What is the meaning of "Current player sessions" in the metrics?

I thought “Current player sessions” means how many players are in the game but it isn’t matched.
What does it mean exactly?


Its the number of actual player sessions active.

Player sessions with either ACTIVE status (player is connected to an active game session) or RESERVED status (player has been given a slot in a game session but hasn’t yet connected). This metric can be used with automatic scaling.
