If you're using a shared web integration across multiple domains — think franchise networks, regional storefronts, or white-label deployments — you've probably wondered which domain a particular session was visiting. Until now, there was no way to tell from the Dash0 UI.
This update surfaces the page.url.domain attribute in three places:
Session list sidebar
The session summary card now shows the domain alongside location and browser info, so you can identify which site a user was on at a glance.
Session detail page
When viewing a full session, the domain appears in the header for quick context as you step through page views and events.
Dashboard filters
A new Domain filter variable is available in both the Overview and Web Vitals dashboards, letting you slice metrics by domain across your entire network.
Also in this update:
- On smaller screens, the session detail header items no longer get squeezed — they now wrap gracefully instead.
