Liveness probe — Monitoring and observability
Liveness probe separates process liveness from readiness to receive real traffic. This card shows its role in “Monitoring and observability” and a safe diagnostic path.
Orientation
Liveness probe separates process liveness from readiness to receive real traffic. At this level, separate purpose, input, and visible result. Place Liveness probe within Monitoring and observability before changing settings or files.
Practical use
Keep readiness failing during model loading without repeatedly restarting the slow process. Start in a sandbox with neutral examples. Record the expected state, make one controlled change, and compare status output, application behavior, and logs.
Technical understanding
Liveness probe separates process liveness from readiness to receive real traffic. Technically, Liveness probe connects through interfaces, configuration, state, or dependencies. Trace data from input to output and check versions, permissions, networking, storage, and resources separately.
Operations and debugging
Keep readiness failing during model loading without repeatedly restarting the slow process. In production-like operations, use measurable signals, least privilege, reproducible configuration, and a documented rollback. Preserve evidence, isolate the cause, and verify the correction with the same test.
Exercise
Try it safely
Keep readiness failing during model loading without repeatedly restarting the slow process. Open an isolated test environment and run “curl -s https://example.com/health”. Write down the expected output first, do not alter production data, and record one safe next diagnostic step.

Can you explain the purpose, observable state, and most common failure source of Liveness probe — Monitoring and observability in one sentence each? Which evidence would you preserve before changing anything, and which repeated test would prove that the correction actually worked?
