One of applications captures data from various appliances, such a call data records from telephone switches. If the connection with the telephone switch is lost, CRDs are lost as is the revenue from rebilling those telephone calls, and this can make a lot of customer anxiety, or worse. The better telephone switches, like Avaya, have a special protocol to ensure CDRs don't get lost, but I've not managed to support it yet. So being able to alert a lost TCP connection can be very useful, even though there is no control over the remote appliance.
