The Observability tab is a powerful tool for reviewing and diagnosing ISR-related usage. For example, when using Next.js, you can view all paths and see detailed metrics on reads and writes:
However, different frameworks interact with ISR in uniquely, which may affect the level of information displayed in the Observability tab. For example, Nuxt.js only uses a single nitro function, so Vercel can only display this on the dashboard.
To enable full ISR Observability across frameworks, framework developers can integrate the Vercel Build Output API. If your framework doesn't yet support this functionality, consider reaching out to the framework's maintainers to request this enhancement. Collaboration between framework developers and the community can help ensure everyone benefits from more comprehensive observability features.
