Abstract: The procedure includes referring to data including information on an operation task performed with respect to each of a plurality of devices, the data being associated with each of the plurality of devices, extracting a first device in which a number of operation tasks performed during a specific period satisfies a criterion, displaying the information on the operation task performed during the specific period with respect to the first device, in association with the first device, upon receiving designation of a time or a first time zone, referring to the data, extracting a second device in which the number of operation tasks performed in a second time zone depending on the time or the first time zone satisfies a criterion, and displaying the information on the operation task performed in the second time zone with respect to the second device, in association with the second device.

Abstract: An analysis apparatus includes one or more memories configured to store a plurality of pieces of reception information and a plurality of pieces of maintenance information in association with each other, each of the plurality of pieces of reception information including inquiry information on an information processing system and answer information created to the inquiry information, each of the plurality of pieces of maintenance information representing contents of a maintenance operation performed on the information processing system, and one or more processors configured to perform identifying a number N which indicates how many pieces of reception information are associated with first maintenance information which is stored in association with first reception information in the one or more memories, and perform calculation of an evaluation value of the first reception information on the basis of the identified number N.

Abstract: An apparatus includes a memory to store objects of a plurality of classes, and a storage device to store plural pieces of dump data acquired at different times from the memory. The apparatus generates object-count information indicating a number of objects belonging to each of a plurality of classes, based on the plural pieces of dump data acquired at different times from a memory storing objects of the plurality of classes. The apparatus determines, for each class, at least a portion of dump data that includes a locally minimum number of objects in time variation of the number of objects of the each class, as first dump data that is candidate for storage, based on the generated object-count information. When reducing a total amount of dump data, the apparatus excludes the first dump data determined for each class from second dump data that is to be deleted.
