    Abstract: In a delay time measuring apparatus a sequence number, data length, and receiving time of a data packet transmitted from a source unit to a destination unit are stored in a storage section. In addition, an ACK number and receiving time of an ACK packet returned from the destination unit to the source unit are stored in the storage section. After that, a calculation section obtains an ACK packet an ACK number of which is equal to a value obtained by adding data length of a second data packet of two successive data packets transmitted without waiting for the ACK packet to a sequence number of the second data packet of the two successive data packets from the storage section. Then the calculation section calculates round trip time from receiving time of the second data packet of the two successive data packets and receiving time of the ACK packet obtained.

    Abstract: A computer-readable non-transitory recording medium storing therein an information managing program causing a computer to execute extracting from among events that have occurred at objects under management and having dependence relations, combinations of a first event that has occurred at a source-of-dependence object and a second event that has occurred at a dependent object dependent on the source-of-dependence object; judging for each extracted combination, whether a dependence relation exists between the first event and the second event, by using the difference between the time of occurrence of the first event and that of the second event; determining from among the events and based on a judgment result obtained at the judging, an event that has occurred at an object that is a source-of-dependence object but not a dependent object, to be an event to be stored; and storing to a database, information related to the event to be stored.
