A CPU that had thermally throttled (sysfs thermal_throttle counter >
0) still reported status "OK" everywhere: dmidecode-derived CPU status
only distinguishes populated/enabled/disabled and never looked at the
throttle flag the collector already recorded next to it, and neither
SAT path meant to catch this actually could:
- The routine "cpu" SAT pack (RunCPUAcceptancePack) only checked
lscpu/sensors/stress-ng exit codes — stress-ng exits 0 whether or
not the CPU throttled while running it, so an 89°C/throttled CPU
right after a "successful" run still showed cpu:all as OK in
component-status.json.
- The more thorough platform-stress test already detected throttling
and fan-spindown correctly, but wrote its verdict as "Overall: FAIL
— ..." with no "=", which parseSATKV can't parse — so even a real
detected throttle event never reached the component-status DB.
Fixes:
- cpu_telemetry.go: escalate a CPU's status to Warning (only-escalate,
same severity ranking already used elsewhere) when Throttled is set.
- sat.go: add a before/after thermal-throttle-counter check job around
the "cpu" pack's stress-ng run, so a throttle event during the run
fails that job and (via the existing FAILED->Warning DB mapping)
flips cpu:all to Warning.
- platform_stress.go: emit a machine-readable overall_status= line
alongside the human-readable verdict so platform-stress results
actually reach ApplySATResultToDB.
