I have some data being recorded for analysis on a remote computer which saves the data to a server. In past this recording failed without any knowledge to the operator and was left unattended. If their a way to get an alert when the server stops receiving any data for some fixed time as a check. I am using PostgreSQL on a linux machine and have very less knowledge of cRON jobs etc (i hear that it is what will be required to setup).
I am required to come-up with a script to check the data recording which will act as the trigger for the alert.
