Logs targeting Excel Pivot Tables
by Thorbjørn Ravn Andersen 11 Apr '13

11 Apr '13

Hi. I want to create a log file which is not directly intended to be readable by humans but to use with Pivot Tables in Excel to generate reports (e.g. over http requests and their duration spread over the day for several months, that kind of thing). I was wondering what the best approach for doing that would be. My guess would be a tab-separated file (to allow Excel to read it in as a CSV-file), with the first field being the timestamp in an Excel compatible form (e.g. a number formatted as a timestamp), and the remaining fields the individual items I need to analyze. (This is what I generate right now using ad-hoc Perl) (We can calculate on that 99.99% of the time that the application will exit with System.exit(0) in my main method, so it is not super important with having a solution robust against e.g. OutOfMemoryError, but I would like one that does not build a large data structure in memory like using JExcel to generate a spread sheet on the fly). Anyone who has experimented with this and have experiences to share? Thanks /Thorbjørn

Hi all, I am using logback in a webapplication and logs work fine. However i also have another timer task started on application start up. logs from this timer task are getting displayed correctly on console using ConsoleAppender, however they do not appear in my rolling file sift appender (other logs from my webapplication are logged fine). Can anyone suggest what could be the problem? -- Happy Coding, Sumit

logback 1.0.9 slf4j 1.7.3 In code : package com.mycomp.xx .... log.debug("Hi there"); in logback.xml <logger name="com.mycomp.xx" level="DEBUG" /> I can see the in the log, that when I make a change to logback.xml... ( scanned every 30 seconds ) .. INFO in ch.qos.logback.classic.joran.action.LoggerAction - Setting level of logger [com.mycomp.xx] to DEBUG But when executing the code, the log "Hi there" is not in the console or the logfile. If I set this.. <root level="DEBUG"> <appender-ref ref="CONSOLE"/> <appender-ref ref="FILE"/> </root> everything is logged... -- Med venlig hilsen / Best regards Kristian Lind

Problem with Groovy detection in Glassfish 3.1.2.2
by Karl Spies 08 Apr '13

08 Apr '13

Hi, my goal is to use slf4j and logback in our Glassfish servers. But I came a cross with an error in the groovy detection. Please see the stacktrace below. I think the problem has something to do with the classloader in glassfish. The libraries are placed in the root lib/endorsed folder. I need them there to have the highest priority while classloading. Is this a problem with my setup and idea, or do I encountered a real misbehavior. I attached a patch within this mail. Thanks in advance.

[Sifting Appender ] Programmatically
by M. MychaL 04 Apr '13

04 Apr '13

Hello, i have created a new configuration with some logger but without appender. I would like to create appender programmatically, to add them to their logger. And finally use MDC context to set which appender will log the messages... For moment, i have create FileAppender, Pattern & Encoder, Filter, Discriminator. I would like to link the FileAppender to SifitingAppender. How to do that ? there is no setparent or set*appender methods.... Any idea ? Thanks.

SLF4J 1.7.5 with LogBack
by Frederic Conrotte 26 Mar '13

26 Mar '13

Hello Regarding performance improvement in SLF4J 1.7.5, as I do not see any LogBackLoggerFactory in the commits: https://github.com/qos-ch/slf4j/commit/4dc6af1af741d9419c33187 I'm wondering if it's worth upgrading if we use SLF4J + LogBack ?
