log4j2 Delete on Rollover - log4j2

Question

I read the official document of log4j2 and get a question about RollingFileAppender.
That's what the document says:
Below is a sample configuration that uses a RollingFileAppender with both the time and size based triggering policies, will create up to 100 archives on the same day (1-100) that are stored in a directory based on the current year and month, and will compress each archive using gzip and will roll every hour. During every rollover, this configuration will delete files that match "/app-.log.gz" and are 30 days old or older, but keep the most recent 100 GB or the most recent 10 files, whichever comes first.
<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="warn" name="MyApp" packages="">
<Properties>
<Property name="baseDir">logs</Property>
</Properties>
<Appenders>
<RollingFile name="RollingFile" fileName="${baseDir}/app.log"
filePattern="${baseDir}/$${date:yyyy-MM}/app-%d{yyyy-MM-dd-HH}-%i.log.gz">
<PatternLayout pattern="%d %p %c{1.} [%t] %m%n" />
<Policies>
<TimeBasedTriggeringPolicy />
<SizeBasedTriggeringPolicy size="250 MB"/>
</Policies>
<DefaultRolloverStrategy max="100">
<!--
Nested conditions: the inner condition is only evaluated on files
for which the outer conditions are true.
-->
<Delete basePath="${baseDir}" maxDepth="2">
<IfFileName glob="*/app-*.log.gz">
<IfLastModified age="30d">
<IfAny>
<IfAccumulatedFileSize exceeds="100 GB" />
<IfAccumulatedFileCount exceeds="10" />
</IfAny>
</IfLastModified>
</IfFileName>
</Delete>
</DefaultRolloverStrategy>
</RollingFile>
</Appenders>
<Loggers>
<Root level="error">
<AppenderRef ref="RollingFile"/>
</Root>
</Loggers>
</Configuration>
I think this configuration will create up to 100 archives on the same hour of the day, not 100 archives on the same day, can anybody who give me a hand? Thanks!

Answer 1

Yes, it will keep up to 100 files in the hour but in reality it will never get that high since it is only keeping a maximum of 10 files overall.
