Monitoring EhCache with JMX and Spring

EhCache provides an easy way to manage your caches with JMX. The ManagementService class is the API entry point. You can easily integrate it in your Spring configuration files.

Here's how you can do it :

  <ehcache:config configLocation="classpath:config/ehcache.xml" failQuietly="true" />
 
  <ehcache:annotations>
    <ehcache:caching id="yourCacheModel" cacheName="yourCache"/>
  </ehcache:annotations>
 
  <bean id="mbeanServer" class="org.springframework.jmx.support.MBeanServerFactoryBean">
    <property name="locateExistingServerIfPossible" value="true" />
  </bean>

  <bean class="net.sf.ehcache.management.ManagementService" init-method="init">
    <constructor-arg ref="cacheManager" />
    <constructor-arg ref="mbeanServer" />
    <constructor-arg value="true" />
    <constructor-arg value="true" />
    <constructor-arg value="true" />
    <constructor-arg value="true" />
  </bean>

After doing this, you will have access to your caches configuration and operations such as cache flushing. You will also have access to useful statistics like cache hits, cache misses, object count and some more. These statistics will give you critical information on how to configure your caches for an optimal use.
