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 from the LoggingEvent by extracting it before the log is written. Is this feasible ? -- View this message in context: http://old.nabble.com/Intercepting-LoggingEvent-tp30302884p30302884.html Sent from the Log4j - Users mailing list archive at Nabble.com. - To unsubscribe, e-mail: log4j-user-unsubscr...@logging.apache.org For additional commands, e-mail: log4j-user-h...@logging.apache.org
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 since I am adding the appenders to log4j's Logger and storing it in my own repository there is duplication. All the loggers and appenders are in both repositories. I don't think there is will be a serious performance issue because all the loggers are accessed from my repository only but I want to disable log4j's repository but still use log4j's logger. Does this make sense ? -- View this message in context: http://old.nabble.com/Extending-Logger-tp30018462p30199446.html Sent from the Log4j - Users mailing list archive at Nabble.com. - To unsubscribe, e-mail: log4j-user-unsubscr...@logging.apache.org For additional commands, e-mail: log4j-user-h...@logging.apache.org
RE: Extending Logger
Yes. I am responding to your suggestion. The setup performance is not very important. The runtime performance though is.

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.

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 XML because there are too many log files. 2. I want to use my custom logger/appender and another xml file - not log4j.xml - to associate a logger with a file. I am trying to parse and read the file name from my custom XML file and set it in my custom logger that log4j's repository has. -- View this message in context: http://old.nabble.com/Extending-Logger-tp30018462p30113301.html Sent from the Log4j - Users mailing list archive at Nabble.com. - To unsubscribe, e-mail: log4j-user-unsubscr...@logging.apache.org For additional commands, e-mail: log4j-user-h...@logging.apache.org

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 selectAndConfigure(URL url, String clazz, LoggerRepository

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)) {
return;
}
if (Level.TRACE.isGreaterOrEqual(this.getEffectiveLevel())) {
forcedLog(FQCN, Level.TRACE, message, null);
}
}
Can we extend Logger ?

Log as a template for a report
Hi, We are writing several logs as text files. This is used by the ops. teams but we also want the capability to convert the logs files to reports. These reports could be HTML or PDF and the FreeMarker templating engine can achieve this. So there could be two types of log formats for each log. One is a text file and the other could be XML so that FreeMarker can transform it into HTML or PDF. I have two questions. 1. What is the kind of load added when each log is written in two formats ? I know this involves load testing. 2. Is there a facility in log4j that allows plug points for FreeMarker etc. ? What is the general approach followed to show logs as reports ?

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.
