The Scheduler Mode indicates the overall rule system used for determining which command should be scheduled next.

Thread Counts shows the number and type of engine process threads that are dedicated to various roles, such as processing incoming blade requests, initiating contact with blades (such as for killing active tasks), and servicing Dashboard and other client requests.

Configs Last Reloaded shows the time and date at which any config file has been reloaded.

Engine Uptime shows the amount of time the engine has been running.

The indicated number licenses are consumed by the Engine, whether the active tasks are running or not. This is important to keep in mind for studios running multiple Engines.
