Instance Method Details

#graceful_disconnect ⇒ Object

This method contacts the server to send remaining data and let the server know that the agent is shutting down - this allows us to do things like accurately set the end of the lifetime of the process

If this process comes from a parent process, it will not disconnect, so that the parent process can continue to send data
