Periodic Status Reporters
You can set up Periodic Status Reporters to periodically report the status of your dataflow. The query executes at configurable intervals and the results are reported using the configured implementation. Configure the Reporters in the bootstrap.conf file, using the "nifi.minifi.status.reporter.components" key followed by the full path name of the desired Reporter implementation to run. Use a comma separated list to define more than one Reporter implementation. For example:
nifi.minifi.status.reporter.components=org.apache.nifi.minifi.bootstrap.status.reporters.StatusLogger
