I’ve used logging in both my professional and hobby projects. One system used satellite communications to obtain data from remote pipeline locations. Two notable locations were the side of a mountain in Nevada which was totally inaccessible in the winter and a swamp in the middle of Louisiana. These remote units, and their counterparts at the client’s data centers, provided log data about the operation of the communications to our 24/7 operations center. It wasn’t unusual for our operators to contact a client about a remote site going down before the client’s operators noticed the problem.
