Class FileStoreMonitor

java.lang.Object

org.apache.activemq.artemis.core.server.ActiveMQScheduledComponent

org.apache.activemq.artemis.core.server.files.FileStoreMonitor

All Implemented Interfaces:

This will keep a list of fileStores. It will make a comparison on all file stores registered. if any is over the limit, all Callbacks will be called with over.
