LogLevel refers to the minimum severity of messages written to the logs. “0” is “almost nothing”. (“1” is normal.) If you have a consistent problem with the UniBilcLogs files growing out of control, you can essentially eliminate them by setting this key to 0. No messages will be written to them except for the startup banner:
[02-15-2019][16:32:07:932] Uniservice initializing, build: 188.8.131.52169
If you experience a problem where logging is necessary, the key can be removed temporarily. It is possible to add this key through an App Layer, the OS layer, or a GPO.
