**Published:** January 30, 2025 | **Authors:** Tobias Lins

> **Note:** This changelog entry is historical. Edge Functions are deprecated for new projects. Use [Vercel Functions](https://vercel.com/docs/functions) with the Node.js runtime and [Fluid compute](https://vercel.com/docs/fluid-compute). Use [Routing Middleware](https://vercel.com/docs/routing-middleware) for request-time routing before a response completes.

Monitoring now includes three new metrics for Edge Functions to provide a comprehensive view of your Edge Function activity and performance:

- [Edge Function Invocations](https://vercel.com/docs/pricing/edge-functions#optimizing-function-invocations)**: **Tracks the total number of times your Edge Functions are invoked, including both successful and errored calls
- [Edge Function Execution Units](https://vercel.com/docs/pricing/edge-functions#managing-execution-units)**: **Measures the CPU time your Edge Functions use, calculated in 50ms increments
- [Fast Origin Transfer](https://vercel.com/docs/pricing/networking#fast-origin-transfer) (Incoming and Outgoing)**: **Track data transfer rates to and from your origin servers

These metrics are available for all [Observability Plus](https://vercel.com/docs/observability#enabling-observability-plus) and [Monitoring](https://vercel.com/docs/observability/monitoring) customers.

Monitoring [recently became part of Observability Plus](https://vercel.com/changelog/monitoring-pricing-reduced-up-to-87).
