Let's say my server started at 3:00 PM and I have 5 log files
server.log
server.log.2022-01-19-15-1 (1 MB)
server.log.2022-01-19-15-2 (1 MB)
server.log.2022-01-19-15-3 (1 MB)
server.log.2022-01-19-15-4 (1 MB)
server.log.2022-01-19-15-5 (1 MB)
Some time it will add in older file created (like server.log.2022-01-19-15-2, server.log.2022-01-19-15-1) instead of latest file
Why logs are added in already rotated file instead of latest highest number log file?

Hello i am migrating to latest log4j version and migrated from 1.x to 2.x log4j. So here is my log4j2 config file. I am stuck with debug and error logs, maybe someone could see that if there should be something different.

Currently, my logs are generating 1 file per day.
But I want to compress the log files older than 5 days and delete them after 10 days.
how can I achieve this?

Im usign log4j2 for logging. I need daily logging with keeping a backup of 5 days logs. My log4j2.xml looks as below. My backup files keep on increasing in number eventhough ive limited the number to 5. Where did i go wrong??

Instead of the max consider using the delete rule.
I am getting this error:
ERROR asyncRoot contains an invalid element or attribute "immediateFlush"
When I use immediateFlush attribute in appender in log4j2.xml.
<Appenders>
<Console name="STDOUT" target="SYSTEM_OUT">

</Policies>
<DefaultRolloverStrategy max="1000">

Try with this modification:
<RollingFile name="csroot"
fileName="${cslogs}/cslog.log" filePattern="${cslogs}/$${date:yyyy-MM}/cslog-%d{yyyy-MM-dd}-%i.log" immediateFlush="false">
<PatternLayout pattern="%d{dd-MM-yy HH:mm:ss} [$${ctx:instId} - $${ctx:userId}] %c.%M(%L)- %m%n"/>

immediateFlush is not an attribute of PatternLayout.
I know its quite an old question but might help somebody.
RollingFile Appender Parameters points out the immediateFlush is the property of the appender. But you have it declared as an attribute for PatternLayout which is what is causing the error.
Sample RollingFile appender configuration:
<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="warn" name="MyApp" packages="">
<Appenders>
<RollingFile name="RollingFile" fileName="logs/app.log"
filePattern="logs/$${date:yyyy-MM}/app-%d{MM-dd-yyyy}-%i.log.gz"
immediateFlush="false">
<PatternLayout>
<Pattern>%d %p %c{1.} [%t] %m%n</Pattern>
</PatternLayout>
<Policies>
<TimeBasedTriggeringPolicy/>
<SizeBasedTriggeringPolicy size="250 MB"/>
</Policies>
</RollingFile>
</Appenders>
<Loggers>
<Root level="error">
<AppenderRef ref="RollingFile"/>
</Root>
</Loggers>
</Configuration>
I'm use to RollingFileAppender on normal log4j. Now I'm switching to log4j2, and cannot get the appender to work.
The File appender below works as expected. But the logging file for RollingFile is never created. Why?
<?xml version="1.0" encoding="UTF-8"?>
<Configuration>
<Appenders>
<File name="FILE" fileName="c:/logs.log">
<PatternLayout pattern="%d %p %c: %m%n" />
</File>
<RollingFile name="ROLLING" fileName="c:/logsroll.log">
<PatternLayout pattern="%d %p %c: %m%n"/>
<Policies>
<TimeBasedTriggeringPolicy />
<SizeBasedTriggeringPolicy size="0.001 MB"/>
</Policies>
<DefaultRolloverStrategy max="10"/>
</RollingFile>
</Appenders>
<Loggers>
<Root level="info">
<AppenderRef ref="FILE" />
<AppenderRef ref="ROLLING" />
</Root>
</Loggers>
</Configuration>
The RollingFile tag is missing a filePattern attribute.
<RollingFile name="ROLLING"
fileName="c:/logsroll.log"
filePattern="c:/logsroll-%i.log">
I used log4j2 version 2.0, in some cases it throws error if you do not set any date in file pattern, in this case you can use some thing like below:
<RollingFile name="MyFile" fileName="d:/log/bsi/admin/total/totalLog.log"
filePattern="d:/log/totalLog-%d{MM-dd-yyyy}-%i.log">
<PatternLayout>
<Pattern>%d %p %c [%t] %m%n</Pattern>
</PatternLayout>
<Policies>
<TimeBasedTriggeringPolicy />
<SizeBasedTriggeringPolicy size="1 MB"/>
</Policies>
<DefaultRolloverStrategy max="2000"/>
</RollingFile>
