Design guidance

SHOULD start with simple availability checks and layer in performance, quality and diagnostic checks.
SHOULD keep basic checks fast (under 1 second) so health checking does not slow the system.
SHOULD run basic checks frequently and comprehensive diagnostics less often.
SHOULD itself be tested.

Quantitative guidance

As stated by the sources; verify before use.

Schedule: basic health every 1 min, detailed every 5 min, comprehensive diagnostics hourly (Ref8.07).
