[jira] Commented: (CAMEL-2364) Add an ability to display Cache
statistics via JMX in camel-cache
Posted by "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.

Claus Ibsen commented on CAMEL-2364:
------------------------------------
See section _registering your own managed endponts_
http://camel.apache.org/camel-jmx.html
Or chapter 12 in the Camel book :)
for how its possible to expose JMX attributes/operations in a Camel endpoint.
I wonder though if ehCache has its own JMX stats, people can use instead?

Hi Hadrian,
I got this request from a nabble request where this need was expressed. Please see below
http://old.nabble.com/camel-cache%3A-Using-Objects-for-cache-ts27026756.html
I fixed the serializable object support issue in CAMEL-2343 and created a Jira entry to capture this request.
My understanding based on what I saw in this request was that statistics from within ehCache (objects stored, deleted, expired, added, updated etc) be made available by camel-cache in addition to the camel component, endpoint & producer/consumer based JMX stats that are typically gathered by Camel.
The challenge with this request is how to make it more generic and express endpoint specific stats that can be leveraged by different endpoints.Ideally, something that can be extended/imlemented by different types of endpoints and not just for camel-cache.
Hope this helps.
Cheers,
Ashwin...

Ashwin, could you please add some details, like what statistics and how a user would see it?
