jul-to-slf4j conflicts with logback-classic
by cowwoc 24 Oct '08

24 Oct '08

Hi, If I deploy: slf4j-api logback-classic logback-core jul-to-slf4j I get: Deploying application in domain failed; Logging factory implementation cannot be null. See also http://www.slf4j.org/codes.html#null_LF but if I remove jul-to-slf4j from the classpath it works just fine (except, obviously, jul-to-slf4j is disabled). I am invoking SLF4JBridgeHandler.install() from within a ServletContextListener. Perhaps this is too late somehow? What am I doing wrong? Thank you, Gili -- View this message in context: http://www.nabble.com/jul-to-slf4j-conflicts-with-logback-classic-tp1959092… Sent from the Logback User mailing list archive at Nabble.com.

Hostname in SMTPAppender subject
by Mayes, Christopher 30 Sep '08

30 Sep '08

Hi, there. Is there a way to get the reporting machine's hostname into the subject of the SMTPAppender's email address? According to a blog post, (http://blog.spiralarm.com/richard/2007/10/watching-production-logs.html) you can do something like this for log4j: <param name="Subject" value="[SMTPAppender] ${user.name}@${hostname} error message" /> Is there a Logback equivalent? Thanks, -Chris

Using two separate logback configurations in same app
by Silvano Maffeis 26 Sep '08

26 Sep '08

Hi, My application holds an already initialized slf4j/logback environment. Now at some point in my code I would like to create a logback Logger using a completely different configuration, without inheriting any configuration settings from the logback environment already defined in my app (which was done via logback.xml on the classpath), and also without interfering with the previously created loggers either. I thought the most natural way would be to create my LoggerFactory instance, configure it, and then to create a Logger from there. But that seems not the way how its done in logback. Is what I want possible at all? If yes, how? Thanks! Silvano

Number of logs
by Greg Flex 25 Sep '08

25 Sep '08

Hi all, I'm running some benchmarking and I've noticed that when calling logger.xxx in a loop (10,000 iterations) only about 3964 are written. I'm testing this with both MySQL and HSQLDB databases. Can someone please let me know what's seems to be a problem? Do I need to configure this in some config file? How many times I can write at once to a database? Thanks

JmxConfigurator not being exposed in Weblogic
by Michael Sell 20 Sep '08

20 Sep '08

Has anyone confirmed that the JmxConfigurator is working as-is under Weblogic 9 or 10? I recently moved our application over to using Logback, and the logging is working wonderfully. However, adding the <jmxConfigurator /> tag to my logback.xml doesn't seem to be working. All of the other MBeans that my application exposes are there, but logbacks bean never gets exposed. I have the logback debugging on, but there isn't even any output about the jmx, just the output I always had about adding the appenders and such. Can I get some suggestions on what I am doing wrong, or how I can go about getting logback to tell me what is going wrong with exposing the MBean? Thanks for the help, and cheers on the great product. -Michael

RollingFileAppender that splits logs into files/directories by logger name
by Eric Faden 18 Sep '08

18 Sep '08

I am building a RollingFileAppender to split the logs into directories/files based on the logger name. The goal is to have a single Appender "A" that takes in a bunch of loggers and spits the logs out into separate RollingFileAppenders based on the logger name. Basically my plan is to have an Appender that contains a HashMap of LoggerName (String) to RollingFileAppender. When I see a name for the first time I create a RollingFileAppender for it and place it into the HashSet. My problem is that there is going to be a single RollingPolicy/Triggering Policy for "A" which needs to get duplicated to the subappenders. The issue with this is that I can't use the same object since i need to modify the filepattern to have the correct file names on it. The problem with that is that the object isn't cloneable. Can anyone think of a good way to handle this? Or am I going about this all wrong? -Eric

Method Tracing in LogBack?
by Kimberly Vogt 17 Sep '08

17 Sep '08

Hi Again, Has anyone had any experience trying to do method tracing with LogBack? We are looking into using something like this: http://x-15.org/tracing.htm , or some other package, and have it write its results into LogBack. Thanks, Kim
