Aldrin Piri updated MINIFI-390:
-------------------------------
Description:
At high rates of logging, the compression of archived log files configured in
logback can cause an unbounded growth of file size despite totalSizeCap.
The issue can be seen in the following APP appender and triggered with a
root-level of DEBUG.
{code}
<appender name="APP_FILE"
class="ch.qos.logback.core.rolling.RollingFileAppender">
<file>${org.apache.nifi.minifi.bootstrap.config.log.dir}/minifi-app.log</file>
<rollingPolicy
class="ch.qos.logback.core.rolling.SizeAndTimeBasedRollingPolicy">
<!--
For daily rollover, use 'app_%d.log'.
For hourly rollover, use 'app_%d{yyyy-MM-dd_HH}.log'.
To GZIP rolled files, replace '.log' with '.log.gz'.
To ZIP rolled files, replace '.log' with '.log.zip'.
-->
<fileNamePattern>${org.apache.nifi.minifi.bootstrap.config.log.dir}/minifi-app_%d{yyyy-MM-dd_HH}.%i.log</fileNamePattern>
<!-- Keep 10 rolling periods worth of log files-->
<maxHistory>1</maxHistory>
<!-- Max size each log file will be-->
<maxFileSize>10MB</maxFileSize>
<!-- Provide a cap of 10 MB across all archive files -->
<totalSizeCap>1000MB</totalSizeCap>
</rollingPolicy>
<immediateFlush>true</immediateFlush>
<encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
<pattern>%date %level [%thread] %logger{40} %msg%n</pattern>
</encoder>
</appender>
{code}
This seems to be related to https://jira.qos.ch/browse/LOGBACK-1162 which is
currently in progress. We should monitor this progression and incorporate the
updated dependency when released. The workaround for those environments
experiencing this is to disable archiving (by removing the .gz from the
filename pattern).
