4. Monitoring, Logging and Statistics

balancerHealthMonitor

Health monitor for a {@link LoadBalancingInterceptor} {@link Cluster}. Periodically checks the health of all clusters registered on the router and updates each {@link Node}'s status accordingly. When initialized, it schedules a task to call each {@link Node}'s health endpoint and marks nodes as {@link Status#UP} or {@link Status#DOWN} based on the HTTP response. This ensures the load balancer always has up-to-date status for routing decisions.
