Jan + all,

Thanks for your help on all this! The script is working great with the
exclusion of SMB logs. Apologies for all the confusion on my side - I'm not
much of a programmer, but use Bro daily as a vital data source at my job.
Anything to enhance the data we get is always good, and JSON makes it much
easier to ingest into other sources.

I've already come across another Bro script that the add-json.bro script
doesn't seem to agree with, but will unload that script as it doesn't
provide much value for my org. I look forward to seeing an updated version
that can handle these stray log files though!

Thanks again!

James Gordon
