# TotalDiskSpaceCapacityMetric

A metric that measures disk capacity and usage on the device.

## Declaration

```swift
struct TotalDiskSpaceCapacityMetric
```

## Discussion

Discussion This metric corresponds to the MetricResult.totalDiskSpaceCapacity(_:) case. It appears only in intervalEntries and is not included in state entries. This value is a daily snapshot, not a cumulative sum over the reporting interval. This type replaces the totalDiskSpaceCapacity and totalDiskSpaceUsedSize properties of MXDiskSpaceUsageMetric.
