If your Unified Dashboard is not populating with data, verify all required data sources for the Unified Dashboard are enabled. The required probe must be deployed and must be configured so that required QoS metrics and subkeys or targets are activated. For more information, see the help topic on required data sources for the Unified Dashboard.

Auto Scaling Group Summary
This table displays information about the health and performance of the AWS Auto Scaling groups.
Column
Description
Desired Capacity
The number of instances that the Auto Scaling group maintains.
Minimum Size
The minimum size of the Auto Scaling group.
Maximum Size
The maximum size of the Auto Scaling group.
Total Instances
The total number of instances (
in service
,
pending
, and
terminating
) in the Auto Scaling group.
In Service Instances
The number of instances that are currently
executing
in the Auto Scaling group.
Pending Instances
The number of instances that are currently pending in the Auto Scaling group. Amazon defines a pending instance as
not yet in service
.
Standby Instances
The number of instances that are in Standby state in the Auto Scaling group. Amazon defines an instances as standby when the instance is
executing, but is not actively in service
.
Terminating Instances
The number of instances that are currently
terminating
in the Auto Scaling group.
Auto Scaling Health Summary
This table displays information about the health of the AWS Auto Scaling service.
Column
Description
Status Check Failed
The operational status of the service as a combination of the Status Check Failed Instance and Status Check Failed System monitors. 
Status Check Failed Instance
The operational status of the instance.
Status Check Failed System
The operational status of the system.
Auto Scaling Performance Summary
This table displays information about the performance of the AWS Auto Scaling service.
Column
Description
CPU Utilization
The percentage of allocated EC2 compute units that are currently in use on the instance. You can use the information to identify the processing power required to execute an application on the selected instance.
Disk Read Ops
The number of completed read operations from all ephemeral disks available to the instance. You can use the information to identify the rate at which an application reads from a disk.
Disk Write Ops
The number of completed write operations to all ephemeral disks available to the instance. You can use the information to identify the rate at which an application writes to a disk.
Disk Read Bytes
The number of bytes read from all ephemeral disks available to the instance. You can use the information to determine the volume of data that the application reads from the hard disk of the instance.
Disk Write Bytes
The number of bytes written to all ephemeral disks available to the instance. You can use the information to determine the volume of data that the application writes to the hard disk of the instance.
Network In
The number of bytes received on all network interfaces by the instance. You can use the information to identify the volume of incoming network traffic to an application on the instance.
Network Out
The number of bytes sent on all network interfaces by the instance. You can use the information to identify the volume of outgoing network traffic from an application on the instance.
