Notable

🌟 Extraordinary insight into your users and background jobs

Wouldn’t it be great to see when one of your users encounters an error, timeout, or validation failure? Now you can - directly in your admin pages.

Introducing Notable

Notable tracks notable requests and background jobs and stores them in your database. What makes a request or job notable? There are a number of default situations, but ultimately you decide what interests you.

By default, Notable tracks:

• errors
• 404s
• slow requests and jobs
• timeouts
• validation failures
• CSRF failures
• unpermitted parameters
• blocked and throttled requests

You can track custom notes as well.
