Name of the GameLift-defined metric that is used to trigger an adjustment.
ActivatingGameSessions – number of game sessions in the process of being
created (game session status = ACTIVATING). ActiveGameSessions – number of game sessions currently running (game session status = ACTIVE). CurrentPlayerSessions – number of active or reserved player sessions (player session status = ACTIVE or RESERVED). AvailablePlayerSessions – number of player session slots currently available in active game sessions across the fleet, calculated by subtracting a game session's current player session count from its maximum player session count. This number does include game sessions that are not currently accepting players (game session PlayerSessionCreationPolicy = DENY_ALL).
ActiveInstances – number of instances currently running a game session. IdleInstances – number of instances not currently running a game session.
