How to enable debug logging per processor vs. system wide

I know there's a way to enable DEBUG logging... thought I saw it somewhere in the docs, but just researched and the Developer's Guide says to use ProcessorLog for DEBUG, but doesn't say how to enable debug logging (or what the logging levels are, how to change logging levels system-wide or per processor).

Any suggestions?

Rick,

The logging is configured in <NIFI_HOME>/conf/logback.xml. In that file you
can specify the fully qualified class name for the processor you want to
enable specific logging for. For instance,

<logger name="org.apache.nifi.processors.standard.GetFile" level="DEBUG"/>

This would enable DEBUG level logging for every GetFile in your flow.
