We have set log4j rollover as 500mb upon 500 mb it is creating a file new file log.1 but still it is sometimes writing to log.1 and to log and sometimes only to log and some times to log.1.
I am using apache tomcat.
It is so inconsistent.
<!-- Appenders -->

Could you please let me know any reason for this?

I have errorAppender and infoAppender to separate in 2 log files.
That is working, but I need to log in info file only info information.
Example:
when I call logger.error("TEST ERROR"), I don't want this showing on info file.
is there any way to disable level logs?

I have a Log4J xml config file with appenders in it.
<appender name="stdout" class="org.apache.log4j.ConsoleAppender">
<param name="File" value="/tomcat/website/webapps/app/logs/appInfo.log" />
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%d{MMM dd HH:mm:ss} %F: %m%n" />
</layout>
</appender>
<appender name="rolling" class="org.apache.log4j.RollingFileAppender">
<param nawebsite/webapps/app/logs/app.log" />
<param name="MaxFileSize" value="1000KB" />
<param name="MaxBackupIndex" value="2" />
<param name="DatePattern" value="'.'yyyy-MM-dd'" />
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%d{MMM dd HH:mm:ss} %F: %m%n" />
</layout>
</appender>
When I build my project, I get the following warnings/errors in the console which I am trying to get rid of:
log4j:WARN No such property [datePattern] in org.apache.log4j.RollingFileAppender.
log4j:WARN No such property [file] in org.apache.log4j.ConsoleAppender.
I did not make these log4j config xml files; they were already part of the project.
I've seen the DatePattern documentation online, and it seems to suggest exactly what is in the DatePattern value, so I have no idea why it's still showing me that warning. Same with file.
Did the person who made this before me just stick properties in these appenders that do not belong? I'm having a difficult time verifying this.
Every Appender has it's own configuration properties. file make sense for RollingFileAppender but doesn't make sense for ConsoleAppender.
If you switch one appender to another and do not update configuration properties, then you will get such warnings.
To fix them, you need to remove unused (or inapplicable) properties from your configuration:
<appender name="stdout" class="org.apache.log4j.ConsoleAppender">
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%d{MMM dd HH:mm:ss} %F: %m%n" />
</layout>
</appender>
<appender name="rolling" class="org.apache.log4j.RollingFileAppender">
<param name="FileName" value="/tomcat/website/webapps/app/logs/app.log" />
<param name="MaxFileSize" value="1000KB" />
<param name="MaxBackupIndex" value="2" />
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%d{MMM dd HH:mm:ss} %F: %m%n" />
</layout>
</appender>
Complete list of appenders and their parameters is available on the Apache Commons Log4j webpage:

I am using log4j for my application for printing logs. Till now, I have only one log file(say X.log) and it is getting rolled after a fixed size, say, 4 MB. Now , I am trying to log some particular requests and responses to a different log file, Y. Log.
My requirement is to roll the Y.log file also, after 4 MB. I am using rolling file appender for both X and Y logs. Y.log will be created in the same location where X.log is available.
But it seems like now both the log files are not getting rolled over after 4 MB. It is keep on appending to the same logs and the size is increasing. Below is my log4j configuration.
<appender name="Xlogfile" class="org.apache.log4j.RollingFileAppender">
<param name="append" value="true" />
<param name="file" value="/logs/X.log" />
<param name="MaxBackupIndex" value="200" />
<param name="MaxFileSize" value="4MB" />
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%d{dd MMM yyyy HH:mm:ss} %5p %c{1} - %m%n"/>
</layout>
</appender>
<appender name="Ylogfile" class="org.apache.log4j.RollingFileAppender">
<param name="append" value="true" />
<param name="file" value="/logs/Y.log" />
<param name="MaxBackupIndex" value="200" />
<param name="MaxFileSize" value="4MB" />
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%d{dd MMM yyyy HH:mm:ss} %5p %c{1} - %m%n"/>
</layout>
</appender>
<root>
<level value="INFO" />
<appender-ref ref=" Xlogfile " />
<appender-ref ref=" Ylogfile " />
</root>
Could anyone please provide me a solution for this. Thanks in advance.
Try adding a policy to your appender, like this:
<Policies>
<SizeBasedTriggeringPolicy size="4mb"/>
</Policies>
I am using log4j for logging in my applicaion. I am trying to different level logs in different files but something going wrong. Any help regrading this issue will be highly appreciated.

The standard behaviour for log4j appenders is that they log all messages at their threshold level or higher, i.e. an appender with threshold INFO will log INFO, WARN, ERROR and FATAL messages but not DEBUG. If you want to log only INFO messages but not WARN and above then you need to use a LevelMatchFilter.
You will also need to set your root logger priority to DEBUG, otherwise it will only send ERROR and FATAL messages to its appenders and your DEBUG and INFO files will be empty.
I am working on a Spring WebFlow Project. I can't stop log4j from printing debug statements. can someone please tell me how to get it to stop putting debug statments on the console and log.
I see this warn as my server starts:
log4j:WARN Continuable parsing error 42 and column 11
log4j:WARN The content of element type "logger" must match "(level?,appender-ref*)".

This is just a log4j issue. It appears that <priority> is not a valid sub-element of the logger element <root>. Rather, you should have <level> instead.
