## AI overview

Vercel Sandbox has added more granular observability with metrics for CPU usage, provisioned memory, data transfer, and running sandboxes and sessions. Metrics can be grouped by sandbox and session, queried through the Vercel CLI, and viewed at team and project levels to connect resource usage with billing.

## Source excerpt

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: Metrics are available at both the team and project level and align directly with how Sandbox usage is billed, so you can attribute costs to specific workloads and catch unexpected usage early. This is useful for tracking agent workloads that create sandboxes at scale, right-sizing sandbox configurations based on actual utilization, and identifying sandboxes with unexpectedly high data transfer. Observability for Sandbox is included on all plans, and manual queries are available on Pro and Enterprise plans. Learn more in the Sandbox documentation. Read more
