Our log4net (config below) gives us the Exception.Message, but that's all. I need it to log the stack trace and all inner exceptions, with the stack trace for each of those.
How do I do this?
<log4net>
<appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
<param name="File" value="C:/temp/AutoTag_Word.log"/>
<param name="AppendToFile" value="true"/>
<param name="MaxSizeRollBackups" value="10"/>
<param name="MaximumFileSize" value="1000KB"/>
<param name="RollingStyle" value="Size"/>
<param name="StaticLogFileName" value="true"/>
<layout type="log4net.Layout.PatternLayout">
<param name="ConversionPattern" value="%d [%t] ac.server %-5p %c - %m%n%exception"/>
</layout>
</appender>
<root>
<level value="DEBUG"/>
<appender-ref ref="RollingFileAppender"/>
</root>
<logger name="WindwardArrow.net.windward.arrow.datasource.ado">
<level value="DEBUG"/>
</logger>
</log4net>
This works:
Add our custom log formatter.
Use the below:
<log4net debug="false">
<appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
<param name="File" value="C:\temp\CleanTemplates.log" />
<param name="AppendToFile" value="true" />
<param name="MaxSizeRollBackups" value="2" />
<param name="MaximumFileSize" value="50KB" />
<param name="RollingStyle" value="Size" />
<param name="StaticLogFileName" value="true" />
<layout type="Kailua.net.windward.utils.ExceptionFormatter">
<param name="ConversionPattern" value="%date [%thread] %level %logger - %message%newline%exception" />
</layout>
</appender>
<root>
<level value="debug" />
<appender-ref ref="RollingFileAppender" />
</root>
</log4net>

I am using log4j RollingFileAppender to roll the log files based on file size. The max file size we have set is "10 MB". It works fine in tomcat 6 but when we migrate to TomEE Plus.. the log files rolling not happening..the file size keep on growing.
log4j configuration is below:

I had resolved this issue by separating the log4j.xml into two separate configurations. that solved my problem.
i have a log4j.xml and a scala file. I use slf4j.
this is the xml file
<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/">

but when I log an error as
logger.error("Error")
that error goes to error.log file. But it also goes to info.log file. can someone help me to get this thing correct.
I use this following configuration and able to see the log messages in separate log files
<?xml version="1.0" encoding="UTF-8" ?>

This is how I am using the logger
import org.apache.log4j.Logger;
public class TestLogger {
private static Logger debugLog = Logger.getLogger("debug");
private static Logger infoLog = Logger.getLogger("info");
private static Logger errorLog = Logger.getLogger("error");
public static void main(String[] args) {
debugLog.debug("Debug message");
infoLog.info("Info message");
errorLog.error("Error message");
}
}
I have the following layout patter in my log4j xml file:
"%d{ISO8601} %c %p [%t] [%x] 9.5.4.RC12 %m%n"
What I want is that when ever I get a log containing message process [proc#] completed, it should be skipped. I mean every log except the one containing this message should be printed. [proc#] will contain the process number of max lenght 4.
What can I desing a filter with this function in my xml config file. If so, then how?
ExpressionFilter can do that.
In a filter definition inside an appender definition, use an expression similar to (note LIKE is the regex match operator):
"MSG LIKE 'process \[.*\] completed'"
See ExpressionFilter javadoc here:
http://logging.apache.org/log4j/companions/apidocs/org/apache/log4j/filter/ExpressionFilter.html
Example:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">
<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/" debug="false">

<param name="ConversionPattern" value="%d %p [%c] - %m%n"/>
</layout>
<filter class="org.apache.log4j.filter.ExpressionFilter">

Example taken from here: http://blog.trifork.com/2011/08/23/filtering-specific-exceptions-when-using-log4j/
This is how I've configured log4j to filter out by IP address. In particular 127.0.0.1 as illustrated in log4j.xml below. Note, you must also include log4j.dtd alongside log4j.xml. You must use the XML syntax.

I need only Info message present in program code should be printed in log file . But while executing the program it is printing all the message (debug, info , warn). How do i do that?
Try to use this element instead of Threshold parameter under appender element:
<filter class="org.apache.log4j.varia.LevelRangeFilter">
<param name="LevelMin" value="INFO"/>
<param name="LevelMax" value="OFF"/>
</filter>
