attentionThese metrics are still subject to change in the future.
Apart from the usual HTTP specific metrics that k6 already tracks, the browser module tracks the following browser specific performance metrics on top:
| Metric Name | Description |
|---|---|
| browser_dom_content_loaded | Emitted when the page is loaded but scripts have just started to be executed. |
| browser_first_paint | Emitted when the browser renders the first pixel on the page. |
| browser_first_contentful_paint | Emitted when the browser renders the first DOM element on the page, whether that's a text, image or header. |
| browser_first_meaningful_paint | Emitted when the browser renders the main content from above-the-fold that the users are looking for. |
| browser_loaded | Emitted when the page is fully loaded. |
