Class MetricsPollingScheduler

java.lang.Object

com.nmontytskyi.monitoring.server.polling.MetricsPollingScheduler

@Component
@ConditionalOnProperty(prefix="monitoring.polling",
                       name="enabled",
                       havingValue="true",
                       matchIfMissing=true)
public class MetricsPollingScheduler
extends Object

Scheduled component that periodically pulls health and JVM metrics from each registered service's Spring Boot Actuator endpoints.

Runs every monitoring.polling.interval-seconds (default: 30 s). For each active service it calls ActuatorClient to fetch /actuator/health and /actuator/metrics, then converts the responses into MetricSnapshotRequest objects and delegates persistence to MetricsPersistenceService.

This pull-based collection complements the push-based collection performed by the monitoring starter's AOP aspects for per-request response-time data.
