I think the "system" is somewhat more crude, but I recall reading that the A320 (and probably other types of that generation or later) does, for example, log the "G" of each landing - and if the log exceeds a certain value, a thorough check of the gear must be performed.
EDIT : The advantage in modern systems of having so many parameters monitored means that such functions can be performed without needing to add extra devices for measurement.
