[hibernate-dev] Hibernate Metrics support

[Mihalcea Vlad]

Hi Steve,
I was thinking of having a Metrics gathering API for all sorts of database-related operations:
- connection acquiring/lease time- connection wait time- transaction durations- SQL query logger 
- slow queries threshold- number of queries per transaction threshold
Something similar to https://github.com/vladmihalcea/flexy-pool 

This will ease profiling a Hibernate application and we could have the hibernate-core define the integration hooks anda hibernate-metrics module to inject the metrics gathering components. This module could use Dropwizard Metrics, sinceit supports various Reservoir types and many reporting flavors (log, JMX, Graphite).
Hibernate users will get an insight of what's going on in their application, so they can better understand what Hibernate doeson their behalf.
What do you think of this?
