Class RetentionScheduler

java.lang.Object

com.nmontytskyi.monitoring.server.scheduler.RetentionScheduler

@Component
public class RetentionScheduler
extends Object

Scheduled component that triggers periodic database cleanup according to the configured data-retention policy.

Reads the retention.enabled, retention.frequency, and retention.time settings at runtime from AppSettingsService and delegates the actual deletion to RetentionService. Running daily by default at 03:00, the scheduler removes metric records, alert events, and report history entries older than their respective retention windows.
