Hi I am using Log4j for logging. Below is my configuration.
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">
<log4j:configuration debug="true"
xmlns:log4j='http://jakarta.apache.org/log4j/'>
<appender name="FileAppender_Comp3" class="org.apache.log4j.rolling.RollingFileAppender">
<rollingPolicy name="file" class="org.apache.log4j.rolling.TimeBasedRollingPolicy">
<param name="FileNamePattern" value="log/Comp3_%d{dd-MM-yyyy HH-mm-ss}.log" />
</rollingPolicy>
<triggeringPolicy class="org.apache.log4j.rolling.SizeBasedTriggeringPolicy">
<param name="MaxFileSize" value="3kb"/>
</triggeringPolicy>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%d %5p [%t] %c (%F:%L) - %m%n"/>
</layout>
</appender>
But when I am running file it is throwing below error.
log4j:WARN Failed to set property [maxFileSize] to value "3kb".
How can I fix this. Please help me.
If you are using Log4j 2, you can specify the size in KB or MB.
Relevant XML below.
<Policies>
<!-- Starts a new log on tomcat start -->
<OnStartupTriggeringPolicy />
<!-- Starts a new file when size reaches threshold -->
<SizeBasedTriggeringPolicy size="10 MB" />
<!-- causes a rollover once the date/time pattern no longer
applies to the active file -->
<TimeBasedTriggeringPolicy />
</Policies
Please see https://logging.apache.org/log4j/2.x/manual/appenders.html for more details.
