==== Hibernate Metrics
Auto-configuration enables the instrumentation of all available Hibernate
`EntityManagerFactory` objects that have statistics enabled with a metric named
`hibernate`.
Metrics are also tagged by the name of the `EntityManagerFactory` that is derived from

To enable statistics on Hibernate `EntityManagerFactory` instances, JPA property `hibernate.generate_statistics` must be set to `true`. For example, on the default
`EntityManagerFactory`, you need to set the following property:
.application.properties
