Metrics Message Producer

The metrics message producer shown in Figure 3–3 receives information from the metrics generator at regular intervals and writes the information into messages, which it then sends to one of a number of metric topic destinations, depending on the type of metric information contained in the message.

Message Queue clients subscribed to these metric topic destinations can consume the messages and process the metric data contained in the messages. This allows developers to create custom monitoring tools to support messaging applications. For details of the metric quantities reported in each type of metrics message, see Chapter 20, Metrics Information Reference, in Sun Java System Message Queue 4.3 Administration Guide. For information about how to configure the production of metrics messages, see Chapter 4, Using the Metrics Monitoring API, in Sun Java System Message Queue 4.3 Developer’s Guide for Java Clients and Using the Message-Based Monitoring API in Sun Java System Message Queue 4.3 Administration Guide.
