Vercel Sandbox now supports memory observability
By Steven Van ·
Vercel Sandbox dashboards and the CLI now report memory usage, including P75/P95 stats and a warning line near the memory limit.
Vercel Sandbox observability now includes memory usage alongside CPU and data transfer. The Memory Usage card on the sandbox overview and project/team-level pages reports average, P75, and P95 memory across sandboxes. On the sandbox detail page, charts scale the y-axis to the sandbox's memory limit and add a dashed reference line at 85% of that limit, showing how close a sandbox is running to its ceiling.
The data is also available as the memoryUsedBytes measure on the sandbox usage event in the Observability query builder, for building custom queries and alerts. In the Vercel CLI, the vercel metrics command exposes it under vercel.sandbox.memory_used_bytes: run it in a linked project for project-specific data, or add --all for aggregate data across a team. The announcement says the CLI returns the metric, reporting period, measurement interval, associated project, and a graph with min, max, and average values.
