Vercel Sandbox observability now includes detailed resource metrics, giving you deeper visibility into how your sandboxes consume compute and networking.

From the Observability tab in your dashboard, you can now monitor:

Active CPU and CPU usage: Measures when your code actively uses the CPU. Active CPU is measured in core-hours and time spent waiting on I/O, such as network requests or model calls, is not billed

Provisioned Memory: Memory allocated to your sandboxes multiplied by runtime, measured in GB-hours

Data Transfer: Total data transferred in and out of your sandboxes, including package downloads and API calls

Running sandboxes and sessions: How many sandboxes are running at any give time, and when sessions are stopped or started

Each metric can be grouped by Sandbox Name and Sandbox Session ID, so you can drill down from aggregate usage to the individual sandbox responsible.

You can also query and visualize metrics via the Vercel CLI:
