The point here is that expiration of archived logs isn't done by bro but 
by broctl. Using add-json one thing that might work for you is to redef 
Log::path_json and write out your JSON logs into a different directory. 
For this you could setup a cron job or something to expire files using a 
different interval than you configured for the default logs.
