红帽全球峰会第 6 章 Using the management API
AMQ Broker has an extensive management API, which you can use to modify a broker’s configuration, create new resources (for example, addresses and queues), inspect these resources (for example, how many messages are currently held in a queue), and interact with them (for example, to remove messages from a queue).
In addition, clients can use the management API to manage the broker and subscribe to management notifications.
There are two ways to use the management API to manage the broker:
- Using JMX — JMX is the standard way to manage Java applications
- Using the JMS API — management operations are sent to the broker using JMS messages and the Red Hat build of Apache Qpid JMS client
Although there are two different ways to manage the broker, each API supports the same functionality. If it is possible to manage a resource using JMX it is also possible to achieve the same result by using JMS messages and the Red Hat build of Apache Qpid JMS client.
This choice depends on your particular requirements, application settings, and environment. Regardless of the way you invoke management operations, the management API is the same.
For each managed resource, there exists a Java interface describing what can be invoked for this type of resource. The broker exposes its managed resources in the org.apache.activemq.artemis.api.core.management package. The way to invoke management operations depends on whether JMX messages or JMS messages and the Red Hat build of Apache Qpid JMS client are used.
Some management operations require a filter parameter to choose which messages are affected by the operation. Passing null or an empty string means that the management operation will be performed on all messages.
