I have to delete logs older than 2 days. My configuration is
<appender name="RollingFile" type="log4net.Appender.RollingFileAppender">
<file value=".\Logs\abc_" />
<lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
<staticLogFileName value="false" />
<rollingStyle value="Date" />
<datePattern value="yyyy.MM.dd'.log'" />
<appendToFile value="true" />
<maxSizeRollBackups value="2" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="[%property{log4net:HostName}] %date [%thread] [%-5level] %logger -- %message%newline" />
</layout>
</appender>
But this doesnt seem to work. Please help!

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.
<log4net>
<root>
<level value="INFO" />
<appender-ref ref="FileAppender" />
</root>
<appender name="FileAppender" type="log4net.Appender.FileAppender">
<file value="D:\inetpub\wwwroot\COTTProduction\ServiceLogs\COTT.log" />
<appendToFile value="true" />
<rollingStyle value="Date" />
<maxSizeRollBackups value="10" />
<maximumFileSize value="100MB" />
<datePattern value="_yyyyMMdd.log" />
<lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %level %logger - %message%newline" />
</layout>
<filter type="log4net.Filter.LevelRangeFilter">
<levelMin value="INFO" />
<levelMax value="FATAL" />
</filter>
</appender>
</log4net>
Here is my appender:
<appender name="ApplicationRollingFile" type="log4net.Appender.RollingFileAppender">
<file type="log4net.Util.PatternString" value="logs/application.log" />
<appendToFile value="true" />
<rollingStyle value="Composite" />
<preserveLogFileNameExtension value="true"/>
<datePattern value=".yyyy-MM-dd-hhmmss" />
<maxSizeRollBackups value="50" />
<maximumFileSize value="500KB" />
<staticLogFileName value="false" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %level %logger %C.%M --- %message --- %newlineTrace:%newline %stacktrace%newline" />
</layout>
</appender>
What it currently outputs is:
application.time-logging-started.1.log
application.time-logging-started.2.log
application.time-logging-started.3.log
what I want is:
application.time-of-first-rollover.log
application.time-of-second-rollover.log
application.time-of-third-rollover.log
can this be done? if so, how?
It seems your file element is using a PatternString for the file name, the rolling file appender does already use a conversion for name. There is no need to override the default working.
<appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
<lockingModel type="log4net.Appender.FileAppender+MinimalLock"/>
<file value="logs\" />
<datePattern value="yyyy-MM-dd-hhmmss'.log'" />
<staticLogFileName value="false" />
<appendToFile value="true" />
<rollingStyle value="Composite" />
<maxSizeRollBackups value="50" />
<maximumFileSize value="500KB" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline" />
</layout>
</appender>
Similar question to here but slightly different
Like the attached link I am trying to get log4net to output to multiple (x2) files.
As opposed to the link I am looking to have the same information sent to both files. For some reason only the first log file is being generated (Logs.log) and not the second (LogsTest.log)
Can anyone shine some light on this for me please?
<log4net>
<appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
<file value="Logs.log" />
<appendToFile value="true" />
<rollingStyle value="Size" />
<threshold value="INFO" />
<filter type="log4net.Filter.LevelRangeFilter">
<levelMin value="INFO" />
<levelMax value="OFF" />
</filter>
<maxSizeRollBackups value="30" />
<maximumFileSize value="50MB" />
<staticLogFileName value="true" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %-5level %logger %P{url} %P{usr} %P{addr} – %message%newline" />
</layout>
</appender>
<appender name="RollingFileAppender1" type="log4net.Appender.RollingFileAppender">
<file value="LogsTest.log" />
<appendToFile value="true" />
<rollingStyle value="Size" />
<threshold value="INFO" />
<filter type="log4net.Filter.LevelRangeFilter">
<levelMin value="INFO" />
<levelMax value="OFF" />
</filter>
<maxSizeRollBackups value="30" />
<maximumFileSize value="50MB" />
<staticLogFileName value="true" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %-5level %logger %P{url} %P{usr} %P{addr} – %message%newline" />
</layout>
</appender>
<logger name="PlaceGen">
<level value="ALL" />
<appender-ref ref="RollingFileAppender" />
<appender-ref ref="RollingFileAppender1" />
</logger>
</log4net>
Would have been smart to have the local operator to restart the application first
I want my logfile to end up like this :
2015-04-23.log (YYMMDD.log)
<root>
<level value="DEBUG" />
<appender-ref ref="RollingFileAppender" />
</root>
<appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
<file type="log4net.Util.PatternString" value="logs\CTI\ServiceName" />
<appendToFile value="true" />
<rollingStyle value="Date" />
<maxSizeRollBackups value="10" />
<maximumFileSize value="20MB" />
<staticLogFileName value="false" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %level %logger - %message%newline%exception" />
</layout>
</appender>
After running the code, the log file comes up as ServiceName_2015-04-23.log.2015-04-23.
What is the issue?
The appender should look like this:
<appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
<file value="logs\CTI\ServiceName\" />
<datePattern value="yyyy-MM-dd'.log'" />
<appendToFile value="true" />
<rollingStyle value="Composite" />
<maxSizeRollBackups value="10" />
<maximumFileSize value="20MB" />
<staticLogFileName value="false" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %level %logger - %message%newline%exception" />
</layout>
</appender>
The key is the datePattern where we add '.log' to the pattern.
Two years later... Better late than never.
You use rollingStyle=date, so log4net adds date in the end of file name.
You can find useful config examples for RollingFileAppender class here.
I used this config but a date is always added to the current file ('log.20130805.0.log').
<appender name="LogFileAppender" type="log4net.Appender.RollingFileAppender">
<file value="Logs/logFile.log" />
<appendToFile value="true" />
<preserveLogFileNameExtension value="true" />
<rollingStyle value="Composite" />
<datePattern value=".yyyyMMdd" />
<maximumFileSize value="10MB" />
<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>
The result of that config is :
log.20130805.0.log
log.20130805.1.log
log.20130805.2.log
log.20130805.3.log
What I get with staticLogFileName = true is :
log.log
log.1.log
log.2.log
log.3.log
What I want is :
log.log
log.20130805.1.log
log.20130805.2.log
log.20130805.3.log
I know I'm late to the party, but I believe I have figured out how to use a composite RollingFileAppender properly. I'm posting it here for posterity, in case anyone stumbles upon this in a search:
<appender name="rollingfileappender" type="log4net.Appender.RollingFileAppender">
<file value="C:\Logs\logfile.log" />
<datePattern value=".yyyyMMdd" />
<preserveLogFileNameExtension value="true" />
<appendToFile value="true" />
<rollingStyle value="Composite" />
<maxSizeRollBackups value="10" />
<maximumFileSize value="100Kb" />
<staticLogFileName value="true" />
<layout type="log4net.Layout.DynamicPatternLayout">
<conversionPattern value="%[level] - %date - %message" />
</layout>
</appender>
The key here is:
<preserveLogFileNameExtension value="true" />
and
<staticLogFileName value="true" />
When your current log files are being appended, you'll see:
logfile.log
logfile.1.log
logfile.2.log
etc...
Once the new day hits, those should be renamed to:
logfile.20200623.log
logfile.20200623.1.log
logfile.20200623.2.log
etc...
and you'll have a new logfile.log, still catching your current logs.
You can use the function below.
This function first gets the file location that you set in web.config and after that you can add any path that you want! (like Date or Customer or...)
WebConfig:
<appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
<file value="C:\\t4\\"/>
<appendToFile value="true"/>
<rollingStyle value="Composite"/>
<datePattern value="_yyyy-MM-dd.lo'g'"/>
<maxSizeRollBackups value="10"/>
<maximumFileSize value="1MB"/>
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date User:%identity IP:%X{addr} Browser: %X{browser} Url: %X{url} [%thread] %-5level %c:%m%n"/>
</layout>
</appender>
Function:
public static void ChangeFileLocation(string _CustomerName,string _Project)
{
XmlConfigurator.Configure();
log4net.Repository.Hierarchy.Hierarchy h =(log4net.Repository.Hierarchy.Hierarchy)LogManager.GetRepository();
foreach (IAppender a in h.Root.Appenders)
{
if (a is FileAppender)
{
FileAppender fa = (FileAppender)a;
string sNowDate= DateTime.Now.ToLongDateString();
// Programmatically set this to the desired location here
string FileLocationinWebConfig = fa.File;
string logFileLocation = FileLocationinWebConfig + _Project + "\\" + CustomerName + "\\" + sNowDate + ".log";
fa.File = logFileLocation;
fa.ActivateOptions();
break;
}
}
}
and result is like this: C:\t4\TestProject\Customer1\Saturday, August 31, 2013.log
Based on these tips I guess it isn't possible, unfortunately (with the current implementation of RollingFileAppender):
