I'm using log4j2 version 2.19.0.
I want to delete the old files in Tomcat folder. But when I run my program, the files was not deleted.
appender.rolling.type = RollingFile
appender.rolling.name = LogToRollingFile
appender.rolling.fileName = /var/lib/tomcat/logs/logger.log
appender.rolling.filePattern = /var/lib/tomcat/logs/logger.%d{dd-MM-yyyy}.log.gz
appender.rolling.layout.type = PatternLayout
appender.rolling.layout.pattern = %d{yyyy-MM-dd HH:mm:ss} %-5p %m%n
appender.rolling.policies.type = Policies
appender.rolling.policies.time.type = TimeBasedTriggeringPolicy
appender.rolling.policies.time.interval = 1
appender.rolling.policies.time.modulate = true
appender.rolling.strategy.type = DefaultRolloverStrategy
appender.rolling.strategy.delete.type = Delete
appender.rolling.strategy.delete.basePath = /var/lib/tomcat/logs/
appender.rolling.strategy.delete.maxDepth = 1
appender.rolling.strategy.delete.ifLastModified.type = IfLastModified
appender.rolling.strategy.delete.ifLastModified.age = 2d
# Log to console and rolling file
logger.app.name = aHello
logger.app.level = info, error
logger.app.additivity = false
logger.app.appenderRef.rolling.ref = LogToRollingFile
rootLogger.level = info
I check the /var/log/ folder, and I saw the below error
2022-09-22 14:53:38,384 Log4j2-TF-1-RollingFileManager-1 ERROR Error in post-rollover Delete when visiting /var/lib/tomcat/logs java.nio.file.FileSystemException: /var/lib/tomcat/logs: Read-only file system
Is there any other method I can use to delete the log file by using lo4j2 library?
Currently, I already include the log4j api and core lib to my code.
Thank you.
As per mentioned in comment, answer works for changing the part to /var/log/tomcat

I have 2 questions regarding Log4j2.
How can I set that warnings and errors of referenced Jar files to output in the log file instead of the console? Currently, log statements in my application are being printed in the log file. But those messages from the referenced Jar files are being printed in the console instead.
How can I set Japanese characters to be printed in the generated logfile? Currently, I have set charset of layout but the output of Japanese characters are still in "?" or garbage characters.
This is my current property file:
status = error
name = PropertiesConfig
property.filename = ${sys:user.home}\\myApp\\logs\\application.log

filter.threshold.type = ThresholdFilter
filter.threshold.level = debug
#filter.threshold.level = info

I assume you mean 'external third party libraries' by 'referenced jar files'. Libraries usually use a logger abstraction like apache.commons.logging or slfj4 for issuing its log outputs.
You need to add an additional dependency which bridges these log outputs correctly to your log4j2-Logger. e.g. "org.apache.logging.log4j:log4j-slf4j-impl:2.7".
If you do not provide such a bridge the log abstraction framework might do default initialization (which probably logs to console).
I'm trying to integrate Sentry in my Maven project that already uses log4j2.properties as log4j2 configuration file.
The official documentation has just log4j2.xml as configuration example.
What is the way to configure the same example with log4j2.properties?
I've the same problem.
Here is my log4j2.properties
appenders = console,Sentry
appender.console.type = Console
appender.console.name = STDOUT
appender.console.layout.type = PatternLayout
appender.console.layout.pattern = ${env:log4j.csl.pattern:-info}
appender.Sentry=io.sentry.log4j.SentryAppender
appender.Sentry.name=Sentry
appender.Sentry.type=Sentry
rootLogger.level = ${env:log4j.root.loglevel:-info}
rootLogger.appenderRefs = stdout
rootLogger.appenderRef.stdout.ref = STDOUT
loggers=csl,sentry
logger.csl.name = io.sirnino
logger.csl.level = ${env:log4j.csl.loglevel:-debug}
logger.csl.additivity = false
logger.csl.appenderRefs = stdout
logger.csl.appenderRef.stdout.ref = STDOUT
logger.sentry.name = sentry
logger.sentry.level = WARN
logger.sentry.appenderRefs = Sentry
The app starts properly but, in a nutshell, seems to ignore the Sentry logger. Any idea?
This solution for integrating sentry with log4j2.properties worked for me perfectly along with stdout logging.
log4j.rootLogger=INFO, stdout, sentry
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} [%t] %-5p %c{1}:%L - %m%n
log4j.appender.sentry=io.sentry.log4j.SentryAppender
log4j.appender.sentry.Threshold=error
For this, I had to add log4j 1.x version of sentry to my pom.xml
In my case with log4j 2.17, I needed to add packages = io.sentry.log4j2 to my log4j2.properties file.
Full file:
status = error
dest = err
name = MyName
packages = io.sentry.log4j2
monitorInterval = 5
appender.console.type = Console
appender.console.name = LogToConsole
appender.console.layout.type = JsonLayout
appender.console.layout.compact = true
appender.console.layout.eventEol = true
appender.console.layout.properties = true
appender.sentry.name = Sentry
appender.sentry.type = Sentry
appender.sentry.dsn = https://key#my.domain.com
rootLogger.level = ${env:LOG_LEVEL:-debug}
rootLogger.appenderRef.console.ref = LogToConsole
rootLogger.appenderRef.sentry.ref = Sentry
It should work also with log4j2.properties. Have you tried and it failed?
Maybe the docs should explicitly state that it's supported.
If it doesn't work, you can raise an issue on GitHub:

I'm having trouble using Log4J (version 2.13.0), with the following problems:
I have no idea if my log4j.properties file is configured properly, or even recognized for that matter.
Log4J is not using the pattern I've specified nor allowing me to log any trace/debug/info/warn messages.
This is my log4j.properties file:
status = trace
dest = out
name = PropertyConfiguration
property.filename = logs/log%d{yyyy-MM-dd HH:mm:ss}.log
property.pattern = %d{yyyy-MM-dd HH:mm:ss} | [%-5p] %c{1}:%L: %m%n
appender.console.type = Console
appender.console.name = STDOUT
appender.console.layout.type = PatternLayout
appender.console.layout.pattern = ${pattern}
appender.rolling.type = RollingFile
appender.rolling.name = RollingFile
appender.fileName = ${filename}
appender.rolling.filePattern = logs/log-%d{MM-dd-yyyy-HH-mm-ss}.log
appender.rolling.layout.type = PatternLayout
appender.rolling.layout.pattern = ${pattern}
appender.rolling.policies.type = Policies
appender.rolling.policies.time.type = TimeBasedTriggeringPolicy
appender.rolling.policies.time.interval = 2
appender.rolling.policies.time.modulate = true
appender.rolling.strategy.type = DefaultRolloverStrategy
appender.rolling.strategy.max = 5
logger.rolling.name = me.tecc
logger.rolling.level = trace
logger.rolling.additivity = false
logger.rolling.appenderRef.rolling.ref = RollingFile
rootLogger.level = trace
rootLogger.appenderRef.stdout.ref = STDOUT
Any help would be appreciated. Thanks!
Log4J is not using the pattern I've specified nor allowing me to log any trace/debug/info/warn messages.
Unlike its predecessor Log4J 1.x, Log4J 2 did not support
configuration through the properties file when it was initially
released. It was from Log4J 2.4 that support for the properties
file was again added, but with a completely different syntax
I see that your Log4j version is 2.13 which falls below 2.4 , so it wont work.
Kindly pay attention:
The PropertyConfigurator(log4j.properties) does not handle the advanced configuration features supported by the DOMConfigurator(log4j.xml) such as support custom ErrorHandlers, nested appenders such as the AsyncAppender, etc.
appender.fileName = ${filename}
you miss the "rolling" part in this config. try again after change it as follows
appender.rolling.fileName = ${filename}
My logger is printing out logs to my console, but I want it to append my .log file. I placed the following poperties inside my application.properties file:
log4j.rootLogger = DEBUG, stdout, stderr, dailyfile
log4j.appender.stdout.Threshold = INFO
log4j.appender.stdout = org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout = org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=[%d] %5p %m (%C::%M:%L)%n
log4j.appender.stderr.Threshold = ERROR
log4j.appender.stderr = org.apache.log4j.ConsoleAppender
log4j.appender.stderr.layout = org.apache.log4j.PatternLayout
log4j.appender.stderr.layout.ConversionPattern=[%d] %5p %m (%C::%M:%L)%n
log4j.appender.dailyfile.Threshold = DEBUG
log4j.appender.dailyfile = org.apache.log4j.DailyRollingFileAppender
log4j.appender.dailyfile.File = ../webapps/test/a.log
log4j.appender.dailyfile.layout = org.apache.log4j.PatternLayout
log4j.appender.dailyfile.layout.ConversionPattern=[%d] %5p {%t} %m (%C::%M:%L)%n
log4j.appender.dailyfile.DatePattern ='.'yyyy-MM-dd
And I have a few log.info() calls in my code:
log.info("bla bla bla bla");
For now my logs are visible on the console. This code can't create a file somehow. Even if I create the file manually, it is not being updated (appended). What should I do in order for my code to work?
I didn't know, that file with Log4j properties has to be named exactly log4j.properties. In my case all I had to do was create file, place all properties inside and move this file to src/resources. Thanks for help guys!
I was implementing log file based on the time and date using Log4j tool for my java application I am facing problem when i am including both file appender (RollingFileAppender and DaillyRollingFileAppender) in the same properties file. This is the properties configuration i was trying .any clue would be appreciated .
log=logs log4j.rootLogger = DEBUG, FILE
log4j.appender.FILE = org.apache.log4j.RollingFileAppender
log4j.appender.FILE.File = log/log.txt log4j.appender.FILE.Append = true
log4j.appender.FILE.MaxFileSize = 1kb
log4j.appender.FILE.layout = org.apache.log4j.PatternLayout
log4j.appender.FILE.layout.conversionPattern = [%p] %d %c %M -%m%n%n
It should be
log4j.rootLogger = DEBUG, FILE
instead of
log=logs log4j.rootLogger = DEBUG, FILE
one property per line
log4j.rootLogger = DEBUG, FILE
log4j.appender.FILE = org.apache.log4j.RollingFileAppender
log4j.appender.FILE.File = log/log.txt
log4j.appender.FILE.Append = true
log4j.appender.FILE.MaxFileSize = 1kb
log4j.appender.FILE.layout = org.apache.log4j.PatternLayout
log4j.appender.FILE.layout.ConversionPattern = [%p] %d %c %M -%m%n%n
