java - How to keep rolling log file as per file size? -


i working on project in logging bunch of stuff in file , want make sure log file getting rolled fixed limit file reached. have below logback.xml file looks file size not working. see file size 793m limit have 100m

<configuration>     <appender name="file" class="ch.qos.logback.core.fileappender">         <file>process.log</file>         <triggeringpolicy             class="ch.qos.logback.core.rolling.sizebasedtriggeringpolicy">             <maxfilesize>100mb</maxfilesize>         </triggeringpolicy>         <rollingpolicy class="ch.qos.logback.core.rolling.fixedwindowrollingpolicy">             <filenamepattern>process%i.log</filenamepattern>             <minindex>1</minindex>             <maxindex>9</maxindex>         </rollingpolicy>         <encoder>             <pattern>%date %level [%thread] %msg%n</pattern>             <!-- improves logging throughput -->             <immediateflush>true</immediateflush>         </encoder>     </appender>      <appender name="stdout" class="ch.qos.logback.core.consoleappender">         <!-- encoders assigned type ch.qos.logback.classic.encoder.patternlayoutencoder              default -->         <encoder>             <pattern>%d{hh:mm:ss.sss} [%thread] %-5level %logger{36} - %msg%n             </pattern>         </encoder>     </appender>      <root level="info">         <appender-ref ref="file" />         <appender-ref ref="stdout" />     </root> </configuration>

what wrong doing here? , best policy should follow in production in terms of logging? logging bunch of stuff in file , don't want fill disk log file.

instead of fileappender, should using rollingfileappender. see: http://logback.qos.ch/manual/appenders.html

you specifying settings/properties intended used rollingfileappender , ignored fileappender.

for example usage , configuration, refer link: http://examples.javacodegeeks.com/enterprise-java/logback/logback-rollingfileappender-example/

sample logback.xml using rollingfileappender , consoleappender. rollingfileappender both size , time based:

    <?xml version="1.0" encoding="utf-8"?>     <configuration scan="true">         <appender name="consoleappender" class="ch.qos.logback.core.consoleappender">             <encoder>                 <charset>utf-8</charset>                 <pattern>%d %-4relative [%thread] %-5level %logger{35} - %msg%n</pattern>             </encoder>         </appender>          <appender name="file" class="ch.qos.logback.core.rolling.rollingfileappender">             <file>/srv/logs/application.log</file>              <rollingpolicy class="ch.qos.logback.core.rolling.timebasedrollingpolicy">                 <filenamepattern>logfile.%d{yyyy-mm-dd}.log</filenamepattern>                 <maxhistory>30</maxhistory>              </rollingpolicy>              <triggeringpolicy class="ch.qos.logback.core.rolling.sizebasedtriggeringpolicy">                 <maxfilesize>5mb</maxfilesize>             </triggeringpolicy>              <encoder>                 <charset>utf-8</charset>                 <pattern>%d %-4relative [%thread] %-5level %logger{35} - %msg%n</pattern>             </encoder>         </appender>          <root level="debug">             <appender-ref ref="consoleappender" />             <appender-ref ref="file"/>         </root>     </configuration>
