| Zusammenfassung: | The intermittent sampling of storage access frequency is performed by determining a duration of a collection window and a duration of an observation window within the collection window. A position of the observation window within the collection window is randomly selected, and frequencies of accesses of one or more storage objects during the observation window are observed. When a new access of a given storage object occurs, a delta time for the given storage object is calculated as the time of the observed access minus the timestamp of the most recent observed prior access of the given storage object. Optionally, the delta time of two sequential accesses of a given storage object in two different observation windows may be calculated as if the two different observation windows are immediately adjacent to each other. |
