Members

LowPriorityStats
Type: DSTORAGE_PRIORITY_STATS

Statistics of the low priority queues.

NormalPriorityStats
Type: DSTORAGE_PRIORITY_STATS

Statistics of the normal priority queues.

HighPriorityStats
Type: DSTORAGE_PRIORITY_STATS

Statistics of the high priority queues.

RealtimePriorityStats
Type: DSTORAGE_PRIORITY_STATS

Statistics of the realtime priority queues.

CurrentOpenVirtualDiskCount
Type: UINT8

The number of currently open virtual disks (game package, DLC packages, developer scratch, PLS).

MaxOpenVirtualDiskCount
Type: UINT8

The highest number of concurrently opened virtual disks.

CumulativeOpenVirtualDiskCount
Type: UINT32

Cumulative number of opened virtual disks.

PendingStorageRequestCount
Type: UINT32

The number of requests sent by DirectStorage to storage devices that haven't been completed by the hardware yet.

TotalStorageRequestCount
Type: UINT32

The total number of requests sent by DirectStorage to storage devices.

StorageRetries
Type: UINT32

The number of storage device retries.

StorageErrors
Type: UINT32

The number of storage device errors.

PendingDecompressionRequestCount
Type: UINT32

The number of currently pending decompression requests.

TotalDecompressionRequestCount
Type: UINT32

The total number of decompression requests.

DecompressionErrors
Type: UINT32

The number of decompression errors.

StagingBufferStallCount
Type: UINT32

The number of stalls caused by a full staging buffer.

CurrentOpenFileCount
Type: UINT32

The number of currently open files.

MaxOpenFileCount
Type: UINT32

The highest number of concurrently opened files.

CumulativeOpenFileCount
Type: UINT32

Cumulative number of opened files.

CurrentTitleMemoryUsageBytes
Type: UINT32

The current DirectStorage memory footprint (including the staging buffer, etc.).

MaxTitleMemoryUsageBytes
Type: UINT32

The highest DirectStorage memory footprint (including the staging buffer, etc.).

ErrorCount
Type: UINT32

The total number of errors. The error count is incremented every time a request fails for any reason. Sample errors are: reading data from an invalid offset, storage device errors, decompression errors, invalid request parameters, etc.
