Description

Delete on Rollover is limited to DefaultRolloverStrategy

Why not to add the same feature to the DirectWriteRolloverStrategy  ?

 

Edit :

What i want :

• For Each startup use a log file with the date in its name
• For multiple startup the same day, append log in the same file
• Keep only the last 10 log files

 

If i use DefaultRolloverStrategy, i can keep the last 10 startup in separate file and use DeleteAction to limit the number of log file (for test i use 10, but in prod it's 100 = 10 days * 10 startup)

=> It's bad for me, because i can't have more than 10 startup per day logged.
See the result in ScreenShot-132.png

<RollingFile name="ROCOPYTRACE" filename = "${basePath}/robocopy.log" filePattern = "${basePath}/robocopy-%d{yyyyMMdd}-%i.log">
    <PatternLayout pattern="%msg%n"/>
    <Policies>
        <OnStartupTriggeringPolicy />
    </Policies>
    <DefaultRolloverStrategy max="10">
        <Delete basePath = "${basePath}">
            <IfFileName glob="robocopy-*.log">
                <IfAccumulatedFileCount exceeds="10"/>
            </IfFileName>
        </Delete>
    </DefaultRolloverStrategy>
</RollingFile>

 

If i use DirectWriteRolloverStrategy i can have 1 file per day.
But DeleteAction is never run and i have too many file
See the result in ScreenShot-133.png

 

<RollingFile name="ROCOPYTRACE" filePattern = "${basePath}/robocopy-%d{yyyyMMdd}.log">
    <PatternLayout pattern="%msg%n"/>
    <Policies>
        <OnStartupTriggeringPolicy />
    </Policies>
    <DirectWriteRolloverStrategy>
        <Delete basePath = "${basePath}">
            <IfFileName glob="robocopy-*.log">
                <IfAccumulatedFileCount exceeds="10"/>
            </IfFileName>
        </Delete>
    </DirectWriteRolloverStrategy>
</RollingFile>

 

Il i useTimeBasedTriggeringPolicy or CronTriggeringPolicy and DefaultRolloverStrategy then a run can be split into 2 file.
