Abstract: An apparatus is connected to a first storage and a second storage which is accessed at an access speed lower than an access speed of the first storage. The apparatus accesses each of blocks stored in the second storage, and counts, for each of the blocks, the number of accesses made for the each block. The apparatus determines, based on the number of accesses that has been counted for each of the blocks, a transfer target block that is a target which is to be transferred from the second storage to the first storage, and determines a transfer time at which transfer of the transfer target block is to be performed. The apparatus transfers the determined transfer target block to the first storage at the determined transfer time.

A second memory unit stores request-destination event information pieces each including time information indicating an occurrence time of an event associated with a process executed by a second server in response to a request from the first server. A determining unit determines, for each request-destination event information piece, a correction allowable range of the time information by comparing the time information of the request-destination event information pieces with that of the requester event information pieces.

Abstract: From unit storage areas each having a certain size in a first storage device, an extraction unit extracts, at certain time intervals, a monitored area formed by consecutive unit storage areas having been accessed at least a predetermined number of times that is greater than zero and being similar to each other in the number of times of access. When detecting movement between the positions of same-sized monitored areas among the extracted monitored areas over time, a prediction unit determines a predicted storage area predicted to be accessed in the storage area of the first storage device on the basis of the direction of the movement between the positions of the same-sized monitored areas, and performs a control operation so that the content of the predicted storage area is copied to a second storage device that provides faster access than the first storage device.

Abstract: A first memory stores requester event records describing events that occurred in relation to processes executed in a first server. A second memory stores requestee event records describing events that occurred in relation to processes executed in a second server in response to execution requests issued from the first server. An associating unit searches the first and second memories for requester event records and requestee event records whose transaction identifiers are identical and associates the found records together. A determining unit compares the associated event records with each other in terms of their time information. Based on this comparison, the determining unit determines a correction value for correcting time differences between requester event records in the first memory and requestee event records in the second memory.

A detection unit detects time windows whose total processing times are equal to or longer than the threshold.
