Logging

debug	NoCheatPlus will print additional debug information in your console and log file if you set this to true.
maxqueuesize	Maximal amount of debug info that can get queued before NoCheatPlus starts to drop them.

Notes:

The queues are used if its scheduled for the primary thread or for an asynchronous task

Backend

Here you can configure the different logging aspects of NoCheatPlus.

prefix	Allows you to set the prefix of the logging messages.
asynchronous	NoCheatPlus will log asynchronously if this is set to true.
filename	Specify an existing folder or a name without extension (must not exist as file), and NCP will create a log file for each run and reload, named by date, all within that folder.
subscriptions	Enabling subscriptions will allow other things (IRC, plugins etc.) but players to receive ingame notifications (permission subscriptions).

Notes

Prefixes can be blank if you only want to see the messages
Color codes are supported in prefixes using &
NoCheatPlus will log in a folder if you change filename: nocheatplus (a new folder "nocheatplus" will be created and logs will be stored in there instead of the single nocheatplus.log file)
