Cache Statistics
Metrics for various cache resources related to loading business objects. Cache objects expire upon modification or in case they have aged out. A high Cache miss rate should be investigated as well as Cache loads failure.

EntityProxyCache
Cache metrics pertaining the retrieval of Entity objects.
Persistence Manager Cache
Cache metrics pertaining the retrieval of business objects from the persistence store.
DataGraphContainerCache
Cache metrics related to loading single business objects.
Report Cache
Cache metrics corresponding to loading of Report Store.
Hibernate Statistics
Metrics for all database change events triggered by queries, statements, connections, sessions, transactions, flushes etc.
Hibernate is the persistence service of the application and responsible for loading, saving and deleting data from the databases. Any change to the database requires a query or a statement, a connection, a session, a transaction, a flush, and there are metrics for all events.
Important Hibernate metrics are the amount of queries executed and especially queries which take a lot of time.
