Logfiles containing 'java' as methodname for %M instead of real method name

Thomas Wiedmann — 2008-09-06T14:11:40

Hello, in the ...layout.ConversionPattern of a DailyRollingFileAppender the %M parameter is defined to output the name of the method where the logging was triggered. In some logfiles instead of the real method name the entry 'java' is found. What may be the reason for this behaviour and how to achieve the output of the name of the triggering method?

CLOB datatype column usage with JDBCPlus jdbc appender

Vaibhav Kumar — 2008-09-04T09:56:58

Hi, I am using JDBCPlus (http://www.dankomannhaupt.de/projects/index.html) as a jdbc appender for logging into database. For a requirement, I had to change the datatype of a column (which stores the message string to be logged) from varchar2(4000) to CLOB. But as soon I do this, the logging in database stops and the stack trace got is : log4j:ERROR JDBCAppender::flush_buffer(), : java.sql.SQLException: Internal Error: Unable to construct a Datum from the specified input at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:168) at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:210) at oracle.jdbc.dbaccess.DBError.check_error(DBError.java:829) at oracle.sql.SQLUtil.makeDatum(SQLUtil.java:645) at oracle.sql.SQLUtil.makeOracleDatum(SQLUtil.java:946) at oracle.jdbc.driver.UpdatableResultSet.updateObject(UpdatableResultSet.java:1568) at oracle.jdbc.driver.OracleResultSet.updateObject(OracleResultSet.java:2787) at org.apache.log4j.jdbcplus.JDBCLogger.append(JDBCLogger.java:742) at org.apache.log4j.jdbcplus.JDBCAppender.flush_buffer(JDBCAppender.java:887) at org.apache.log4j.jdbcplus.JDBCAppender.append(JDBCAppender.java:867) at org.apache.log4j.AppenderSkeleton.doAppend(AppenderSkeleton.java:230) at org.apache.log4j.helpers.AppenderAttachableImpl.appendLoopOnAppenders(AppenderAttachableImpl.java:65) at org.apache.log4j.Category.callAppenders(Category.java:203) at org.apache.log4j.Category.forcedLog(Category.java:388) at org.apache.log4j.Category.log(Category.java:853) at edu.unc.its.util.UNCLogger.prepareAndLogMessage(UNCLogger.java:445) at edu.unc.its.util.UNCLoggerClient.main(UNCLoggerClient.java:23) log4j:ERROR JDBCAppender::flush_buffer(), : java.sql.SQLException: Internal Error: Unable to construct a Datum from the specified input at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:168) at oracle.jdbc.dbaccess.DBError.throwSqlException(DBError.java:210) at oracle.jdbc.dbaccess.DBError.check_error(DBError.java:829) at oracle.sql.SQLUtil.makeDatum(SQLUtil.java:645) at oracle.sql.SQLUtil.makeOracleDatum(SQLUtil.java:946) at oracle.jdbc.driver.UpdatableResultSet.updateObject(UpdatableResultSet.java:1568) at oracle.jdbc.driver.OracleResultSet.updateObject(OracleResultSet.java:2787) at org.apache.log4j.jdbcplus.JDBCLogger.append(JDBCLogger.java:742) at org.apache.log4j.jdbcplus.JDBCAppender.flush_buffer(JDBCAppender.java:887) at org.apache.log4j.jdbcplus.JDBCAppender.append(JDBCAppender.java:867) at org.apache.log4j.AppenderSkeleton.doAppend(AppenderSkeleton.java:230) at org.apache.log4j.helpers.AppenderAttachableImpl.appendLoopOnAppenders(AppenderAttachableImpl.java:65) at org.apache.log4j.Category.callAppenders(Category.java:203) at org.apache.log4j.Category.forcedLog(Category.java:388) at org.apache.log4j.Category.log(Category.java:853) at edu.unc.its.util.UNCLogger.prepareAndLogMessage(UNCLogger.java:445) at edu.unc.its.util.UNCLoggerClient.main(UNCLoggerClient.java:23) 14:39:08,463 FATAL UNC:? - [Message logged at =2008-08-07 10:30:00][Process Id =P1][Process Name =Process1][Transaction Id =T1][Source =Source1][Target =Target1][Service Invoked =LOGGING][Instance Id =I1][Message Id =M1] FATAL - This is the error message.

network logging performance

Paul Smith — 2008-09-04T01:31:23

If anyone out there is using "Logging over the network" of any form (socket, JMS, Multicast, syslog appenders etc), this topic is for you. I'm wondering whether people could comment on their experience setting up high performance logging of application data over the network. The cost of shipping an event over the wire compared with writing it to a local file is obviously higher, and so one can notice user-visible impact if the logging volume is high when using network-based logging (unless one wraps it in AsyncAppenders). Just curious to hear peoples experiences, strategies, and thoughts. Perhaps people can relate to the flow rate they've manage to achieve under different configurations. The driver to my question is that for my Apache Lab project (Pinpoint) I'm building a central logging repository server to allow data mining of the generated logging events. In a high performance site one can have many logging events shipped from multiple threads in, say, a web- app, being shipped serially over the wire, so slowing down the logging can slow down the response time. cheers, Paul Smith

New Appender: PatternFileAppender

David Britton — 2008-09-02T20:38:26

Hello -- I'm not sure if this is the correct way to do this, but my colleague and I have developed a new appender called a PatternFileAppender. I did not see anything else like this in the log4j distribution, but it helped us solve our particular problem, and I think it's a good general purpose appender. If someone knows of another appender like this, I would love to hear about it. I went to make an official patch for log4j 1.2, but I found that the code needed to be compatible with 1.2 source compatibility level. Since the code uses generics in it's use of the LinkedHashMap data structure, it needs 1.5 or later to compile correctly. Anyway, I've attached the file, if there is an "official" way to do this, please point me in the right direction. Here is the high-level details of the appender: * Can process a filename as a pattern, with all substitutions available. (e.g., MDC, date, variable, level, class, ...) * Interesting use cases we are using it for: - Separate log file per "thread" using MDC (note that "thread" could be any separation desired, log level, date, time, etc). * Keeps a cache of the latest 20 open file streams, so as not to overload the OS/filesytem/etc * Adds performance penalty in that each log message will generate an extra pattern lookup. Note that this already happens for the message itself, so this does not seem like a huge impact. Let me know any feedback... Thanks!

DEBUG messages appearing on console?

2008-09-02T19:00:22

I'm trying to configure log4j so that DEBUG messages or lower priority only appear in a log file and not the console, and anything above DEBUG appears on the console. This is what my log4j.properties file looks like right now, however the DEBUG messages are still appearing on the console. I'm using log4j along with Commons Logging API if that makes any difference. # Set the root logger to the INFO level and CA to be it's appender log4j.rootLogger=WARN, CA log4j.appender.CA=org.apache.log4j.ConsoleAppender log4j.appender.CA.layout=org.apache.log4j.PatternLayout log4j.appender.CA.layout.ConversionPattern=%-5p %d{yyyy-MM-dd HH:mm:ss} [%t] %c%n\t{%m}%n%n # LinkHarvester log4j.logger.com.dsn.loadlink=DEBUG, harvester log4j.appender.harvester=org.apache.log4j.RollingFileAppender log4j.appender.harvester.File=C:/log4j/logs/LinkHarvester.log log4j.appender.harvester.MaxFileSize=100KB log4j.appender.harvester.MaxBackupIndex=1 log4j.appender.harvester.layout=org.apache.log4j.PatternLayout log4j.appender.harvester.layout.ConversionPattern=%-5p %d{yyyy-MM-dd HH:mm:ss} [%t] %c%n\t{%m}%n%n (Embedded image moved to file: pic18467.jpg) --------------------------------------------------------------------- To unsubscribe, e-mail: log4j-user-unsubscribe< at >logging.apache.org For additional commands, e-mail: log4j-user-help< at >logging.apache.org

log4j.configuration system property not taken into account?

Gvd — 2008-08-29T12:34:31

Hello, On http://logging.apache.org/log4j/1.2/manual.html I read that the location of the log4j configuration file can be specified by setting the log4j.configuration system property in advance with the path to that file. However, when I start my small test application with the following VM arguments (in eclipse), it seems not to read the log4j file. -Dlog4j.configuration=C:\eclipse\workspace\Log4j128Tester\conf\log4j.xml I have thus everything configured in a log4j.xml file. My log4j.xml file contains the following:

my code is the following: package src; import org.apache.log4j.*; public class MainClass { public static void main(String[] args) { //System.out.println(System.getProperty("log4j.configuration")); Logger lg = Logger.getLogger("Testappender"); System.out.println("start"); lg.debug("test log"); lg.info("test info"); lg.fatal("test fatal"); lg.warn("test warn"); System.out.println("end"); } } Am I missing something or am i doing something wrong? Because I always receive the following error: log4j:WARN No appenders could be found for logger (Testappender). log4j:WARN Please initialize the log4j system properly. Of course, when I put the folder of the log4j.xml in the classpath, it works. But this is not what we want. We want to make it work with the log4j.configuration system property. Any suggestions?

JMS Appender Issue - log4j

NehaG — 2008-08-26T05:05:45

Hi All I am trying to use JMS Appender of log4j in my application using log4j.properties file - but its not running. I am using the jboss-4.2.2.GA Server. The error I am getting is as follows: log4j:WARN No appenders could be found for logger(org.jboss.mq.referenceable.SpyConnectionFactoryObjectFactory). log4j:WARN Please initialize the log4j system properly. The code does not run ahead of this warning and it stucks there. I searched a lot but am not able to find the solution. The log4j.properties file configuration which I am using is as follows: log4j.rootLogger=DEBUG, jmsapp log4j.appender.jmsapp=org.apache.log4j.net.JMSAppender log4j.appender.jmsapp.InitialContextFactoryName=org.jnp.interfaces.NamingContextFactory log4j.appender.jmsapp.ProviderURL=jnp://localhost:1099 log4j.appender.jmsapp.TopicBindingName=topic/testTopic log4j.appender.jmsapp.TopicConnectionFactoryBindingName=ConnectionFactory If someone knows about the problem - please let me know. Any help is a welcome. Thanks Neha

which config file

Reza Razavipour — 2008-08-26T00:58:18

All, how can I programmatically determine the URL to the xml file that my app has configured itself based on? What I am trying to do is to get the URL, load it into a DOMConfigurator so I can determine the specifics of an appender. Is there a better way? Thanks Reza

Multiple Appenders additivity

Omer Dogan — 2008-08-22T07:18:09

When i was trying to log on console with additivity, i realise log4j dont care if parent categories have appropriate level to log the event. is this a design choice and are there any other way to prevent the appenders from logging smaller level of logging events. Best of i can do is changing the source-code of log4j Scenerio I want to write all aplication logs to a file and I want to write only error logs to console and I dont want repeated log statements like "consolelogger.error("error 1"); filelogger.error("error 1")" --- my log4j configutration --- log4j.rootLogger=ERROR,consol log4j.logger.consol =ERROR,consol log4j.appender.consol =org.apache.log4j.ConsoleAppender log4j.additivity.consol =true ... log4j.logger.Application =DEBUG,Application log4j.appender.Application =org.apache.log4j.DailyRollingFileAppender log4j.additivity.Application =true ... --- Code logger.info("log 1 - LEVEL_INFO") logger.error("log 2 - LEVEL_ERROR") ... while i have expecting , with the code above, log file would contains "log 1" and "log 2" console would contains only "log 2 " instead i have got the console and log file contains both "log 1" and "log 2 " info then i check the source code and i found the problem on callAppenders() method and change the beheavior of the method.

log settings an administrator's job?

Paul Pepper — 2008-08-20T12:45:55

Placing log4j settings in the log4j.properties (or log4j.xml) file under WEB-INFO/classes effectively requires the developer to configure logging - e.g. unexploded war files. Shouldn't it be the job of the system admin who deploys the application to configure things like log file location? Or have I missed something? I would like to give the system admin the ability to set the location of the log4j log file in my applications (as with access log info when a sys admin can use org.apache.catalina.valves.AccessLogValve in Tomcat's server.xml). The server.xml (or context.xml) seems like the right place to set the location of the log4j log file - maybe as a JNDI string resource. Can anyone suggest a way of giving system administrators the means of setting log4j configuration settings? Or, can anyone explain why this would be a bad idea? Thanks, Paul.

Can custom appender override the log4j.xml configuration

Aneez Backer — 2008-08-19T04:58:22

Hi I am writing a custom JDBC appender for log4j for my application. I want this custom appender NOT to be affected in any way by the loggign levels / appenders in the application log4j.xml file. The custom Logger instance has only the one appender (the custom JDBC appender which I wrote). It has no console appender etc. But, when logging happens, log statements get printed on the server console and also in the application log files. I should mention that the application log4j.xml file does have the console and file appender. I initialise the Logger instance as follows: Logger customLogger = Logger.getLogger("myCustomLogger"); / / remove all appenders associated with customLogger customLogger.removeAllAppenders(); // add JDBCAppenderService to customLogger customLogger .addAppender(new JDBCAppenderService(ds)); //ds is the datasource name << Now, I use customLogger to log the information as follows: customLogger.info(logObject) //logObject contains the data to be logged << I want customLogger to remained unaffected by the settings in the log4j.xml file. So, if the logging level in log4j.xml is set to OFF, I still want the JDBC appneder to work i.e log data in the database. Please let me know if there any way to achieve this ?? Or does the log4j.xml configuration overrides the settings in the class files ?? Thanks and Regards, Aneez Backer

Using a rolling log file across multiple .ear/.war files

Friedman, Brent — 2008-08-18T14:06:43

I have used log4j in the past, but I am trying to use it now for something where I am running into problems. Any suggestions/advice would be appreciated. I can't get a file logger to roll files. When the file reaches its preset size, it overwrites the original file instead of rolling. This situation involves a web app that includes multiple .ear files. Each .ear file has its own log, and there is a common log file across the web app. I would like to create a separate log file which can be accessed by specific pieces of each application, e.g., a special purpose log file. My current attempts have not been able to define a rolling log file. The environment is Websphere 6.0.2.x running on Windows 2003 Server. My google attempts have indicated a possible problem with multiple .ear/.war attachments to a single log file may cause problems with rolling, but there didn't seem to be a work-around. Having separate log files for this specific event log across multiple .ear/.war files would be a nightmare to debug. So, how can I use a single rolling log file to function properly across multiple .ear/.war components in a single web app? Thanks, Brent Friedman

Thread org.apache.log4j.xml.XMLWatchdog

Martin Kalany — 2008-08-18T11:35:56

Hi folks, When I use the profiling tool off the Netbeans 6.1 IDE, I see lots of Threads that got the name "org.apache.log4j.xml.XMLWatchdog". Unfortunately I didn't find much documentation about that, that's why I'm posting here. My problem is that there's lot's of threads (about 5 per instance of B) with this name when I profile code that looks like the code below. Why is that? Does log4j really need them? The profiler says they are waiting all the time. Regards, Martin java-code: class A{ DOMConfigurator.configure("log4j_config.xml"); Logger loggerA = Logger.getLogger("loggerA"); B b1 = new B(); B b2 = new B(); B b3 = new B(); } class B{ Logger loggerB = Logger.getLogger("loggerB"); } log4j_config.xml:
