter type="log4net.Filter.LevelRangeFilter">
<levelMin value="ERROR"/>
<levelMax value="FATAL"/>
</filter>
or
<filter type="log4net.Filter.LevelMatchFilter">
<levelToMatch value="ERROR"/>
</filter>
put one of these inside your <appender> tag, and this should work for you:
<appender name="LogFileAppender" type="log4net.Appender.FileAppender,log4net" >
<filter type="log4net.Filter.LevelMatchFilter">
<levelToMatch value="ERROR"/>
</filter>
<param name="File" value="log.txt" />
<param name="AppendToFile" value="true" />
<layout type="log4net.Layout.PatternLayout,log4net">
<param name="ConversionPattern" value="%d %M - %m%n" />
</layout>
<threshold value="ERROR"/>
</appender>
Note: Updated to remove mistake pointed out by kgiannakakis.
I've created a sample console application using your log4net config and I'm getting the exact behaviour you appear to be wanting....
using System;
using System.IO;
using log4net;
using log4net.Config;
namespace SO_1171258
{
class Program
{
private static readonly ILog log = LogManager.GetLogger(typeof(Program));
static void Main()
{
XmlConfigurator.ConfigureAndWatch(new FileInfo(AppDomain.CurrentDomain.GetData("APP_CONFIG_FILE").ToString()));
log.Error(new Exception("error log statment"));
log.Debug("debug log statment");
}
}
}
When I run this application, the only thing in the logfile is:
2014-01-27 15:02:51,387 Main - System.Exception: error log statment
And to the screen I see:
2014-01-27 15:05:52,190 System.Exception: error log statment
2014-01-27 15:05:52,218 debug log statment
Here is the entirety of my app.config file:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<configSections>
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net"/>
</configSections>
<log4net debug="false">
<appender name="LogFileAppender" type="log4net.Appender.FileAppender,log4net" >
<param name="File" value="log.txt" />
<param name="AppendToFile" value="true" />
<layout type="log4net.Layout.PatternLayout,log4net">
<param name="ConversionPattern" value="%d %M - %m%n" />
</layout>
<threshold value="ERROR"/>
</appender>
<appender name="ConsoleAppender" type="log4net.Appender.ConsoleAppender" >
<layout type="log4net.Layout.PatternLayout">
<param name="ConversionPattern" value="%d %m%n" />
</layout>
</appender>
<root>
<priority value="DEBUG" />
<appender-ref ref="ConsoleAppender" />
<appender-ref ref="LogFileAppender" />
</root>
</log4net>
</configuration>
The answers you are receiving are partly correct. The Threshold is only used to set a lower limit on the level appended. A threshold of ERROR will actually receive ERROR and FATAL (which is "above" ERROR).
You do want to implement a LevelMatchFilter with a level value of "ERROR" (and "DEBUG" for the other appender). However, you must also add a DenyAllFilter to the end of your filter chain.
For example:
<appender name="LogFileAppender" type="log4net.Appender.FileAppender,log4net" >
<param name="File" value="log.txt" />
<param name="AppendToFile" value="true" />
<layout type="log4net.Layout.PatternLayout,log4net">
<param name="ConversionPattern" value="%d %M - %m%n" />
</layout>
<filter type="log4net.Filter.LevelMatchFilter">
<levelToMatch value="ERROR" />
</filter>
<filter type="log4net.Filter.DenyAllFilter" />
</appender>
I've had to implement the DenyAllFilter since log4net 1.2.10 (you can see the question I had on this topic here).
You need to use additivity property. See here for an example. You need to define two loggers.
