AppStream 2.0 Metrics and Dimensions
Amazon AppStream 2.0 sends the following metrics and dimension information to Amazon CloudWatch.
All of the following metrics except InsufficientConcurrencyLimitError
apply to Always-On and On-Demand fleets. The only metrics that apply to Elastic fleets
are InUseCapacity
and InsufficientCapacityError
.
AppStream 2.0 sends metrics to CloudWatch one time every minute. The AWS/AppStream
namespace includes the following metrics.
Fleet Usage Metrics for Single-session Fleets
Metric | Description |
---|---|
ActualCapacity |
The total number of instances that are available for streaming or are currently streaming.
Units: Count Valid statistics: Average, Minimum, Maximum |
AvailableCapacity
|
The number of idle instances currently available for user sessions.
Units: Count Valid statistics: Average, Minimum, Maximum |
CapacityUtilization |
The percentage of instances in a fleet that are being used, using the following formula.
Monitoring this metric helps with decisions about increasing or decreasing the value of a fleet's desired capacity. Units: Percent Valid statistics: Average, Minimum, Maximum |
DesiredCapacity
|
The total number of instances that are either running or pending. This represents the total number of concurrent streaming sessions your fleet can support in a steady state.
Units: Count Valid statistics: Average, Minimum, Maximum |
InUseCapacity
|
The number of instances currently being used for streaming sessions.
One Units: Count Valid statistics: Average, Minimum, Maximum |
PendingCapacity
|
The number of instances being provisioned by AppStream 2.0. 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. Units: Count Valid statistics: Average, Minimum, Maximum |
RunningCapacity |
The total number of instances currently running. 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 Units: Count Valid statistics: Average, Minimum, Maximum |
InsufficientCapacityError
|
The number of session requests rejected due to lack of capacity. You can set alarms to use this metric to be notified of users waiting for streaming sessions. Units: Count Valid statistics: Average, Minimum, Maximum, Sum |
InsufficientConcurrencyLimitError
|
The number of Elastic fleet session requests rejected due to reaching max concurrent streaming capacity. You can set alarms to use this metric to be notified of users waiting for streaming sessions. Units: Count Valid statistics: Average, Minimum, Maximum, Sum |
Fleet Usage Metrics for Multi-session Fleets
Metric | Description |
---|---|
CapacityUtilization |
The percentage of sessions in a fleet that are being used, using the following formula.
Monitoring this metric helps with decisions about increasing or decreasing the value of a fleet's desired capacity. Units: Percent Valid statistics: Average, Minimum, Maximum |
ActualUserSessionCapacity |
The total number of session slots that are available for streaming or are currently streaming.
Units: Count Valid statistics: Average, Minimum, Maximum |
AvailableUserSessionCapacity
|
The number of idle session slots currently available for user sessions.
Units: Count Valid statistics: Average, Minimum, Maximum |
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.
Units: Count Valid statistics: Average, Minimum, Maximum |
ActiveUserSessionCapacity |
The number of user sessions currently being used for streaming sessions. Units: Count Valid statistics: Average, Minimum, Maximum |
PendingUserSessionCapacity
|
The number of session slots being provisioned by AppStream 2.0. 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. Units: Count Valid statistics: Average, Minimum, Maximum |
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 Units: Count Valid statistics: Average, Minimum, Maximum |
Instance and Session Performance Metrics for Multi-session Fleets
Metric | Description |
---|---|
CpuUtilizationInstance |
The percentage of allocated compute units that are currently in use on the instance. Units: Percent |
MemoryUtilizationInstance |
The percentage of allocated physical memoty units that are currently in use on the instance. Units: Percent |
PagingFileUtilizationInstance
|
The percentage of the paging file that is currently in use to extend the Memory (RAM) capacity. Units: Percent |
DiskUtilizationInstance
|
The percentage of disk units that are currently in use to run programs and carry out tasks on the instance. Units: Percent |
CpuUtilizationSession |
The percentage of allocated compute units that are currently in use by the session. Units: Percent |
MemoryUtilizationSession
|
The percentage of allocated physical memoty units that are currently in use by the session. Units: Percent |
