Why would one need to check Datadog every morning? Wouldn't alerts fire if there was something to do?
Understanding what your code looks like in production gives you a lot better sense of how to update it, and how to fix it when it does inevitably break. I think having AI checking for you will make this basically impossible, and that probably makes it a pretty bad idea.
I'm not sure I'd do this once a day. I tend to take note of things to build that intuition when I have other reasons to go and look at dashboards, and we have a weekly SLO review as a team, but perhaps there's a place for this in some way.
And for many alerts you need to look at other events around it to properly classify and partially solve them. Due to that you need to give the AI more then just the alerts.
Through I do see a risk similar to wrongly tuned alerts:
Not everything which resolves by itself and can be ignored _in this moment_ is a non issue. It's e.g. pretty common that a system with same rare ignoble warns/errs falls completely flat, when on-boarding a lot of users, introducing a new high load feature, etc. due the exactly the things which you could fully ignore before hand.
