Abstract
A method and apparatus for monitoring update activity, particularly in the form of write requests, to a data storage facility, over at least one cycle to identify any write operation or update that occurs to that data storage facility on a track-by-track basis. At the end of each cycle a list of changed tracks is stored in a data set. After information has been accumulated by a collector application, a reporter application manipulates the data to obtain information concerning the track changes and to estimate communication path requirements.
