The Monitor Notes is a file that can be found in Resident Evil: The Umbrella Chronicles.
An internal espionage organization within Umbrella set up to monitor suspicious activity among its employees. They are usually placed throughout the organization and maintain the image of normal employees to help them conduct their activities. There were several placed among the U.B.C.S., one of whom was Nicholai Ginovaef.
Their orders range from spying on fellow employees and destroying evidence to cleanup operations, including assassinations as required. The rewards for successful operations far outweigh the risks, and monitors feel no remorse for selling out or killing their supposed comrades. Rumors are that Colonel Sergei Vladimir is the one pulling the strings behind the group.
