log4j

Right now for my ConversionPattern I have: log4j.appender.A1.layout.ConversionPattern=%d{yyyy MMM dd HH:mm:ss,SSS} %5p [%t] (%F:%L) - %m%n What I'd like to do is also include the full package name with the class (%F:%L) but I can't find any config to do so in the docs . I do understand that this will be slower, but it's only for debugging and not when the system will be in production. Maybe I just misunderstand you, but %C will output your class with package. From your referenced docs: %C Used to output the fully qualified class name of the caller issuing the logging request. This conversion

用selenium做自动化测试的时候，需要log进行打印 1.导入jar包，如图： 2.将log配置文件放到src文件夹下，如图： 3.在eclipse对项目进行刷新，然后出现配置文件，如图： 4.查看、配置下配置文件： 1 log4j.rootLogger = info,stdout,D,E 2 3 log4j.appender.stdout = org.apache.log4j.ConsoleAppender 4 log4j.appender.stdout.Target = System.out 5 log4j.appender.stdout.layout = org.apache.log4j.PatternLayout 6 log4j.appender.stdout.layout.ConversionPattern = [%-5p] %d{yyyy-MM-dd HH:mm:ss,SSS} method:%l%n%m%n 7 8 log4j.appender.D = org.apache.log4j.DailyRollingFileAppender 9 log4j.appender.D.File = Log\\log4.log 10 log4j.appender.D.Append = true 11 log4j.appender.D.Threshold = DEBUG 12

I mean, I want the logger name to reflect the source.jsp file, no matter if it is included in another file or compiled to a class or whatever. What's wrong with: Logger logger = Logger.getLogger( "source.jsp" ); You can prepend it with a better non-ambiguous prefix, of course. Actually, something along the lines JSPS.source.jsp is better, as you can set up logging rules for JSPS logger, that would later be applied to all sub-loggers. Having said this, why do you need to log from JSP directly? Pavan Dave Firstly, import the required package i.e. <%@page import="org.apache.log4j.Logger"%> then,

i have an issue, i want to change the logging level of log4j at runtime, i have tried many things with log4j.properties file, i have also tried to written a code which after particular time again reads the properties file and again configure the logger. but the problem is, i want to change the logging level to DEBUG for one API call, and then when that call is completed, the logger should again change to the previous value.. please help.. Calling the Logger.setLevel method with the desired Level can alter a Logger 's output level at runtime. The following is an example which demonstrates its

How do I override the default log4j.properties in hadoop? If I set the hadoop.root.logger=WARN,console, it doesnot print the logs on the console, whereas what I want is that it shouldn't print the INFO in the logs file. I added a log4j.properties file in my jar, but I am unable to override the default one. In short, I want the log file to print only the errors and warnings. # Define some default values that can be overridden by system properties hadoop.root.logger=INFO,console hadoop.log.dir=. hadoop.log.file=hadoop.log # # Job Summary Appender # # Use following logger to send summary to

This question already has answers here : Is there a need to do a if(log.isDebugEnabled()) { … } check? [duplicate] (5 answers) When I was going through some code, I noticed the use of logger as follows, if(logger.isDebugEnabled()) logger.debug("Something.."); But in some codes, I observed like this. logger.debug("Something.."); When I looked at the source of log4j, in the debug() method of Logger itself if(logger.isDebugEnabled()) was checked. Then why do we need this unnecessary overhead if(logger.isDebugEnabled()) ?? It's useful when the String your passing to logger.debug(...) takes time to

I'm experimenting writing a java SE swing application using JBoss weld. Weld configures logging with log4j using the following log4j.xml file in the jar: <?xml version="1.0" encoding="UTF-8"?><!DOCTYPE log4j:configuration SYSTEM "log4j.dtd"> <!-- JBoss, Home of Professional Open Source Copyright 2009, Red Hat, Inc. and/or its affiliates, and individual contributors by the @authors tag.

I'm running a testcase (junit) and would like to set the log level to trace so that I can see if all the values are correct. Classes that use logging in the project contain a line like the following: private static final Log LOG = LogFactory.getLog(MatchTaskTest.class); and use a like like this to do the actual debugging LOG.trace("value"); I have never used log4j before, does anybody know how I can change the log level just for the testcase, preferably simply by defining a parameter in
