Chapter 7. Monitoring
Infinispan Query provides access to statistics and operations related to indexing. The statistics provide information about classes being indexed and entities stored in the index. Lucene query and object loading times can also be determined by specifying the
generate_statistics property in the configuration.
7.1. About Java Management Extensions (JMX)
Java Management Extension (JMX) is a Java based technology that provides tools to manage and monitor applications, devices, system objects, and service oriented networks. Each of these objects is managed, and monitored by
MBeans.
JMX is the de facto standard for middleware management and administration. As a result, JMX is used in Red Hat JBoss Data Grid to expose management and statistical information.
7.1.1. Using JMX with Red Hat JBoss Data Grid
Management in Red Hat JBoss Data Grid instances aims to expose as much relevant statistical information as possible. This information allows administrators to view the state of each instance. While a single installation can comprise of tens or hundreds of such instances, it is essential to expose and present the statistical information for each of them in a clear and concise manner.
In JBoss Data Grid, JMX is used in conjunction with JBoss Operations Network (JON) to expose this information and present it in an orderly and relevant manner to the administrator.
7.1.2. About JMX
Access to statistics via JMX can be enabled by setting the
default.jmx_enabled. This property automatically registers the StatisticsInfoMBean.
JMX beans are remotely accessed using the JConsole to set the
com.sun.management.jmxremote system property to true.
