How are the E4JMS Queues and Topics information derived?

We use both TopicInfo and QueueInfo classes included in the tibco libraries:

https://docs.tibco.com/pub/enterprise_message_service/8.1.0/doc/html/tib_ems_api_reference/api/javadoc/com/tibco/tibjms/admin/TopicInfo.html

https://docs.tibco.com/pub/enterprise_message_service/8.1.0/doc/html/tib_ems_api_reference/api/javadoc/com/tibco/tibjms/admin/QueueInfo.html

Both call functions defined in DestinationInfo:

https://docs.tibco.com/pub/enterprise_message_service/8.1.0/doc/html/tib_ems_api_reference/api/javadoc/com/tibco/tibjms/admin/DestinationInfo.html

This functions are getInboundStatistics and getOutboundStatistics. These will return a value of type StatData:

https://docs.tibco.com/pub/enterprise_message_service/8.1.0/doc/html/tib_ems_api_reference/api/javadoc/com/tibco/tibjms/admin/StatData.html


We're interested in getMessageRate and getByteRate:

bytesIncoming - getInboundStatistics().getByteRate()
msgsIncoming - getInboundStatistics().getMessageRate()
bytesOutgoing - getOutboundStatistics().getByteRate()
msgsOutgoing - getOutboundStatistics().getMessageRate()
