Monitoring
In short and in plain language
Monitoring makes it visible how the link between programs runs.
You can see if the last sync is done. You also see how long it took. And you see how many records were left behind.
Without this view, you only spot a fault when customers or your accounts team tell you.
Definition
Monitoring makes the interface run visible: did the last sync finish, how long did it take, how many records were left behind? Without that view, an outage surfaces only when customers or the accounting team report it.
