Vercel tracks the following event types for Observability:
- Edge Requests
- Serverless Functions Invocations
- Edge Functions Invocations
- External API Requests
- Edge Middleware Invocations
Vercel creates one or more of these events each time a request is made to your site. Depending on your application and configuration a single request to Vercel might be:
- 1 edge request event if it's cached.
- 1 Edge Request, 1 Middleware, 1 Function Invocation, and 2 External API calls, for a total of 5 events.
- 1 edge request event if it's a static asset.
Events are tracked on a team level, and so the events are counted across all projects in the team.
You will be charged a base fee when enabling Observability Plus. However, you will only be charged for the remaining time in your billing cycle. For example,
- If ten days remain in your current billing cycle, you will only pay around $3. For every new billing cycle after that, you'll be charged a total of $10 at the beginning of the cycle.
- Events are prorated. This means that if your team incurs 100K events over the included allotment, you would will only pay $0.12 over the base fee. Not $1.20 and the base fee.
- Suppose you disable Observability Plus before the billing cycle ends. In that case, Observability Plus will automatically turn off, we will stop collecting events, and you will lose access to existing data. Also, you cannot export the Observability Plus data for later use.
- Once the billing cycle is over, you will be charged for the events collected prior to disabling. You won't be refunded any amounts already paid.
- Re-enabling Observability Plus before the end of the billing cycle won't cost you another base fee. Instead, the usual base fee of $10 will apply at the beginning of every upcoming billing cycle.
