# Tracing class
The Tracing class exposes the tracing audit interface.
#### Signature:
```typescript
export declare class Tracing
```
## Remarks
You can use `tracing.start` and `tracing.stop` to create a trace file which can be opened in Chrome DevTools or [timeline viewer](https://chromedevtools.github.io/timeline-viewer/).
The constructor for this class is marked as internal. Third-party code should not call the constructor directly or create subclasses that extend the `Tracing` class.
## Example
```ts
await page.tracing.start({path: 'trace.json'});
await page.goto('https://www.google.com');
await page.tracing.stop();
```
## Methods
| Method | Modifiers | Description |
| ---------------------------------------------- | --------- | --------------------------------------------------------- |
| [start(options)](./puppeteer.tracing.start.md) | | Starts a trace for the current page. |
| [stop()](./puppeteer.tracing.stop.md) | | Stops a trace started with the <code>start</code> method. |
