How to verify entity caching from WildFly Admin Console?

[valsaraj007]

Is there any way to check entity caching in WildFly? I saw runtime tab but no change in the cache count.

I enabled it in persistence.xml:

<property name="hibernate.cache.use_second_level_cache" value="true"/>

...

<shared-cache-mode>ENABLE_SELECTIVE</shared-cache-mode>

Then annotated an entity as @Cacheable. Deployed and accessed via application. This is the entity which only used to read data from application.

Hi,

I'm not pretty sure about the Admin console, but you can gather 2LC statistics from the CLI by digging into the /deployments/deployment=yourapp and then into the jpa subsystem which contains the caches used by the application. You can also use a JMX Browser and point to your server domain, which exposes even more statistics about the cache.

It was due to mistake in 2LC configuration in my application. Now JPA section in Runtime showing results:

Put Count	71
Hit Count	417
Miss Count	9

What this miss count means? Can we get more details of this?

[f_marchioni]

The miss count simply means the number of times that an Entity/Query has been acquired from the database, an not from the cache.

I think the CLI provides more details about the Cache regions, through the /deployments subsystem.
