The Vercel Observability dashboard now includes a dedicated view for middleware, showing invocation counts and performance metrics.

Observability Plus users get additional insights and tooling:

• Analyze invocations by request path, matched against your middleware config

• Break down middleware actions by type (e.g., redirect, rewrite)

• View rewrite targets and frequency

• Query middleware invocations using the query builder
