java.lang.Object

com.google.common.util.concurrent.AbstractIdleService

org.graylog.plugins.map.geoip.GeoIpDbFileChangeMonitorService

All Implemented Interfaces:

com.google.common.util.concurrent.Service

@Singleton
public final class GeoIpDbFileChangeMonitorService
extends com.google.common.util.concurrent.AbstractIdleService

A service to check whether the ASN and City MaxMind/IPInfo database files have changed, as well as whether the configuration has changed.

If the database files have changed, a GeoIpDbFileChangedEvent is posted, to which GeoIpProcessor subscribes and reloads the GeoIpResolverEngine.

This service also subscribes to ClusterConfigChangedEvent to update the database files to be monitored, as well as to update the scheduled task (refreshDatabases()) which checks for file changes.
