["John Ellis (JIRA)" <ji...@apache.org>]

John Ellis commented on CAMEL-2364:
-----------------------------------

EhCache does have its own statistics. Here's a snippet on how to expose them via JMX in a Spring application context:
    <bean id="ehCacheManagementService" class="net.sf.ehcache.management.ManagementService" init-method="init" lazy-init="false">
        <constructor-arg>
            <bean class="net.sf.ehcache.CacheManager" factory-method="getInstance"/>
        </constructor-arg>
        <constructor-arg>
            <bean class="org.springframework.jmx.support.JmxUtils" factory-method="locateMBeanServer"/>
        </constructor-arg>
        <constructor-arg value="true"/>
        <constructor-arg value="true"/>
        <constructor-arg value="true"/>
        <constructor-arg value="true"/>
    </bean>

Of course you can do the same thing in straight Java:
  ManagementService.registerMBeans(CacheManager.getInstance(), mbeanServer, true, true, true, true);

You can get cache hits, misses, in-memory hits, disk hits, size stats this way. You can also change CacheConfiguration parameters on the fly.
