> CyclicBufferFileAppender
> ------------------------
>
> Key: LBCORE-217
> URL: http://jira.qos.ch/browse/LBCORE-217
> Project: logback-core
> Issue Type: New Feature
> Components: Appender
> Reporter: Pascal Leclercq
> Assignee: Logback dev list
> Attachments: logback-cyclic-appender.zip
>
>
> We mostly use "FileAppender" and/or RollingFileAppender.
> We have a debug level on certain logger just to be sure we'll be able to
> analyse what's goign wrong in case of an error.
> This cause huge amount of logs and slow down our application.
> It would be nice to combine CyclicBufferTracker (like in SMTPAppender) and
> FileAppender to be able to get only the n last lines before and error event
> occurs.
> I create a POC and end up to the conclusion that 50 % performance improvement
> (with the last 1000 lines).
> I would like to send you the POC but I can't upload here.
> Sample conf :
> <configuration>
> <appender name="FILE" class="fr.opensagres.CyclicBufferFileAppender">
> <file>testFile.log</file>
> <append>true</append>
>
> <encoder>
> <pattern>%-4relative [%thread] %-5level %logger{35} - %msg%n</pattern>
> </encoder>
> <cyclicBufferTracker
> class="ch.qos.logback.core.spi.CyclicBufferTrackerImpl">
>
> <bufferSize>1000</bufferSize>
> </cyclicBufferTracker>
> </appender>
> <root level="DEBUG">
> <appender-ref ref="FILE" />
> </root>
> </configuration>
> regards
