5.4. Runtime Management Information
JBoss Cache includes JMX MBeans to expose cache functionality and provide statistics that can be used to analyze cache operations. JBoss Cache can also broadcast cache events as MBean notifications for handling via JMX monitoring tools.
5.4.1. JBoss Cache MBeans
Copia collegamentoCollegamento copiato negli appunti!
JBoss Cache provides an MBean that can be registered with your environments JMX server to allow access to the cache instance via JMX. This MBean is the
See the
org.jboss.cache.jmx.CacheJmxWrapper. It is a StandardMBean, so its MBean interface is org.jboss.cache.jmx.CacheJmxWrapperMBean. This MBean can be used to:
- Get a reference to the underlying
Cache. - Invoke create/start/stop/destroy lifecycle operations on the underlying
Cache. - Inspect various details about the cache's current state (number of nodes, lock information, etc.)
- See numerous details about the cache's configuration, and change those configuration items that can be changed when the cache has already been started.
CacheJmxWrapperMBean Javadoc for more details.
If a
CacheJmxWrapper is registered, JBoss Cache also provides MBeans for several other internal components and subsystems. These MBeans are used to capture and expose statistics related to the subsystems they represent. They are hierarchically associated with the CacheJmxWrapper MBean and have service names that reflect this relationship. For example, a replication interceptor MBean for the jboss.cache:service=TomcatClusteringCache instance will be accessible through the service named jboss.cache:service=TomcatClusteringCache,cache-interceptor=ReplicationInterceptor.
