Beyond monitoring MySQL’s performance metrics, you can also write custom SQL to monitor data inside MySQL (via Categraf’s mysql plugin). This is typically useful in two scenarios:

- Monitoring business data — this scenario is extremely broad, such as monitoring order data, user data, etc. It is often overlooked but can deliver outstanding results
