thanks alot for your reply, but i can not resolve my problem.
>>Monitor Wicket page request using JAMon,
http://blog.xebia.com/2008/02/02/monitor-wicket-page-request-using-jamon/
it only trace the request time, but i mainly want to know why the
application session occupy so many memory.
>>try RequestLogger at first.
i add code in application init method
if(DEVELOPMENT.equalsIgnoreCase(getConfigurationType())){
//Get the logger
IRequestLoggerSettings reqLogger =
Application.get().getRequestLoggerSettings();
//Enable the logger
reqLogger.setRequestLoggerEnabled(true);
/**
* Set the window of all the requests that is kept in memory for
viewing. Default is 2000, You
* can set this to 0 then only Sessions data is recorded (number
of request, total time, latest
* size)
*/
reqLogger.setRequestsWindowSize(3000);
}
and add log4j configure as:
log4j.category.org.apache.wicket.protocol.http.RequestLogger
=debug,reqLogger
log4j.additivity.org.apache.wicket.protocol.http.RequestLogger=false
log4j.appender.reqLogger=org.apache.log4j.RollingFileAppender
log4j.appender.reqLogger.File=D:/517wm_data/logs/wicketRequestLogger.log
log4j.appender.reqLogger.MaxFileSize=10MB
log4j.appender.reqLogger.MaxBackupIndex=10
log4j.appender.reqLogger.layout=org.apache.log4j.PatternLayout
log4j.appender.reqLogger.layout.ConversionPattern=%d %-5p -
%-26.26c{1} - %m\n
here is result:
