Good question, though what you have in mind might be real time metrics, not analytics. Even then you might not need real time metrics to know whether your rapid changes are breaking things. An already established dev culture built on CI/CD, actionable health checks, feature flags/toggles, easy release rollbacks in emergencies are what you’d want. This way, your deploys are boring and you can focus on introducing new regressions, uh I mean features, fearlessly. :)
