Blog: Meet Horizon UI · 13/17: Platform & Cluster Introspection

This is the thirteenth post in the Meet Horizon UI series, and the last stop in Act 3 — operate it . The earlier operate posts were about acting on the backend — alarms, runtime rules, the live debugger, cross-layer inspect. This one turns the lens around onto the backend itself : is it healthy, how is it configured, and how long does it keep your data? Three read-only surfaces under Platform monitoring answer exactly those questions — no knobs, just the facts you need when you’re triaging.
