I'm working on large enterprise application that has many hibernate calls to database. I want to track down which session opened and which is closed.
So is there anything in hibernate we can get unique ID of that session or something else. Basic idea is to track down the session execution time. I checked many profiler but its not giving the proper output.

The Session interface is the main tool used to communicate with Hibernate. It provides an API enabling us to create, read, update, and delete persistent objects. The session has a simple lifecycle. We open it, perform some operations, and then close it.
A transaction is associated with a Session and is usually instantiated by a call to Session. beginTransaction(). A single session might span multiple transactions since the notion of a session (a conversation between the application and the datastore) is of coarser granularity than the notion of a transaction.
When you don't close your Hibernate sessions and therefore do not release JDBC connections, you have what is typically called Connection leak. So, after a number of requests (depending on the size of your connection pool) the server will not be able to acquire a connection to respond your request.
23) Does Hibernate Session interface is thread-safe in Java? No, Session object is not thread-safe in Hibernate and intended to be used with-in single thread in the application.
You can use session.toString() to display the session id and it's status, open or close.
