Re: [SCL-4] Intercepting LoggingEvent

@Heri Do you think this could affect performance ? @Scott It looks like this is not part of 1.2.16 or extras. Git has the code though. -- View this message in context: http://old.nabble.com/Intercepting-LoggingEvent-tp30302884p30308920.html Sent from the Log4j - Users mailing list archive at

Intercepting LoggingEvent

I am trying to intercept the LoggingEvent which is an instance of a custom LoggingEvent created by a library. I have a custom appender and also a filter but neither seems to be a clean way of extracting specific custom information for logging. I think there should be a way to log only what I want

Re: Extending Logger

I think I have done what was suggested but there is a catch. I decided to go for a parallel log4j repository for more manageability but retained the log4j Logger. I didn't extend it or wrap it. ( e.g ) JBoss uses its own repository to take care of multiple web applications. The problem is that s

RE: Extending Logger

Yes. I am responding to your suggestion. The setup performance is not very important. The runtime performance though is. If I setup everything programmatically log4j.xml is not at all needed ? -- View this message in context: http://old.nabble.com/Extending-Logger-tp30018462p30113852.html Sent

RE: Extending Logger

So this is what I understand. If I have too many appender sections in the XML then one appender for a logger is created by log4j. Instead of that I can have one appender and a custom logger for each log file. Both could be equivalent as far as performance is concerned. Am I right ? -- View th

RE: Extending Logger

I wanted to associate the logger file with each Logger instead of the Appender. I have a setFile/getFile in the Logger that I plan to call using my custom Appender so that the log message is written to the file associated with the Logger. Reasons : 1. We have two many appender sections in the XM

I don't have a way to put my custom logger in the log4j repository so that it is used in place of the log4j Logger. -- View this message in context: http://old.nabble.com/Extending-Logger-tp30018462p3044.html Sent from the Log4j - Users mailing list archive at Nabble.com. -

Re: Extending Logger

I have wrapped log4j's Logger in a 'custom' logger. The custom logger is my logger. The FQCN of my logger is set in the 'logger' element in the XML. I have an extra parameter to set in my logger that is not in Log4j's logger. So I think that I have to configure this when log4j calls void selec

Since extension of Logger is discouraged I wrap it. I think the configuration can be set like this. Thanks, Mohan -- View this message in context: http://old.nabble.com/Extending-Logger-tp30018462p30085722.html Sent from the Log4j - Users mailing list archive at Nabble.com. -

Re: Extending Logger

Solved this. Is there a way to get my custom logger that log4J has configured and set some values using reflection ? The API does not seem to return the correct type. It returns Logger always and not CustomLogger. -- View this message in context: http://old.nabble.com/Extending-Logger-tp300184

Extending Logger

The complete Log4J manual discourages us from extending Logger but we use the recommended pattern then 'repository' and 'getEffectiveLevel()' are inaccessible because they are protected in Category. public void trace(Object message) { if (repository.isDisabled(Level.TRACE_INT)) {

Re: [SCL-2] Re: Multiple log files, multiple logger names and the same appender

Jacob, What you are suggesting can be done using the XML itself ? I think this new appender is required due to the limitation in associating an individual logger with its own file. Thanks, Mohan -- View this message in context: http://old.nabble.com/Multiple-log-files%2C-multiple-logger-name

Re: [SCL-2] Re: Multiple log files, multiple logger names and the same appender

My initial idea is to pass multiple file names in the XML in the appender section and maintain a list in the custome appender Java code and then based on the logger name or some other parameter pick the correct file name. Performance is one of our major concerns. -- View this message in context:

Ok. Will try. I think you mean that in order to associate a file name with each logger in the hierarchy instead of the appender I need to write a custom appender. Am I on the right track then ? -- View this message in context: http://old.nabble.com/Multiple-log-files%2C-multiple-logger-names-a

RE: RollingFileAppender not working consistently

TimeBasedRollingPolicy seems to be the solution. Correct me if I am wrong. Extract from the doc. During November 23rd, 2004, logging output will go to * the file /wombat/foo.2004-11-23. At midnight and for * the rest of the 24th, logging output will be directed to * /wombat/

RE: RollingFileAppender not working consistently

I have looked at the source here and I have a question. Since the log4j extras has other methods of rolling over that are time based I thought if we schedule the rename for a lean period when there is not much log file updates then there would be no problem. Am I on the right track ? What about
