I am sure that this question is answered multiple times. But somehow, it's not working for me.
My appender is something like this.
<appender name="myAppender" class="org.apache.log4j.DailyRollingFileAppender">
<param name="Threshold" value="DEBUG"/>
<param name="File" value="D:\\out\\MyApp_${output}.log"/>
<param name="DatePattern" value="'.'yyyy-MM-dd"/>
<param name="Append" value="true"/>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%d{DATE} %5p %C{1}:%L - %m%n"/>
</layout>
</appender>
I am setting the system property before creating the logger.
System.setProperty("output", "abc");
Then, I am creating the logger like this.
logger = Logger.getLogger("myAppender");
But the output file is generated only like this.
MyApp_.log
Am I missing something? Thanks in advance.
Did you try -Doutput=abc during the startup?
Here is another thread with similar problem that may help you.
How to give environmental variable path for file appender in configuration file in log4j

I have a log4J.xml SMTPAppender configuration as follows:
<appender name="MAIL" class="org.apache.log4j.net.SMTPAppender">
<param name="Threshold" value="ERROR"/>
<param name="EvaluatorClass" value="fi.reaktor.log4j.emailthrottle.ErrorEmailThrottle"/>
<param name="BufferSize" value="512"/>
<param name="SMTPHost" value="xxxx"/>
<param name="SMTPPort" value="25"/>
<param name="From" value="xxxx"/>
<param name="To" value="xxx"/>
<param name="Subject" value="xxx"/>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%d{dd/MM/yyyy HH:mm:ss} [%-5p] [%c{1}: %M] %m%n"/>
</layout>
</appender>
I use an EvaluatorClass that I was advised on the link: https://github.com/reaktor/log4j-email-throttle
On the page, it was marked that you can change the default configuration in a log4j.properties file:
fi.reaktor.log4j.emailthrottle.throttleIfUnderSecs=60
fi.reaktor.log4j.emailthrottle.emailIntervalInSecs=900
fi.reaktor.log4j.emailthrottle.normalAfterSecs=3600
Unfortunately, I do not see how to apply it in my Log4j.xml file.
The page you refer to says:
You can change default values by setting these System properties
So you can't put those settings in log4j config file.
You either need to set those properties on the command line where you start jvm, with "-D" flag:
java -Dfi.reaktor.log4j.emailthrottle.throttleIfUnderSecs=60 \
-Dfi.reaktor.log4j.emailthrottle.emailIntervalInSecs=900 \
-Dfi.reaktor.log4j.emailthrottle.normalAfterSecs=3600
or set it from your code programmatically:
System.setProperty("fi.reaktor.log4j.emailthrottle.throttleIfUnderSecs", "60");
System.setProperty("fi.reaktor.log4j.emailthrottle.emailIntervalInSecs", "900");
System.setProperty("fi.reaktor.log4j.emailthrottle.normalAfterSecs", "3600");
I want to change the appender pattern for the log4J logging so that the exported files end with a .log extension rather than.log.[Date] as its easier to get windows to open the file. e.g.
I want files named like this
name.log
name.2016-01-26.log
name.2016-01-27.log
Instead of this
name.log
name.log.2016-01-26
name.log.2016-01-27
Current configuration for the appender
<log4j:configuration>
<appender name="rollingfile" class="org.apache.log4j.DailyRollingFileAppender">
<param name="File" value="../logs/name.log"/>
<param name="DatePattern" value="'.'yyyy-MM-dd"/>
<param name="Append" value="true"/>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="[%d] %-5p [%t] %c{1} - %m%n"/>
</layout>
</appender>
Not sure which version of log4j you are using. Anyway regardless which version, you can always write your own Appender that extends the original one.
Take this as an example, you will see it always append the date to the end of the filename. What you can do is to extend the original class and overwrite its activateOptions method.
Alternatively, you can specify the DatePattern as '.'yyyy-MM-dd'.log'. However in this way your rolling log filename will be something like "name.log.2016-01-27.log".
My appender is defined as below:
<appender name="M_FILE" class="org.jboss.logging.appender.RollingFileAppender">
<errorHandler class="org.jboss.logging.util.OnlyOnceErrorHandler"/>
<param name="File" value="${jboss.server.home.dir}/log/m_ser.log"/>
<param name="Append" value="false" />
<param name="MaxFileSize" value="5MB"/>
<!--param name="MaxBackupIndex" value="25"/-->
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%d{ABSOLUTE} %-5p [%c] %m%n"/>
</layout>
</appender>
<root>
<appender-ref ref="M_FILE"/>
</root>
With this, I get m_ser.log upto 5MB, then it created m_ser.log.1, then it it created m_ser.log.2 and m_ser.log.1 file is missing. After a while, m_ser.log.3 got created and m_se.log.2 is missing.
It looks like the log4j is overwriting the backup files or it is unable to keep the old file.
This is log4j 1.2, Windows 7 system and JBoss 4.1
The MaxBackupIndex parameter should define how many backup files (.1,.2,.3, etc) are kept before it starts overwriting them.
I have an app running on Tomcat 7.0.2 and using log4j for logging.
Shortly after tomcat start the following messages appear in catalina.out:
INFO: Initializing log4j from [file:///export0/home/tomcat/appconf/log4j.xml]
log4j:WARN Unrecognized element rollingPolicy
log4j:WARN Please set a rolling policy for the RollingFileAppender named 'PERFFILE'
log4j:WARN Unrecognized element rollingPolicy
log4j:WARN Please set a rolling policy for the RollingFileAppender named 'FILE'
and when my actual log messages should print, I see the following:
log4j:ERROR No output stream or file set for the appender named [FILE].
log4j:ERROR No output stream or file set for the appender named [PERFFILE].
These two appenders are defined like this:
<appender name="FILE" class="org.apache.log4j.rolling.RollingFileAppender">
<param name="Append" value="true" />
<param name="File" value="${catalina.base}/logs/server.log" />
<rollingPolicy class="com.myapp.logging.AgingTimeBasedRollingFilePolicy">
<param name="fileNamePattern" value="${catalina.base}/logs/archive/server.%d{yyyy-MM-dd}.log.gz" />
<param name="keepFilesForDays" value="30" />
</rollingPolicy>
<layout class="com.myapp.logging.jboss.WebappAwarePattern">
<param name="ConversionPattern" value="%d{ISO8601}{${server.localTimezone}} %p [%X{webapp}:%c{2}] %m%n" />
</layout>
</appender>
<appender name="PERFFILE" class="org.apache.log4j.rolling.RollingFileAppender">
<param name="Append" value="true" />
<param name="File" value="${catalina.base}/logs/performance.log" />
<rollingPolicy class="com.myapp.logging.AgingTimeBasedRollingFilePolicy">
<param name="fileNamePattern" value="${catalina.base}/logs/archive/performance.%d{yyyy-MM-dd}.log.gz" />
<param name="keepFilesForDays" value="30" />
</rollingPolicy>
<layout class="com.myapp.logging.jboss.WebappAwarePattern">
<param name="ConversionPattern" value="%d{ISO8601}{${server.localTimezone}} %p [%X{webapp}:%c{2}] %throwable{0} %m%n" />
</layout>
</appender>
I've been having a hard time trying to fugure out why this errors occur but got no result (probably my log4j.xml can not be parsed correctly)
So any ideas why this happens would be highly appreciated.
Thanks in advance!
Taken from the Appenders documentation page:
Parameter Name Type Description
policy TriggeringPolicy The policy to use to determine
if a rollover should occur.
I think you should replace rollingPolicy with policy. This probably depends on whether you are using 2.0 or 1.2; I dont see policy in the 1.2 version.
I think you set the wrong class or your custom class for the rollingPolicy class on your two appenders that maybe not exist or not recognize by log4j
<rollingPolicy class="com.myapp.logging.AgingTimeBasedRollingFilePolicy">
So change both appenders class with:
<rollingPolicy class="org.apache.log4j.rolling.TimeBasedRollingPolicy">
that have been provided by apache-log4j-extras jar
I have setup TimeBasedRollingPolicy to rollout the file every minute (for test purpose) and the problem I am facing is a warning and no zip or gz file is being created. Warning is:
log4j:WARN Failure in post-close rollover action
I attached the source to figure-out the problem but have no success yet. Am I missing any configuration in my log4j.xml?
<appender name="errorAppender" class="org.apache.log4j.rolling.RollingFileAppender">
<param name="File" value="C:/error.log"/>
<param name="Append" value="true"/>
<param name="BufferedIO" value="true"/>
<rollingPolicy class="org.apache.log4j.rolling.TimeBasedRollingPolicy">
<param name="FileNamePattern" value="C:/error.%d{ddMMMyyyy HH:mm:ss}.log.gz" />
<param name="ActiveFileName" value="C:/error.log"/>
</rollingPolicy>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%d [%t] %-5p %C (line:%L) - %m%n"/>
</layout>
<filter class="org.apache.log4j.varia.LevelRangeFilter">
<param name="LevelMax" value="error"/>
<param name="LevelMin" value="error"/>
<param name="AcceptOnMatch" value="true"/>
</filter>
</appender>
I am using log4j-1.2.17 and apache-log4j-extras-1.1. Has anybody seen this problem or have any clue about it?
Problem with "log4j:WARN Failure in post-close rollover action" message is that in windows-based systems you can not create a file name with the ":" char, so the FileNamePattern specified should not contain any one of these: \, /, :, *, ?, ", <, >, |
Here it is a log4j.xml for my application that works fine using a rolling file appender. For testing purposes I made the rolling to create a new file every second:
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">
<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/">
<appender name="consola" class="org.apache.log4j.ConsoleAppender">
<param name="target" value="System.out"/>
<layout class="org.apache.log4j.PatternLayout">
<param name="conversionPattern" value="[%d{yyyyMMdd HH:mm:ss:mm,SSS}]%-5p [%t] [%c{1}-%M:%L] - %m%n"/>
</layout>
</appender>
<appender name="desarr" class="org.apache.log4j.rolling.RollingFileAppender">
<param name="Append" value="false"/>
<rollingPolicy name="desarr" class="org.apache.log4j.rolling.TimeBasedRollingPolicy">
<param name="fileNamePattern" value="C:/workspace/Probador/log/backups/importacion222.log_%d{mmss_mm}"/>
<param name="activeFileName" value="C:/workspace/Probador/log/importacion222.log"/>
</rollingPolicy>
<layout class="org.apache.log4j.PatternLayout">
<param name="conversionPattern" value="[%d{yyyyMMdd HH:mm:ss:mm,SSS}]%-5p [%t] [%c{1}-%M] - %m%n"/>
</layout>
</appender>
<root>
<priority value ="debug" />
<appender-ref ref="consola" />
<appender-ref ref="desarr"/>
</root>
</log4j:configuration>
Special attention to:
<param name="fileNamePattern" value="C:/workspace/Probador/log/backups/importacion222.log_%d{mmss_mm}"/>
Try this before attempting to zip the file.
I hit the same issue in log4j with WARN message - "log4j:WARN Failure in post-close rollover action" and the log file was not rolling over. It was root caused to insufficient permission issue on the directory into which log file was getting written. In this case, Java's File.renameTo() method was failing silently (just returns a boolean false). Took lot of time to figure out the issue :(
I am using log4j-1.2.17 and apache-log4j-extras-1.1. Has anybody seen
this problem and have any clue about it?
I have also observed this problem using log4j-1.2.16 and apache-log4j-extras-1.1. The exact same message.
I have tried various tweaks to no avail. The only time when rollingPolicy->FileNamePattern seems to be observed is when it is used without the appender->File parameter and rollingPolicy->ActiveFileName parameter. But even still I have not seen it rollover successfully nor gz or zip previous files.
I also get the same messages:
log4j: setFile called: somepath/somefile.log, true
log4j: setFile ended
log4j:WARN Failure in post-close rollover action
Very frustrating.
For me the solution was to create manually the directory for archived files.
I Also had the same problem,but in my case it was because of the fact that the 'fileNamePattern' path folder did not exist. Rectifying that worked for me and the rollover files were being created then.
If you are using the org.apache.log4j.rolling.TimeBasedRollingPolicy rollingPolicy, then the directory must exist prior to log4j being able to rotate.
For example, the following rollover will only work if /var/log/blah/archive/YYYY/MM directory exists; create it in a nightly cronjob should do the trick. And, as mentioned previously, this will also occur when there is not enough permission to create the log file.
<appender name="infoFile"
class="org.apache.log4j.rolling.RollingFileAppender">
<param name="threshold"
value="INFO"/>
<param name="append"
value="true"/>
<rollingPolicy class="org.apache.log4j.rolling.TimeBasedRollingPolicy">
<param name="ActiveFileName"
value="/var/log/blah/file.log"/>
<!-- IMPORTANT the archive folder must already exist, or log4j cannot
put the rotated log there, and will keep using the old one -->
<param name="FileNamePattern"
value="/var/log/blah/archive/%d{yyyy}/%d{MM}/file.log.%d{yyyy-MM-dd}.gz"/>
</rollingPolicy>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern"
value="%5p | %-40c{2} | %-4L | %d{yyyy-MM-dd}T%d{HH:mm:ss} | %m%n"/>
</layout>
</appender>
