If your Unified Dashboard is not populating with data, make sure 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.
IBM DS4K Required Data Sources
This table lists the probes, QoS metrics, and subkeys or targets that must be activated to populate data in the IBM DS4K dashboard.

IBM DS4K Status Definitions
The IBM DS4K Unified Dashboard displays the status of various components of the disk storage system. This table describes the possible statuses.
Color
Status
Description
Cyan
Unknown
Device status could not be determined.
Cyan
Other
Device status could not be determined.
Green
OK
Device is functioning properly.
Yellow
Degraded
Device is degraded or disabled. This usually means that device performance is not as expected.
Orange
Stressed
Device is experiencing a heavy load.
Red
Predictive failure
Device is in a failure mode that can be predicted by its parent.
Red
Error
Device is in an error state that can be identified by the device or its parent.
Red
Non-recoverable error
Device or its parent has detected an error that requires replacing the device.
Blue
Starting
Device is starting operation.
Blue
Stopping
Device is shutting down.
Blue
Stopped
Device has shut down.
Green
In service
Device is in operation.
Cyan
No contact
Client or parent device cannot contact the device.
Cyan
Lost communication
Client or parent device has lost communication with the device.
Yellow
Aborted
Device has aborted its normal operation.
Cyan
Dormant
Device is in sleep mode.
Red
Supporting entity in error
Child elements are in an error state.
Green
Completed
Device has completed operation.
Storage Array Status
Column
Description
Storage Array
Name of the storage array. Enter text in the filter field in the column header to see only storage array names that contain that text. Click the name of an array to view a Performance Report with performance data for that storage array.
Status
Status of the storage array.
Total Capacity
Total capacity of all disks in the array.
Free Capacity
Number of gigabytes of total capacity not used.
Free Capacity
Gauge displaying the percentage of total capacity not used.
5 to 100 = Green
2 to 4.99 = Orange
0 to 1.99 = Red
Read Hit Ratio
Aggregated ratio of read requests for the array found in cache, as opposed to disk. The higher this number, the better the performance.
90 to 100 = Green
50 to 89.99 = Orange
0 to 49.99 = Red
Write Hit Ratio
Aggregated ratio of write requests for the array found in cache, as opposed to disk. The higher this number, the better the performance.
90 to 100 = Green
50 to 89.99 = Orange
0 to 49.99 = Red
 
Disks Status
Column
Description
Storage Array
Name of the storage array. Enter text in the filter field in the column header to see only storage array names that contain that text.
Disk
Name of the disk. Enter text in the filter field in the column header to see only disk names that contain that text.
Status
Status of the disk.
Read Rate
Rate, in kilobytes per second, at which data is read from disk.
Write Rate
