Users in the limited beta of Observability can now view advanced insights for serverless Vercel Functions. Explore low level metrics about function execution, including:

• CPU throttle and memory usage: Understand CPU usage and memory consumption and see if you could benefit from upgrading the function to more resources

• Time to First Byte (TTFB): See how quickly your function responds to requests by sending the first bytes of the response

• Function start type: View cold start and pre-warmed function invocation rates

Observability is in limited beta for current Monitoring users and can be accessed from the new Observability tab in your Vercel projects.
