I'm working on windows service. Recently added log4net dll to log all the activities but the problem is how can I stop creating new log file everyday? I don't need new log file everyday. All I need is common "OverallLog" file.In configuration I have set up two log files. One captures the overall log and another captures log for each run.
also can anyone explain what does maxsizerollbackups do?

I am using below config file for log generation
<configuration>
<configSections>

My expectation is to get the log file in below format
Current Log file name Test.log.
When it reaches to 5MB, expecting back up file name as below
Test_1.bak
:
"

Test_10.bak
I wanted my log file to be create for each date and if the log got to be bigger then 100mb then it will create a new file. Below is my setting and it will not create a new file.

My AssamblyInfo.cs have foolow row:
[assembly: log4net.Config.XmlConfigurator(ConfigFile = "log4net.config", Watch = true)]
In constructor of class I got object via Winsdor:
public class ACIStart
{
private ILogger Logger { get; set; }
public ACIStart(ILogger logger)
{
Logger = logger;
}
I don't have any exceptions, I just got a logger with all properties (IsDebbugEnabled, IsErrorEnabled ... ) as false.
My log no write anything to log file.
What could be the problem?
It could be that you need to add the loglevel in you root node:
<root>
<level value="DEBUG" />
...
I have a WinForm that it display log information but I want it to display to only INFO level but I want the log in the log file to contain DEBUG level as well.
Below is my configuration:
<?xml version="1.0" encoding="utf-8" ?>
<!-- This section contains the log4net configuration settings -->

<level value="INFO" />
<appender-ref ref="LogFileAppender" />
<appender-ref ref="ColoredConsoleAppender" />
<appender-ref ref="RichTextBoxAppender" />
</logger>
</log4net>
Right now it is set to INFO for both LogFileAppender and RichTextBoxAppender. I tried taking out the LogFileAppender in Gateway logger and move to another logger and set to "DEBUG" level for this new logger but it is still doing one or the other. How do I configure it so that the LogFileAppender has DEBUG level and RichTextBoxAppender has INFO level?
You should be able to add a filter to both of your appenders.
<filter type="log4net.Filter.LevelRangeFilter">
<levelMin value="INFO" />
<levelMax value="FATAL" />
</filter>
This way one appender will only log to a certain level while the other to a different level even though they are defined by the same logger.
I agree with #gwhitake that you can use the level range filter. I also want to add, however, that you can use the LevelMatch filter if you just want to select one level. This filter allows you to add another filter at the end of it as well so that you could create a filter that had two or more levels even if they aren't next to each other in the order.
For example, the following filter will capture only DEBUG and ERROR messages (just as an example):
<filter type="log4net.Filter.LevelMatchFilter">
<levelToMatch value="DEBUG"/>
</filter>
<filter type="log4net.Filter.LevelMatchFilter">
<levelToMatch value="ERROR"/>
</filter>
<filter type="log4net.Filter.DenyAllFilter" />
The one key here is that we need to have the DenyAllFilter at the end. This tells the logger that if it reaches this line, don't log it. That way it will log DEBUG messages, ERROR messages, and nothing else.
There are a lot of ways to manipulate the filter to get exactly what you want. Here is an article (full disclaimer: I wrote it) that shows you how to do a number of different things with the filter besides just level range:
http://www.codeproject.com/KB/dotnet/Log4net_Tutorial.aspx
I need to configure logger to write messages to several appenders with different Log Levels.
For ex. I want RefreshDataService to log detailed info to TransportFileAppender and Warnings and Errors to RollingFileAppender.
Also, I'm using buffering to improve logging performance.
I setup FilteredFileLog appender to forward Warnings to FileLog->RollingFileAppender.
But for RefreshDataService logger, all log messages including debug and Info getting logged to FileLog.
Can you help me to configure the RefreshDataService logger to log only Warn+ messages to FileLog? Thanks.
Below is excerpt from my log4net config.
<appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
<file value="${TEMP}\logs\client\${ENV}\client.log" />
<appendToFile value="true" />
<rollingStyle value="Size" />
<maxSizeRollBackups value="10" />
<maximumFileSize value="4096KB" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %-5level [%property{ENV}] [%property{UID}] %logger - %message%newline" />
</layout>
</appender>
<appender name="TransportAppender" type="log4net.Appender.RollingFileAppender">
<file value="${TEMP}\logs\client\${ENV}\client.comm.log" />
<appendToFile value="true" />
<rollingStyle value="Size" />
<maxSizeRollBackups value="10" />
<maximumFileSize value="4096KB" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %-5level %logger - %message%newline" />
</layout>
</appender>
<appender name="DetailedTransportLog" type="log4net.Appender.BufferingForwardingAppender">
<threshold value="DEBUG" />
<bufferSize value="200" />
<appender-ref ref="TransportAppender" />
</appender>
<appender name="FileLog" type="log4net.Appender.BufferingForwardingAppender">
<bufferSize value="20" />
<lossy value="false" />
<appender-ref ref="RollingFileAppender" />
</appender>
<appender name="FilteredFileLog" type="log4net.Appender.ForwardingAppender">
<threshold value="WARN" />
<appender-ref ref="FileLog" />
</appender>
<logger name="RefreshDataService" >
<level value="DEBUG" />
<appender-ref ref="FilteredFileLog" />
<appender-ref ref="DetailedTransportLog" />
</logger>
You can use a level range filter on the appender:
<filter type="log4net.Filter.LevelRangeFilter">
<levelMin value="WARN" />
<levelMax value="FATAL" />
</filter>
<filter type="log4net.Filter.DenyAllFilter" />
My understanding is that the Threshold property is used tell the appender to flush the buffer when messages of a certain level are logged. This way you can make for instance sure that errors are written immediately to the database.
