If I have a config file which says:
log4j.rootCategory=DEBUG, file
log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.MaxBackupIndex=2
log4j.appender.file.MaxFileSize=100KB
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{dd MMM HH:mm} %-5p %c %x - %m%n
log4j.appender.file.File=log4j.log
log4j.appender.file.Threshold=DEBUG
Then the file appender logs at log level DEBUG.
I converted this to code:-
RollingFileAppender fa;
Category root = Category.getRoot();
root.setPriority(Priority.DEBUG);
PatternLayout pl=new PatternLayout("%d{dd MMM HH:mm} %-5p %c %x - %m%n");
try
{
fa = new RollingFileAppender(pl, "log4j.log", true);
}
catch(java.io.IOException e)
{
System.err.println("Unable to create logfile");
return;
}
fa.setMaxFileSize("100KB");
fa.setMaxBackupIndex(2);
fa.setThreshold(Priority.DEBUG);
In a previous message, Ceki Gülcü said that doing the fa.setThreshold actually
excludes the DEBUG messages.
My aim is to have (in my own config file) a parameter allowing the user to change the
logging level.
So how can the user set the logging level to DEBUG if setting it to DEBUG excludes
DEBUG messages ?
Have I mis-understood something here ?
