CM/CFM: ControllerStatusReportingTask

Hi,

 

I am using CM 6.3.1 with CFM. As I am exploring NIFI -> ControllerStatusReportingTask and I wanted to log the output to a log file. I realised the logback.xml is auto generated by Cloudera Manager, how am I going to add customize logback configuration for the ControllerStatusReportingTask into the logback.xml?

 

From the CM, there is a NIFI Node XML Override (logback_safety_valve). Should I use this?

It seems that, the input require a complete logback XML file. Just wanted to be sure of the approach as I will be upgrading on my production system.

You are absolutely correct, the Cloudera Manager configuration property within NiFi configurations fro logback.xml does require you to input the entire logbck.xml and then add your modifications.

Adding a new logger for the ControllerStatusReportingTask would require adding a logger like this:

<logger name="org.apache.nifi.controller.ControllerStatusReportingTask" level="DEBUG"/>

You can add this logger in line along with other loggers already in the logback.xml

The result would be all logging from this class at a DEBUG level and below would go in to the nifi-app.log.

You could optionally add an additional appender (NiFi has three existing appender now for the nifi-app.log, nifi-user.log and nifi-bootstrap.log files).  You can copy and modify one of those and the your logger would need to look like this:

  <logger name="org.apache.nifi.controller.ControllerStatusReportingTask" level="DEBUG" additivity="false">
    <appender-ref ref="NEW_APPENDER"/>
  </logger>
