- What is the operational difference between liveness and readiness?
- Why can an HTTP 200 response coexist with broken movie automation?
- What does the lab monitor treat as a successful individual observation?
- Why should production latency thresholds be based on local observations rather than copied from the classroom policy?
- What additional failure paths can a trusted remote probe detect compared with a loopback-only probe?
- Why should monitoring distinguish an indexer failure from complete Radarr HTTP unavailability?
In plain words: Loopback talks only to this computer. Ping 127.0.0.1 to check the local IP stack.
