Igor,

The options that control log file rollover are in your NiFi's
conf/logback.xml file.  Around line 24, you will find a section like the
following for the nifi-app.log:

        <rollingPolicy
class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <!--
              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>./logs/nifi-app_%d{yyyy-MM-dd_HH}.%i.log</fileNamePattern>
            <timeBasedFileNamingAndTriggeringPolicy
class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
                <maxFileSize>100MB</maxFileSize>
            </timeBasedFileNamingAndTriggeringPolicy>
            <!-- keep 30 log files worth of history -->
            <maxHistory>30</maxHistory>
        </rollingPolicy>

The default is not exactly what you want, but you can find an example of a
rolling policy that generates a daily file a bit farther down, around line
64, where the nifi-bootstrap.log is defined:

        <rollingPolicy
class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <!--
              For daily rollover, use 'user_%d.log'.
              For hourly rollover, use 'user_%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>./logs/nifi-bootstrap_%d.log</fileNamePattern>
            <!-- keep 5 log files worth of history -->
            <maxHistory>5</maxHistory>
        </rollingPolicy>
