Filename in log4net

Wed, 25 Nov 2009 04:43:06 -0800

Hi All,
i am doing a VB.NET windows application. In that i am using Log4Net for logging details. I am new to using Log4Net. The problem i am facing is i want to create the logfiles with same name each day. means today if a log file is created with name debug.log, tomorrow also it should create a new log file with same name with out any change in the previous file name. how can i do this ? My appender configuration looks like this ..

<appender name="RSLogFileAppenderDebug" type="log4net.Appender.RollingFileAppender">
<file value="C:\Log4NetExamples\debug.log" />
<appendToFile value="true" />
<rollingStyle value="Date" />
<filter type="log4net.Filter.LevelRangeFilter">
<acceptOnMatch value="true" />
<levelMin value="DEBUG" />
<levelMax value="FATAL" />
</filter>
<maxSizeRollBackups value="1" />
<maximumFileSize value="10MB" />
<staticLogFileName value="true" />
<lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%newline%date [%thread] %-5level - %message" />
</layout>
</appender>

<appender name="RSLogFileAppenderFatal" type="log4net.Appender.RollingFileAppender">
<file value="C:\Log4NetExamples\Fatal.log" />
<appendToFile value="true" />
<rollingStyle value="Date" />
<filter type="log4net.Filter.LevelRangeFilter">
<acceptOnMatch value="true" />
<levelMin value="FATAL" />
<levelMax value="FATAL" />
</filter>
<maxSizeRollBackups value="1" />
<maximumFileSize value="10MB" />
<staticLogFileName value="true" />
<lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%newline%date [%thread] %-5level - %message" />
</layout>
</appender>

<root>
<level value="ALL" />
<appender-ref ref="RSLogFileAppenderDebug" />
<appender-ref ref="RSLogFileAppenderFatal" />
</root>

How can i do this ?? do i need to make any change in the appender config ? can anybody help?

I don't know anything about the software you are using... I did how ever read a few things just now and here is a suggestion (don't know if this will help or not)...

Based on what I read (here: http://logging.apache.org/log4net/release/config-examples.html) you should be able to specify Environment Variables in the filename of the Log File... There is NO WAY to have 2 files with the SAME NAME in the SAME LOCATION, so if you want to have a new file each day, you have to create a file with a new name... Based on what I read on Logging.apache.org, you should be able to specify a dynamic filename, but how this acts I couldn't tell you since I have never used this before...

here goes:

'First you want to set the Enviroment Variable when you load your software
System.Environment.SetEnvironmentVariable("log4net
File", "log-" & Format(Now.ToString, "MM-dd-yyyy") & ".txt")

Now that your environment var is set, you can use that $(log4netFile) environment variable in the FileName of the log4net settings in app.config.

Hope this atleast gets you moving down a path towards solving your question

I know its a pretty dead thread... but I suspect the issue is from using <appender name="RSLogFileAppenderDebug" type="log4net.Appender.RollingFileAppender">
when you want to be using

<appender name="RSLogFileAppenderDebug" type="log4net.Appender.LogFileAppender">
