我在logback中使用SizeAndTimeBasedRollingPolicy。对于较小的maxFileSize和totalSizeCap值,只有达到totalSizeCap限制时,logback才会删除旧的归档文件。但是,对于totalSizeCap(~5GB)的较大值,它会删除所有已归档的文件。
当我达到totalSizeCap限制时,我只想删除旧的归档文件。我使用的是logback版本1.2.3
这是我正在使用的logback配置。
<appender name="file" class="ch.qos.logback.core.rolling.RollingFileAppender">
<file>${tivo.logpath}/${tivo.logfilename}.log</file>
<rollingPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedRollingPolicy">
<!-- Rollover everyday. If file exceeds 1GB within a day, then file is archived with index starting from 0 -->
<fileNamePattern>${tivo.logpath}/${tivo.logfilename}-%d{yyyyMMdd}-%i.log.gz</fileNamePattern>
<!-- Each file should be at most 1GB -->
<maxFileSize>1GB</maxFileSize>
<!-- Keep maximum 30 days worth of archive files, deleting older ones -->
<maxHistory>30</maxHistory>
<!-- Total size of all archived files is at most 5GB -->
<totalSizeCap>5GB</totalSizeCap>
</rollingPolicy>
<encoder class="ch.qos.logback.core.encoder.LayoutWrappingEncoder">
<layout class="com.tivo.logging.logback.layout.JsonLayout">
<env>${envId}</env>
<datacenter>${dcId}</datacenter>
<serverId>${serverId}</serverId>
<build>${info.properties.buildChange}</build>
<service>${tivo.appname}</service>
</layout>
</encoder>
</appender>

看起来这是logback版本的已知问题&lt; 1.3.0。
Logback: SizeAndTimeBasedRollingPolicy applies totalSizeCap to each day in maxHistory
https://jira.qos.ch/browse/LOGBACK-1361
因此,我们可能需要更新到该版本。
在logback 1.3.0中修复的另一个有趣的错误是: https://jira.qos.ch/browse/LOGBACK-1162
