Hi,
We were using logback's 'ConsoleAppender' for couple of our
projects which was working good.
Recently we are trying to use the 'RollingFileAppender' with
'timeBasedFileNamingAndTriggeringPolicy' and class
"ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP" and facing issues with the
deleting of the older archived files.
Issue is that it doesn't always delete files older than the max history period
when there is considerable time gap between the logging events.
I can see many people raising this issue but couldn't find any information that
this is resolved in any particular release. We are using the 0.9.17 and 0.9.24
versions and this problem occurs in both the versions.
Below are the appender configurations of both the projects with the logback
release versions used.
Project 1: -------------------------------------------------
Uses logback-core 0.9.17
<appender name="ROLLING_FILE"
class="ch.qos.logback.core.rolling.RollingFileAppender">
<file>/var/tmp/GcrDBS/test/dbs.log</file>
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<fileNamePattern>/var/tmp/GcrDBS/test/dbs.log.%d{yyyy-MM-dd_HH-mm}.%i.gz</fileNamePattern>
<timeBasedFileNamingAndTriggeringPolicy
class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
<maxFileSize>500KB</maxFileSize>
</timeBasedFileNamingAndTriggeringPolicy>
<maxHistory>6</maxHistory>
</rollingPolicy>
<layout name="stdLayout" class="ch.qos.logback.classic.PatternLayout">
<Pattern>%d{MMM dd HH:mm:ss.SSS} [%thread] %-5level %logger{36} -
%msg%n</Pattern>
</layout>
</appender>
Project 2: -------------------------------------------------
Uses logback-core 0.9.24
<appender name="ROLLING_FILE"
class="ch.qos.logback.core.rolling.RollingFileAppender">
<file>/var/tmp/GcrWFC/test/dbs.log</file>
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<fileNamePattern>/var/tmp/GcrWFC/test/dbs.log.%d{yyyy-MM-dd_HH-mm}.%i.gz</fileNamePattern>
<timeBasedFileNamingAndTriggeringPolicy
class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
<maxFileSize>100KB</maxFileSize>
</timeBasedFileNamingAndTriggeringPolicy>
<maxHistory>5</maxHistory>
</rollingPolicy>
<encoder>
<pattern>%d{MMM dd HH:mm:ss.SSS} [%thread] %-5level %logger{36} -
%msg%n</pattern>
</encoder>
</appender>
Could someone please let me know if this is fixed in any release? And if so
what is that? Or any work around for this?
Thanks in advance.
