21.8. MBeans

An MBean represents a manageable resource such as a service, component, device or an application.
Red Hat JBoss Data Grid provides MBeans that monitor and manage multiple aspects. For example, MBeans that provide statistics on the transport layer are provided. If a JBoss Data Grid server is configured with JMX statistics, an MBean that provides information such as the hostname, port, bytes read, bytes written and the number of worker threads exists at the following location: 
jboss.infinispan:type=Server,name=<Memcached|Hotrod>,component=Transport

MBeans are available under two JMX domains:
  • jboss.as - these MBeans are created by the server subsystem.
  • jboss.infinispan - these MBeans are symmetric to those created by embedded mode.
Only the MBeans under jboss.infinispan should be used for Red Hat JBoss Data Grid, as the ones under jboss.as are for Red Hat JBoss Enterprise Application Platform.

Note

A full list of available MBeans, their supported operations and attributes, is available in the Appendix

21.8.1. Understanding MBeans
Copia collegamento

When JMX reporting is enabled at either the Cache Manager or Cache level, use a standard JMX GUI such as JConsole or VisualVM to connect to a Java Virtual Machine running Red Hat JBoss Data Grid. When connected, the following MBeans are available:
  • If Cache Manager-level JMX statistics are enabled, an MBean named jboss.infinispan:type=CacheManager,name="DefaultCacheManager" exists, with properties specified by the Cache Manager MBean.
  • If the cache-level JMX statistics are enabled, multiple MBeans display depending on the configuration in use. For example, if a write behind cache store is configured, an MBean that exposes properties that belong to the cache store component is displayed. All cache-level MBeans use the same format: 
    jboss.infinispan:type=Cache,name="<name-of-cache>(<cache-mode>)",manager="<name-of-cache-manager>",component=<component-name>

    In this format:
    • Specify the default name for the cache using the cache-container element's default-cache attribute.
    • The cache-mode is replaced by the cache mode of the cache. The lower case version of the possible enumeration values represents the cache mode.
    • The component-name is replaced by one of the JMX component names from the JMX reference documentation.
As an example, the cache store JMX component MBean for a default cache configured for synchronous distribution would be named as follows: 
jboss.infinispan:type=Cache,name="default(dist_sync)", manager="default",component=CacheStore

Each cache and cache manager name is within quotation marks to prevent the use of unsupported characters in these user-defined names.

21.8.2. Registering MBeans in Non-Default MBean Servers

The default location where all the MBeans used are registered is the standard JVM MBeanServer platform. Users can set up an alternative MBeanServer instance as well. Implement the MBeanServerLookup interface to ensure that the getMBeanServer() method returns the desired (non default) MBeanServer.
To set up a non default location to register your MBeans, create the implementation and then configure Red Hat JBoss Data Grid with the fully qualified name of the class. An example is as follows:
To Add the Fully Qualified Domain Name Declaratively

Add the following snippet: 

<globalJmxStatistics enabled="true" mBeanServerLookup="com.acme.MyMBeanServerLookup"/>
Copy to Clipboard Toggle word wrap
To Add the Fully Qualified Domain Name Programmatically

Add the following code: 

GlobalConfiguration globalConfiguration = new
GlobalConfigurationBuilder().globalJmxStatistics().enable().
mBeanServerLookup("com.acme.MyMBeanServerLookup").build();
