class name: org.apache.nifi.minifi.bootstrap.status.reporters.StatusLogger

The Periodic Status Reporter logs the results of the query to the logs. By default it is logged to the minifi-bootstrap.log but you can modify logback.xml to log to an alternate file and location.

Example bootstrap.conf configuration:

# The FlowStatus query to submit to the MiNiFi instance
nifi.minifi.status.reporter.log.query=instance:health,bulletins
# The log level at which the status will be logged
nifi.minifi.status.reporter.log.level=INFO
# The period (in milliseconds) at which to log the status
nifi.minifi.status.reporter.log.period=60000

Example logback.xml configuration to output the status to its own rolling log file:

<appender name="STATUS_LOG_FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
    <file>logs/minifi-status.log</file>
    <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/minifi-status_%d.log</fileNamePattern>
        <!-- keep 5 log files worth of history -->
        <maxHistory>5</maxHistory>
    </rollingPolicy>
    <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
        <pattern>%date %level [%thread] %logger{40} %msg%n</pattern>
    </encoder>
</appender>
