Posting a bulletin from a script in ExecuteScript

Hello,

I've created a Python script to process flowfiles within an 
ExecuteScript processor following the good example from here:

http://funnifi.blogspot.com/2016/03/executescript-json-to-json-revisited.html

I'm curious if it is possible for my script to post a bulletin to the 
ExecuteScript processor in the event of an error.  Is it possible for a 
script within ExecuteScript to post a bulletin, or are bulletin only 
intended for the nifi framework itself to display errors?

Thank you,
Jake

Jake,

Anything that is logged to a processor's logger will create a bulletin. So from your script, you should be able
to do something like:

log.warn("Something interesting happened")

And that would generate a WARNING level bulletin. The 'Settings' tab of the processor allows you to configure
the minimum bulletin level that will actually show on the UI.

Does this make sense?

Thanks
-Mark

Jake,

log.error("My error message") should cause a bulletin to be posted. If
you have an exception you can pass that in as a second parameter, the
stack trace will be logged (not in the bulletin but in the
logs/nifi-app.log file).


Regards,
Matt
