If there is support for this idea, it can be implemented with relative ease. The log4j version can be called 1.3, 1.4 or even 2.0. The difficult part is reaching agreement among the log4j committers. I think if log4j implemented SLF4J, this would have a very positive unifying effect on logging in the Java world. Obviously, I am willing to do the work. As you are probably aware, more and more projects are adopting the SLF4J API. I would venture say that SLF4J's adoption rate is roughly equivalent to that of log4j itself. Recently, Jspwiki decided to adopt the SLF4J API for its logging. See https://issues.apache.org/jira/browse/JSPWIKI-376 Harry Metske synthesized various logging paths in JSPWiki https://issues.apache.org/jira/secure/attachment/

Hello, I am using the SMTPAppender to send mails in case of errors. I have a requirement to have the number of error emails limited to e.g. 10 per minute. Is this possible with any of the standard filters? cheers, dirk

log4j ignoring log4j.properties and only showing INFO messages

Farrukh Najmi — 2008-11-26T21:54:45

I have been using log4j 1.2.14 and commons-logging 1.1 in my project successfully for a long time. All of a sudden I am finding that my log4j.properties file can no longer control logging behavior for log4j. The only messages that are logged are INFO messages. Since my project is a maven project with many direct and indirect dependencies its possible that one of those dependencies changed in some way to change my apps logging behavior. I have tried specifying my log4j file explicitly using system property: -Dlog4j.configuration=file:///somedir/log4j.properties No joy with that. Expected trace messages till did not appear. Then I wondered perhaps the problem is in commons-logging so I tried to turn diagnostic on in common-logging using system property: -Dorg.apache.commons.logging.diagnostics.dest=somefile.txt Still no joy. No file was created. What could be wrong and how can I debug this further? Thanks for your help.

calling logger from one location (method)

Andy Rozman — 2008-11-26T18:06:47

Hi ! I have one weird request... I would like to call log from one certain method. Problem is that I need logging output to be sent to my gui as well as into log file (some logs not all), so I wanted to create method that would call logger... something like this: public void writeLog(int type, String msg) { // some my code if (type==DEBUG) { log.debug(msg); } // some more code and if conditions } Problem is that whenevr I write to log through this method I get as source this method. Would it be possible to make so, that logger writes as source originating method. Thank you for all answers... Andy

AW: [SPAM (Bayesain Analysis)] - Repository selectors, useful? - Bayesian Filter detected spam

Bender Heri — 2008-11-26T15:06:27

Hallo Ceki I found log4j's RepositorySelector very useful, I think I would not have been able to solved my problem without it. I use it in a System which is designed to maintain different customers. A single customer should never see any data (or even know about the existence) of other customers. So I needed to separate also all logs. One core application is a scheduler app which maintains different jobs which run at regular intervals (configured for each customer and job kind). The jobs make heavy use of common libraries (in fact most of the work is done within these libraries, which make a lot of log outputs). This log outputs should never mix between customers and jobs. Such a job is running in its own thread. Therefore I can use the MDC which is feeded at every thread start with infos about the current job and the current customer. This info is then used by the repository selector for choosing the correct repository (where file appenders are defined with filenames and storage locations mirroring these

Repository selectors, useful?

Ceki Gulcu — 2008-11-26T13:06:49

Hello, I am in the process of fixing bugs related to context selectors in logback. Context selectors are the equivalent of repository selectors in log4j. However, while few years back I thought that context selectors, aka repository selectors, were the wave of the future, I am increasingly skeptical about their usefulness. If you are using context/repository selectors, could you please explain why?

What is the simpliest way to add hostname into Subject in SMTP appender?

Vitaly — 2008-11-25T11:27:31

I'm looking for a way to add hostname into emails which SMTP appender sends. I prefer do not modify log4j.xml on every server, but use some macro for it. Is it doable? TIA, Vitaly

Is that possible to split values from (%m) message object in log4j.properties file

manish_goyal — 2008-11-25T10:32:26

Hi, I am using log4j.properties file to log data into database. I am setting multiple values in a JAVA file using different Logger.info(“value”). In log4j.properties file, when I am using %m to insert values in database, it’s inserting all values in a single column. I want to put values from %m into different column. Is there any way to split values into different column? Is this possible? Any pointers would be greatly appreciated. Thanks. Regards, Manish

Can we define multiple Logger instance in a single class file?

manish_goyal — 2008-11-23T13:25:11

Hi, Could any one tell me how to create multiple Logger instance in a single class? Is this possible? If it is possible then what will be the value for "?". Logger myLogger = Logger.getLogger("?"); in class file. and for referring the same Logger instance in log4j.properties file, how we will be defining the Appender. I don't want to use rootLogger . Please respond me as soon as possible. Thanks. Regards, Manish

How to log ip addresses?

Poythress, Lynn — 2008-11-20T22:55:37

Hi, We are running Unicon's uPortal product. It utilizes log4j and we have a log4j.properties file which creates a portal.log file. In that portal.log file it logs users that log on to the portal. We would like it to log the ip address of each user; currently it just shows user name and userid. Do we modify the log4j.properties file to have it add each user's ip address to the log? If so, can you point me in the right direction? I read about appenders, but couldn't see any parameters that would specifically capture ip addresses. Thanks, Lynn Poythress

Rolling logs to custom folder

André Lopes — 2008-11-19T13:48:37

Hi all, I'm trying to find some configuration/appender that as the capability to roll log files to a custom folder. I have searched on google and on the log4j mailing lists but i haven't find any information on this issue. If someone could point me any reference/link/appender to resolve this problem it would save me a lot of time. Cheers, André Lopes

Problems with rollover of RollingFileAppender - data loss

2008-11-16T22:47:17

Hi, I'm running log4j-1.2.15 and have a problem that I'd like to put forward to see if anyone has a solution. I have an application that is very short lived but is run many times. It's invoked by an external scheduling and orchestration application that can only run the application by constructing a fresh JVM via JNI every time it wants to run it. The application logs using log4j and its RollingFileAppender with append=true. The problem that I have encountered is that I have observed that sometimes the log files are getting partially wiped. I am putting this down to the fact that the JVM might be shutting down whilst the rolling activity is taking place - resulting in partially rolled files. I have tried adding a shutdown hook to invoke LogManager.shutdown() with the hope that this would block until the appenders had finished doing their work before the JVM shutdown but this doesn't appear to work. I was able to replicate this by invoking the application many times continually. It doesn't happen ofte

problem with JDBC logging
