One way Monte Carlo can be improved is when rules are breached, it sends an email containing alerts. However, if I want to analyze a particular alert deeper, I have to click on the alert link and further investigate in Monte Carlo's monitor UI. It would be beneficial to include a snapshot of the specific table or error in the alert email for better clarity. There is also an issue with deleting monitors. If my schema or database is active, I can easily delete monitors, but it is quite difficult to remove monitors if the schema no longer exists. I had to use CLI for this use case, but I struggled a lot, so I request that Monte Carlo include this feature in the UI as well for easier deletion. Regarding the features, I can mention that Monte Carlo has just updated the UI. The previous one was user-friendly, and now they have added AI-related elements in the current UI, which is good. However, I still struggle a bit to find things in the current UI, so they can improve that aspect further.
