* Called whenever the program ETAMonitor attempts to make a connection to this instance of ETA.

* this is to provide a gateway to the job that is running in case the user wants to send data to
* job and it tells ETA that the job started on which machine and when it finishes. It also gets
* the exit code to check if the job finished properly.
