21.3. JMX Statistic Levels

download PDF
JMX statistics can be enabled at two levels:
  • At the cache level, where management information is generated by individual cache instances.
  • At the CacheManager level, where the CacheManager is the entity that governs all cache instances created from it. As a result, the management information is generated for all these cache instances instead of individual caches.


In Red Hat JBoss Data Grid, statistics are enabled by default in Remote Client-Server mode and disabled by default for Library mode. While statistics are useful in assessing the status of JBoss Data Grid, they adversely affect performance and must be disabled if they are not required.
