feat: add health check probes for k8s liveness and readiness #2331

vimalk78 · 2025-10-06T06:35:38Z

Implement health probe endpoints following k8s best practices:

Add LiveChecker and ReadyChecker interfaces to service framework
Implement IsLive() and IsReady() methods in PowerMonitor using atomic operations
Create HealthProbe service with /probe/livez and /probe/readyz endpoints
Update K8s daemonset to use new health endpoints instead of /metrics
unit tests for health check
