Hey
@Ashley Zhao!! Thanks for the question - simple but a GOOD one. 🤩
I like to think of monitoring as pointing out an issue, but not enough to really be able to root cause the issue. Think of it as a red/green light - tells you something is going wrong, but doesn’t tell you how to go fix it.
Observability is that ability to trace back the issue to underlying data or model cause!
This is a piece I wrote a while ago that goes deeper on this:
