This metric is not important in its own right, and viewing the data points on the Analysis page will not provide useful information. The metric is a necessary step in order to achieve the key purpose of this metric, which is to create an alert that will be raised when something is added to the schema, or the existing schema is modified.
Note: If you delete a schema object such as a table, constraint or index, an alert is not raised.
