Uniform Distributed Topic: Monitoring: Durable Subscribers
Use this page to monitor and manage JMS durable subscriptions. From this page, you can view detailed runtime statistics for each durable subscription.
Durable subscribers are persisted to a disk-based file store or a JDBC-accessible database until the message has been delivered to the subscribers or has expired, even if those subscribers are not active when the message is delivered. A durable subscriber registers a durable subscription with a unique identity that is retained by JMS. Subsequent subscriber objects with the same identity resume the subscription in the state it was left by the prior subscriber. If there is no active subscriber for a durable subscription, JMS retains the subscription's messages until they are received by the subscription or until they expire.

Last Messages Received Time in Millis
The time when the last time a subscriber received a message from the subscription. The returned value is a standard java absolute time, which is measured in milliseconds since midnight, January 1, 1970 UTC
This returns the JMS durable subscription boot time if there were no messages that were successfully delivered to any subscriber on this subscription since the subscription was booted. We define the boot time of a durable subscription to be the time the subscription is originally created or recovered during a server reboot or jms migration, which ever is latest.
