Database metrics can be collected, maintained, and used to help predict when processes go awry so problems can be resolved before they become severe. Understanding when an application or process misbehaves is not always easy. We are often left waiting until a server, application, or service breaks or enters an undesirable state before we know something is wrong. At that point, we are forced to rush and resolve a production problem quickly, before its impact becomes severe.

Also, it records only the page de-allocations in the transaction log, not the row-wise as in DELETE statement.
