# init(limitingToCurrentThread:)

Creates a CPU metric that optionally records data only for the current thread.

## Declaration

```swift
init(limitingToCurrentThread limitToCurrentThread: Bool)
```

## Parameters

- `limitToCurrentThread`: A Boolean value that specifies whether to limit the recording of data for this metric to the current thread only.

## Discussion

Discussion If limitToCurrentThread is true, the returned metric only records data related to CPU use on the current thread. In a single-threaded context, a thread-limited metric provides lower variance and greater precision than a whole-process metric.
