Fleet Usage Metrics for Multi-session Fleets

The following are fleet usage metrics for multi-session fleets.

Metric Description Dimensions Statistics Units
CapacityUtilization

The percentage of sessions in a fleet that are being used, using the following formula.

CapacityUtilization = (ActiveUserSessionCapacity / ActualUserSessionCapacity) * 100

Monitoring this metric helps with decisions about increasing or decreasing the value of a fleet's desired capacity.

[Fleet] Average, Minimum, Maximum Percent
ActualUserSessionCapacity

The total number of session slots that are available for streaming or are currently streaming.

ActualUserSessionCapacity = AvailableUserSessionCapacity + ActiveUserSessionCapacity
[Fleet] Average, Minimum, Maximum Count
AvailableUserSessionCapacity

The number of idle session slots currently available for user sessions.

AvailableUserSessionCapacity = ActualUserSessionCapacity - ActiveUserSessions
[Fleet] Average, Minimum, Maximum Count
DesiredUserSessionCapacity

The total number of session slots that are either running or pending. This represents the total number of concurrent streaming sessions your fleet can support in a steady state.

DesiredUserSessionCapacity = ActualUserSessionCapacity + PendingUserSessionCapacity
[Fleet] Average, Minimum, Maximum Count
ActiveUserSessionCapacity

The number of user sessions currently being used for streaming sessions.

[Fleet] Average, Minimum, Maximum Count
PendingUserSessionCapacity

The number of session slots being provisioned by WorkSpaces Applications. Represents the additional number of streaming sessions the fleet can support after provisioning is complete. When provisioning starts, it usually takes 10-20 minutes for an instance to become available for streaming.

[Fleet] Average, Minimum, Maximum Count
RunningUserSessionCapacity

The total number of session slots currently that are available for streaming or are currently streaming. Represents the number of concurrent streaming sessions that can be supported by the fleet in its current state.

This metric is provided for Always-On fleets only, and has the same value as the ActualUserSessionCapacity metric.
