Hi there,
I am working on server which used thread pool to process each client request
by separate dedicated thread.
My intention is each thread ( of thread pool ) should have its own logger
and hence all client processed by that thread must be logged in
corresponding thread specific logger, that is I wanted to maintain logger
object as much as threads present.
My problem is that logger merging log content with other logger content, for
example sometime logger for thread 5 wirtes log in file for thread 8 and so
on .....
I am creating and configuring logger at run time using code specified as
below.
Is there any thing I am missing in code ????
I am using log4j-1.2.8 on windows and java's executor server for thread
pooling.
My server having 64 threads ( ie 64 logger ) and it is running on "8 core"
machine, is this a problem as it is hightly multithreaded ????
I confirm that server creates exactly 64 logger but its containts are
interfering with different logger file.
code variables:
sLoggerName : Current thread name ( Thread.currentThread.getName() )
m_sFilePath : log file path
m_sExt : log file extention
m_layout : static layout object
............................................................... Code
.................................................
public static final Logger getLogger( final String sLoggerName )throws
IOException
{
final Logger logger = LogManager.exists(sLoggerName);
if(logger != null)
{
return logger;
}
Logger newLogger = LogManager.getLogger(sLoggerName);
//Logger is not exists so create appender for logger
String sFileName = m_sFilePath + sLoggerName + m_sExt;
RollingFileAppender appender = new RollingFileAppender(m_layout,
sFileName, true );
appender.setMaxBackupIndex( m_iMaxBufferIndex );
appender.setMaxFileSize( m_sLogMaxFileSize );
newLogger.addAppender( appender );
newLogger.setLevel( m_logLevel );
newLogger.setAdditivity(false);
return newLogger;
}
.....................................................log4j.property ( for
root logger )................................................
# Category Configuration
log4j.rootLogger=INFO,Konsole,Roll
# Console Appender Configuration
log4j.appender.Konsole=org.apache.log4j.ConsoleAppender
log4j.appender.Konsole.layout=org.apache.log4j.PatternLayout
# Date Format based on ISO*8601 : %d
log4j.appender.Konsole.layout.ConversionPattern=%d [%t] %5p %c * %m%n
# Roll Appender Configuration

log4j.appender.Roll.MaxFileSize=100MB
log4j.appender.Roll.MaxBackupIndex=10

# Date Format based on ISO*8601 : %d
log4j.appender.Roll.layout.ConversionPattern=%d [%t] %p (%F:%L) * %m%n

your help will makes me happy.
