Vercel Sandbox now supports memory observability - Vercel

Vercel Sandbox Observability

Vercel Sandbox observability now includes memory usage data.

You can access sandbox memory usage data in the dashboard and through the CLI via the vercel metrics command.

Sandbox Observability Memory in the Dashboard

The Memory Usage card reports average, P75, and P95 memory across your sandboxes, alongside the existing CPU usage and data transfer metrics on the sandbox overview page and the project and team-level pages.

The Memory Usage card in the Sandbox observability dashboard shows usage over time, including metrics for P75, P95, and the average.

On the sandbox detail page, charts are designed to show how close a sandbox is running to its memory ceiling by:

• Automatically scaling the y-axis to the sandbox's memory limit
• Adding a dashed reference line at 85% of that limit

Sandbox memory is also available in the Observability query builder as the memoryUsedBytes measure on the sandbox usage event. You can build custom queries against it and create alerts from the chart.

Sandbox Memory Observability in the CLI

Sandbox observability data is also available through the Vercel CLI via the vercel metrics command under vercel.sandbox.memory_used_bytes. Run the command in a linked project for project-specific data, or append --all to see aggregate data across all projects in your team.

You can access Sandbox memory usage data via the Vercel CLI.

The CLI returns:

• The metric
• The reporting period
• The measurement interval
• The project the sandbox is associated with
• A graph of memory usage, with min, max and avg values
