You might get an error message saying that you cannot create a new point because your data stream limitations are exceeded, even though the Licensing tool says you still have points left. This is a common point of confusion that occurs because what you are actually licensed for is the number of data streams, not the number of points. Data streams are points and modules.
For example, suppose you think that you are licensed for 5000 points. If you look at your point count (pibasess.MaxPointCount) and see that Amount Used is 4000, you might assume that you have 1000 points left. However, your license counts data streams, rather than points. That means you also need to know how many modules you are using (pibasess.MaxModuleCount).
It is best to monitor your point and module count together (pibasess.MaxAggregatePointModuleCount). Total shows you how many data streams (points and modules together) you are licensed for, Amount Used shows you how many data streams you are using, and Amount Left shows you how many data streams you have left.
