Measures reported by JbMQTopicTest

In the messaging world, messages are not sent directly to other applications. Instead, messages are sent to destinations, known as queues or topics. The JbMQTopicTest monitors the topics on the JBoss server.

Measurement Description Measurement Unit Interpretation
Max_topic_depth The max value of the number of messages in the topic since the start of the queue Number  
Msg_process_rate The rate at which messages are being processed by the topic in the last measurement period Msgs/Sec  
Durable_msg_count The number of durable messages currently in the topic Number  
Non_durable_msg_count The number of non-durable messages currently in the topic Number  
Total_sub_count The total number of subscribers to a topic Number  
Durable_sub_count The number of durable subscribers to the topic. Messages meant for a durable subscriber are stored in the persistent cache even when the subscriber is inactive. These messages are delivered to durable subscribers when they connect to the server. Number If the total number of durable subscribers is high, then we can expect the total durable messages to be stored on the server also to be relatively on the higher side.
Non_durable_sub_count The number of subscribers to the topic who are currently non-durable Number
