3.2.7.1. JBossAS5 - Queue Service
Overview
Table 3.128. Overview
| Description: | a JMS queue |
| Singleton: | no |
| Plugin: | JBossAS5 |
Note
The message counter metrics will not be collected by default. In order for these metrics to be collected for all Topics and Queues for a given application server instance, go to the instance's JMX Console, and invoke the {{enableMessageCounters}} operation on the {{jboss.messaging:service=ServerPeer}} MBean. To ensure the message counters are still enabled when the application server is restarted, edit that instance's {{deploy/messaging/messaging-service.xml}} file and set the {{EnableMessageCounters}} attribute to "true".
Child Resource Types
none

| Custom Properties | Maps a list of custom property names to the the fully qualified class names of the org.rhq.plugins.jbossas5.adapter.api.PropertyAdapter implementations that should be used for those properties. | no | customProperties |
| Component Type | yes | componentType | |
| Component Subtype | yes | componentSubtype | |
| Component Name | yes | componentName | |
| Template Name | yes | templateName | |
| Component Name Property | The name of the Resource configuration property whose value should be used as the underlying ManagedComponent name when creating a new Resource of this type. | yes | componentNameProperty |

Metrics
Table 3.130. Metrics
| Name | Type | Description | Internal Name |
|---|---|---|---|
| Run State | trait | Run State | runState |
| Created Programmatically | trait | Was this queue created programmatically? If Yes, the queue will not survive a restart of the application server. If No, the queue was created via a deployment XML file. | createdProgrammatically |
| Message Counter History Day Limit | trait | This queue's message counter history day limit - <0: unlimited, =0: history disabled, >0: maximum day count | messageCounterHistoryDayLimit |
| Consumer Count | measurement | The number of consumers on the queue | consumerCount |
| Delivering Count | measurement | The number of messages currently being delivered | deliveringCount |
| Message Count | measurement | The number of messages in the queue | messageCount |
| Scheduled Message Count | measurement | The number of scheduled messages in the queue | scheduledMessageCount |
| Count | measurement | The total message count since startup or last counter reset | messageStatistics.count |
| Count Delta | measurement | The message count delta since last method call | messageStatistics.countDelta |
| Depth | measurement | The current message count of pending messages within the queue waiting for dispatch | messageStatistics.depth |
| Depth Delta | measurement | The message count delta of pending messages since last method call | messageStatistics.depthDelta |
| Time Last Update | measurement | The timestamp of the last message add | messageStatistics.timeLastUpdate |
| Clustered | trait | True if this queue is clustered, false otherwise | clustered |
Note
You must use the internal name to reference Traits in Dynamic Group Definition expressions.
Configuration Properties
Table 3.131.
| Name | Description | Required | Internal Name |
|---|---|---|---|
| Name | The name of this queue (e.g. 'MyQueue'). | yes | name |
| JNDI Name | This queue's JNDI name (e.g. '/queue/MyQueue'). | yes | JNDIName |
| Clustered | Is this queue clustered? For an existing queue, this property is read-only. If not specified when creating a new queue, the default value is false. | no | clustered |
| Down Cache Size | When paging messages to storage from a subscription, they first go into a "Down Cache" before being written to storage. This enables the write to occur as a single operation, thus aiding performance. This setting determines the maximum number of messages that the Down Cache will hold before they are flushed to storage. Updates to this property will not go into effect until the queue has been restarted. The default value is 2000. | no | downCacheSize |
| Full Size | The maximum number of messages for the queue held in memory at any one time. The actual queue can hold many more messages than this, but these are paged to and from storage as necessary, as messages are added or consumed. Updates to this property will not go into effect until the queue has been restarted. The default value is 200000. | no | fullSize |
| Max Delivery Attempts | The number of delivery attempts before a message to a subscriber of this queue is moved to the DLQ. The default value is 10. A value of -1 indicates the default value should be used. | no | maxDeliveryAttempts |
| Max Size | The maximum number of messages this queue can hold before they are dropped. A value of -1 means there is no maximum. The default value is -1. | no | maxSize |
| Page Size | When loading messages from a subscription, this is the maximum number of messages to pre-load in one operation. Must be less than Full Size and greater than or equal to Down Cache Size. Updates to this property will not go into effect until the queue has been restarted. The default value is 2000. | no | pageSize |
| Redelivery Delay | The delay in milliseconds before a rolled back or recovered message is redelivered. Set to 0 to disable redelivery. The default value is 0. A value of -1 indicates the default value should be used. | no | redeliveryDelay |
| DLQ | The JMX ObjectName of the dead letter queue (DLQ) for this queue (e.g. "jboss.messaging.destination:service=Queue,name=PrivateDLQ") - overrides the default DLQ on the server peer. | no | DLQ |
| Expiry Queue | The JMX ObjectName of the expiry queue for this queue (e.g. "jboss.messaging.destination:service=Queue,name=PrivateExpiryQueue") - overrides the default expiry queue on the server peer. | no | expiryQueue |
| Server Peer | The JMX ObjectName of the server peer this queue was deployed on (e.g. "jboss.messaging:service=ServerPeer"). Updates to this property will not go into effect until the queue has been restarted. | no | serverPeer |
| Security Configurations | This element specifies a XML fragment which describes the access control list to be used by the SecurityManager to authorize client operations against the destination. The content model is the same as for the SecurityManager SecurityConf attribute. | yes | securityConfig |
Note
You must use the internal name to reference Configuration Properties in Dynamic Group Definition expressions.
