I am trying to add AsyncLogger to log4j.properties. I have found examples of adding AsyncLogger to lo4j.xml file, but not to log4j.properties. Can you please let me know how to add it. Please provide a sample log4j.properties entry for AsyncLogger.
Thanks
You can't AsyncAppenders need to be configured by code or XML

After migrating from log4j v1.2 to log4j2, I have encountered some issues I am not sure how to solve.
I believe I have managed to change my xml-configuration and the logger initialization in the class files I have, but the IDE tells me that No appenders could be found for logger (org.apache.http.client.protocol.RequestAddCookies)
It shouldn't be necessary to add a logger to classes/ packages I haven't created right? Maybe I am just missing the big picture here, but I hope you can guide me.
Thanks in regards
You use <AppenderRef ref="File"/> but appender File is not defined.
If you want to log everything to console, just change File to Console.
If you want to log to file, define File appender.
How can i disable whole configuration?
I tried setting Root Status to off, but then it is not writing into log files and the log files are getting generated as empty files.
I don't want log files to be generated if root status is off... Please suggest if there is any way.
You'll need to set a property on your FileAppender to create the file on demand.
See createOnDemand here:
https://logging.apache.org/log4j/2.x/manual/appenders.html
An example:
<RollingFile name="RollingLogFile"
fileName="logs/rolling.log"
filePattern="logs/rolling-%d{yyyy-MM-dd-HH-mm}.log.gz"
createOnDemand="true">
I am using web-based application along with Log4J API for logging purpose.
In Log4J, I am using DailyRollingFileAppender to create a new log file for logging on each day.
here is my log4j properties file configuration
log4j.logger.org.apache.cxf=ERROR
log4j.rootLogger=INFO, jtiServiceAppender
log4j.appender.jtiServiceAppender=org.apache.log4j.DailyRollingFileAppender
log4j.appender.jtiServiceAppender.File=${catalina.home}/logs/jti/ilume-mw${logfilename}-app.log
log4j.appender.jtiServiceAppender.DatePattern='.'yyyy-MM-dd
log4j.appender.jtiServiceAppender.layout=org.apache.log4j.PatternLayout
log4j.appender.jtiServiceAppender.layout.ConversionPattern=%d{dd.MM.yyyy HH\:mm\:ss} %-5p %t [%C{1}]\: %m%n
Problem:
In my case, the log files are not created for each day. For the same when I checked my tomcat server log I have observed that I am getting an error as
log4j:ERROR Failed to rename [D:\ilume-mwtmp0-app.log] to
[D:\ilume-mwtmp0-app.log.2019-07-09].
I have also referred the below link however still, I did not find a proper solution to my case.

Any help or suggestion to solve this logging problem will be highly appreciated as it's been a couple of days and I am still not able to get any proper solution to this problem.
When adding appender-ref in logger tag, it throws renaming error. When adding appender-ref in root tag, it never throws that error.
Above is from below link. It seems same error and might help.
log4j:ERROR Failed to rename
Other than above, please check if there is permission issue at the directory where file needs to be renamed.
I have created a code using jackrabbit-standalone-2.4.2.jar and i am getting jackrabbit.log_IS_UNDEFINED.log file in the project directory. This log file is very huge(close to 1 GB). I want to disable it but i dont know how. Does anybody have any idea to deal with situation?
To remove this file you have to (as stated in the file name) to define the logger that you want to use.
Since jackrabbit is relying on slf4j, you should configure properly a logger for it.
For instance you can add to you dependencies the lf4j-log4j12 implementation, plus a log4j.properties in your classpath.
You can also configure any other slf4j implementation.
I have solved this issue by removing logback.xml and slf4j.jar from jackrabbit-standalone.jar and adding slf4j.jar and slf4j-lo4j.jar in the classpath of the project. Now jackrabbit.log_IS_UNDEFINED.log is gone and i am getting desired logs :)
I am using log4j for loggin purpose in my application. Since now to configure the logging i was using the following code :
LogManager.resetConfiguration();
InputStream stream = Thread.currentThread().getContextClassLoader().getResourceAsStream("log4j.properties");
Properties props= new Properties();
props.load(stream);
PropertyConfigurator.configure(props);
But the problem with this was , that whenever i wanted to change the logging level during the process, i had to restart the server. So i changed the code to :-
LogManager.resetConfiguration();
PropertyConfigurator.configureAndWatch(("log4j.properties", 900000L);
this code ideally should help to re-load the log4j.properties file after the time specified, which i have mentioned as 15 minutes. But still the code is not working
Am i missing somthing during the code?
Regards.
configureAndWatch() watches files. Not resources in the classpath.
I tried the solution and works fine! The point is that your must provide the path like a file not like a resource.
//Resource
DOMConfigurator.configureAndWatch("/log4j.xml", 2000L);
//File
DOMConfigurator.configureAndWatch("./src/log4j.xml", 2000L);
Try the second option and modify the log4j.xml and test it!
