java - How can I set max total disk size for RollingFileAppender? -


i'm using log4j , log4j.extras create rollingfileappender rolls on 2 conditions:

  1. the working filesize exceeds maxfilesize threshold.
  2. the system's date changes.

following this guide, appender needs both timebasedrollingpolicy , sizebasedtriggeringpolicy, example:

<appender name="file_logger" class="org.apache.log4j.rolling.rollingfileappender">     <rollingpolicy class="org.apache.log4j.rolling.timebasedrollingpolicy">         <param name="activefilename" value="/fxh/logs/d3fixfeeds.log" />         <param name="filenamepattern" value="/fxh/logs/d3fixfeeds.%d{hh-mm}.%i.log" />             </rollingpolicy>     <triggeringpolicy         class="org.apache.log4j.rolling.sizebasedtriggeringpolicy">         <param name="maxfilesize" value="50000" /> <!--  in bytes -->     </triggeringpolicy>     <layout class="org.apache.log4j.patternlayout">         <param name="conversionpattern" value="%d{yyyy-mm-dd hh:mm:ss} %-5p - %m%n" />     </layout> </appender>

how can set maximum limit on total disk space of log output? example, our server admin allots 40gb logs application, there anyway specify given dual rolling policies?

so far closest i've found maxbackupindex parameter. can't event work... example, neither of these truncates logs @ 5 files:

<appender name="file_logger" class="org.apache.log4j.rolling.rollingfileappender">     <param name="maxbackupindex" value="5"/>         <rollingpolicy class="org.apache.log4j.rolling.timebasedrollingpolicy">            <param name="activefilename" value="/fxh/logs/d3fixfeeds.log" />            <param name="filenamepattern" value="/fxh/logs/d3fixfeeds.%d{hh-mm}.%i.log" />                 ...

nor

<appender name="file_logger" class="org.apache.log4j.rolling.rollingfileappender">     <rollingpolicy class="org.apache.log4j.rolling.timebasedrollingpolicy">            <param name="activefilename" value="/fxh/logs/d3fixfeeds.log" />            <param name="filenamepattern" value="/fxh/logs/d3fixfeeds.%d{hh-mm}.%i.log" />               <param name="maxbackupindex" value="5"/>                ...

as @arigion says, doesn't log4j can you're asking, fortunately logback can. provides sizeandtimebasedrollingpolicy , totalsizecap allow create logs roll size , time and obey total storage limit, below:

<appender name="file_logger" class="ch.qos.logback.core.rolling.rollingfileappender"> <file>/fxh/logs/d3fixfeeds.log</file> <rollingpolicy class="ch.qos.logback.core.rolling.sizeandtimebasedrollingpolicy">   <!-- rollover daily -->   <filenamepattern>/fxh/logs/d3fixfeeds.%d{hh-mm}.%i.log</filenamepattern>    <maxfilesize>500kb</maxfilesize>        <maxhistory>60</maxhistory>    <totalsizecap>40gb</totalsizecap> </rollingpolicy> <encoder>   <pattern>%d{yyyy-mm-dd hh:mm:ss} %-5p - %m%n</pattern> </encoder> </appender>

this not working example used best guess fields, let me know how goes.

qa guys complained can't automate frontend testing. because our html looks same outside. lazy hack did this <template> <div :role="$options.name"> ... </div> </template> <script> export default { name: 'vmcomponentname' } </script> which takes name script , applies html. in browser get: <div role="vmcomponentname"> ... </div> line :role="$options.name" goes in every component. is there dry er solutions? please share. additional details i'll explain in details looking for. imagine have vmusercreate form creates user. test case can create user . to automatically test without role, have use following selector: .wrapper > .wrapper > .wrapper > .submit-button the test extremely brittle (will break lot). if use roles can use [role="vmusercreateform"] .submit-button selector. many folds less brittle. so basically, i'm ...
