how to use it ?


Simple - don't.

No one wants to know if a connection is alive. What they want to know is whether the business logic is still functioning. And the only way to do that is to implement something that actually tests the functionality. The more fully it tests it the better. But at a minimum you can assure that the server is at least still responding to a message enough to return a response.

A simple implementation is to send a do nothing request from the client at a configured interval if no other request has been sent in that period.

And do NOT rely on such functionality to get around error checking legitimate requests. A server can go down right in the middle of a legitimate request.
