Uniform Distributed Topic: Monitoring: Durable Subscribers

Column Display     

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.

Name	Description
Client ID	A unique client identifier for this durable subscriber. Note: The client ID is not necessarily equivalent to the WebLogic Server username; that is, a name used to authenticate a user in the WebLogic security realm. You can set the client ID to the WebLogic Server username if it is appropriate for your JMS application. MBean Attribute: JMSDurableSubscriberRuntimeMBean.ClientID
Client ID Policy	The policy for the client identifier for this durable subscriber. Note: The client ID policy is either Restricted or Unrestricted. MBean Attribute: JMSDurableSubscriberRuntimeMBean.ClientIDPolicy
Subscription Name	The subscription name for this durable subscriber. This name must be unique for each client ID. Valid durable subscription names cannot include the following characters: comma ",", equals "=", colon ":", asterisk "*", percent "%", or question mark"?". MBean Attribute: JMSDurableSubscriberRuntimeMBean.SubscriptionName
Active	Indicates whether this subscription is being used by a durable subscriber. MBean Attribute: JMSDurableSubscriberRuntimeMBean.Active
Messages Current Count	The number of messages still available by this durable subscriber. MBean Attribute: JMSDurableSubscriberRuntimeMBean.MessagesCurrentCount
Messages Pending Count	The number of messages pending (uncommitted and unacknowledged) by this durable subscriber. MBean Attribute: JMSDurableSubscriberRuntimeMBean.MessagesPendingCount
Bytes Current Count	The number of bytes received by this durable subscriber. MBean Attribute: JMSDurableSubscriberRuntimeMBean.BytesCurrentCount
Bytes Pending Count	The number of bytes pending by this durable subscriber. MBean Attribute: JMSDurableSubscriberRuntimeMBean.BytesPendingCount
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. MBean Attribute: JMSDurableSubscriberRuntimeMBean.LastMessagesReceivedTime
No Local Messages	Specifies whether this durable subscriber receives local messages that it has published. To prevent this, set the noLocal parameter to true. MBean Attribute: JMSDurableSubscriberRuntimeMBean.NoLocal
Selector	The message selector defined for this durable subscriber. MBean Attribute: JMSDurableSubscriberRuntimeMBean.Selector
Subscribers Current Count	The number of subscribers that currently share this subscription. MBean Attribute: JMSDurableSubscriberRuntimeMBean.SubscribersCurrentCount
Subscribers High Count	The highest number of subscribers that have shared this subscription at the same time since the creation or the last reboot of the subscription, which ever is later. MBean Attribute: JMSDurableSubscriberRuntimeMBean.SubscribersHighCount
Subscribers Total Count	The total number of subscribers that have accessed this subscription since the creation or the last reboot of the subscription, whichever is later. MBean Attribute: JMSDurableSubscriberRuntimeMBean.SubscribersTotalCount
Subscription Sharing Policy	The SubscriptionSharingPolicy on this subscriber. MBean Attribute: JMSDurableSubscriberRuntimeMBean.SubscriptionSharingPolicy
