  However, the technique of notifying the administrator when the used capacity exceeds the threshold value places a burden on the administrator. In addition, the other technologies are merely reactive measures, and do not affect the manner in which the user uses the disk, and do not contribute to the reduction of the disk usage capacity. The present invention works on the disk usage morals of the user to manage the disk capacity and reduce the used capacity.

  The storage device capacity threshold management program of the present invention refers to a threshold table that stores a threshold for each terminal in the server, and when the used capacity of the storage device of the terminal exceeds the threshold, A function for issuing a warning, a table for storing the time at which the warning is issued, a function for obtaining the time at which the warning is issued, and a capacity used for the storage device in association with the time for each terminal. Referring to the stored capacity table, the terminal issues a warning from the function of obtaining the time when the used capacity of the storage device is reduced, the time when the warning is issued, and the time when the used capacity is deleted. A function for calculating the corresponding time required from the time of deletion to deletion and a table that stores the corresponding time and the value used for changing the threshold in association with each other, and stores the value based on the calculated corresponding time. Get the value And a function for setting a new threshold based on the threshold table, and based on the time until the user performs the deletion measure based on the warning, the terminal uses the capacity of the storage device used by the terminal. This is for managing a threshold value for issuing a notification.

  In addition, the storage device capacity threshold management program of the present invention refers to the capacity table, and acquires the used capacity when the warning is issued and the used capacity when the terminal reduces the used capacity of the storage device. And referring to a table that stores the function for calculating the deletion capacity of the used capacity and the value for use in changing the deletion capacity and the threshold value, and acquires the value based on the calculated deletion capacity In addition, by realizing a function of setting a new threshold value based on the value in the threshold value table, it is possible to manage the threshold value based on the user's deletion capacity instead of or in addition to the time until the deletion. It is.

  As described above, according to the present invention, the user who uses the terminal issues a warning based on the time from when the warning about the used capacity of the disk is performed until the measure such as the deletion is performed or the deleted capacity. It is possible to change the threshold value for this, and it is possible to manage the disk capacity and reduce the used capacity by working on the disk usage morals of the user by the fluctuation of the threshold value.

  Embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 shows an example of the configuration of the present invention. The embodiment shown in FIG. 1 includes a server 1 to which a program according to the present invention is applied, a user terminal 2 used by a user, and a network 3 connecting them. Both the server 1 and the user terminal 2 are configured by a computer. Moreover, although only one user terminal 2 is shown in the figure, a plurality of connections are usually made.

  The server 1 includes a monitoring unit 11, a notification unit 12, a capacity recording unit 13, a deletion capacity calculation unit 14, a threshold recalculation unit 15, a threshold resetting unit 16, a threshold table 17, a capacity table 18, and a cooperation index table 19. Yes.

  The monitoring unit 11 monitors the used capacity of each user in a storage device such as a disk shared by a plurality of user terminals 2. The disk device is not shown.

  The notification unit 12 transmits a warning to the terminal of the user when the used capacity for each user terminal 2 obtained by the monitoring unit 11 exceeds a threshold set in a threshold table 17 described later. It is.

  The capacity recording unit 13 records the used capacity of the storage device for each user terminal 2 obtained by the monitoring unit 11 in a capacity table 18 described later in time series. Further, when a warning is issued by the notification means 12, it is recorded together as a warning flag.

  The deleted capacity time calculation means 14 refers to the capacity table 18 to obtain the used capacity or time when a warning is issued and when the user responds to the warning and cancels the warning. The deletion capacity is calculated by reducing the use capacity by deleting the corresponding time or data required until the user responds.

  The threshold recalculation unit 15 refers to the cooperation index table 19 and acquires a cooperation index as a point based on the corresponding time or the deleted capacity, and calculates a new threshold.

  The threshold resetting unit 16 sets a new threshold obtained by the threshold recalculating unit 15 in the threshold table 17.

  The threshold value table 17 is a table storing a threshold value 172 for each user ID 171, and an example is shown in FIG. The threshold table 17 is referred to by the notification unit 12 and used for notifying a warning, and a new threshold is set by the threshold resetting unit 16. In the example of FIG. 2A, 700 MB is set as the threshold value 172 for the user terminal 2 having the user ID 171 of A.

  The capacity table 18 is a table that stores the used capacity of the storage device for each user terminal 2 in time series in association with the user ID 181 of the user terminal 2, and an example is shown in FIG. In the example of FIG. 3, the used capacity of the storage device of the user terminal 2 whose user ID 182 of “10th 0:00” is A is “450 MB”. Further, when the used capacity of the storage device exceeds the threshold value, the notification unit 12 issues a warning to the user terminal 2, and this warning is also set as a warning flag 183 when such a warning is generated. Similarly, it is stored in time series. For example, for the user terminal 2 whose user ID 181 is “A”, it means that a warning is issued at “10th 10th” and “10th 12:00”.

  The degree of cooperation with respect to the reduction in the amount of use of the storage device of the user is measured by the deletion capacity at the time of receiving the warning, or the response time until the deletion is performed, and the cooperation index table 19 has threshold values for those numerical values. It is a table which stores the increase amount in association with each other. In this embodiment, it is set as a point for the deletion rate or the corresponding time. For example, if the point is “5”, the reset threshold value is increased by 5% before the update. Here, it is set as a point representing the rate of increase, but it may be set at a fixed value such as “10 MB”.

  Next, an example of processing contents of the storage device capacity threshold management program according to the present invention will be described with reference to the processing flowcharts shown in FIGS.

  FIG. 5 shows an example in which the deletion capacity is adopted as the cooperation index. That is, in the cooperation index table shown in FIG. 4, the table (A) is used. The processing shown in this flow is assumed to be performed periodically like daily processing. For example, it may be executed once every 24 hours, but is not limited thereto. It is also conceivable that the user terminal 2 recognizes that the deletion process has been performed instead of the daily process. In that case, a warning is issued to a certain user terminal 2, data is subsequently deleted, and the processing from step S <b> 54 to step S <b> 57 is performed by canceling the state in which the warning is issued. And it is sufficient.

  When the process is started as the daily process, the process proceeds to step S51. Here, it is assumed that processing is performed at 0:00 every day. In step S51, it is determined whether or not processing has been performed for all users. If there are users who have not been processed, the process proceeds to step S52. If the processing for all users is completed, the daily processing is ended. Here, the following description will be given on the assumption that processing is performed for a user whose user ID 181 is “A”.

  In step S52, the capacity table 18 is referenced to determine whether or not the warning flag 183 has been generated. If there is a warning flag 183, the process proceeds to step S53, and if not, the process proceeds to step S51. Here, when the warning flag 183 is searched for the user terminal 2 having the user ID 181 of “A”, the warning flag 183 is generated at “10 o'clock 10 o'clock”, and the process proceeds to step S53.

  In step S53, it is determined whether or not the warning flag 183 once generated is cleared. If resolved, the process proceeds to step S54, and if not resolved, the process proceeds to step S51. This flow is because the present invention evaluates the user's response to the issued warning and changes the threshold value. Therefore, the user has not yet taken any action. This is because if the warning flag 183 is not cleared, it is not subject to evaluation. Here, when the warning flag 183 is searched for the user terminal 2 having the user ID 181 of “A”, the warning flag once generated is cleared at “14:00 on the 10th”, and the process proceeds to step S54.

  In step S54, the deleted capacity time calculation means 14 refers to the capacity table 18, acquires the used capacity 182 of the storage device when the warning flag 183 is generated and when it is canceled, and calculates the difference. Here, the value “1000 MB” is acquired as the used capacity 182 when the warning flag 183 is generated, and the value “600 MB” is acquired as the used capacity when the warning flag 183 is canceled, and the difference is “400 MB”.

  In step S55, the threshold recalculation unit 15 refers to the cooperation index table 19 based on the deleted capacity calculated in step S54, and acquires points of the cooperation index. Here, the table (A) shown in FIG. 4 is referred to. In the table, points are associated with deletion ratios. Therefore, when “400 MB” is divided by “1000 MB” to obtain the deletion ratio of the user of “A”, “0.4”, that is, “40%” is obtained, and the associated point is “3”. Therefore, “3” is acquired as the cooperation index.

  In step S56, the threshold recalculation means 15 calculates a threshold from the cooperation index obtained in step S55. The threshold value 172 “700 MB” of the user ID 171 “A” is acquired from the threshold value table 17 before update shown in FIG. Then, based on the cooperation index “3” percent acquired in step S55, “700 MB” is multiplied by “1.03” to obtain a new threshold value of “721 MB”.

  In step S57, the threshold resetting unit 16 sets the new threshold obtained in step S56 in the threshold table 17, and the process proceeds to step S51. Here, the new threshold value “721 MB” obtained in step S56 is set to the threshold value 172 corresponding to “A” in the user ID 171 in the updated threshold value table 17 and the process proceeds to step S51.

  Next, the processing flow shown in FIG. 6 will be described. The process shown here is an example in the case where the corresponding time is adopted as the cooperation index, and the cooperation index table 19 refers to the (B) corresponding time table shown in FIG. The processes in steps S61 to S63 and step S67 are the same as the processes in steps S51 to S53 and step S57 in FIG. Here, processing for a user whose user ID 181 is “B” will be described as an example.

  In step S64, the deleted capacity time calculation means 14 refers to the capacity table 18, obtains the time when the warning flag 183 is generated and when it is cleared, and calculates the difference. Here, a value of “10 days 2 o'clock” is acquired as the time when the warning flag 183 is generated, and “10 days 18:00” is acquired as the time of cancellation, and the corresponding time is “16 hours”.

  In step S65, the threshold recalculation unit 15 refers to the cooperation index table 19 based on the corresponding time calculated in step S64, and acquires points of the cooperation index. Here, referring to the table of (B) shown in FIG. 4 based on the value of “16 hours (16H)” obtained in step S64, the associated point is “3”. Therefore, “3” is acquired as the cooperation index.

  In step S66, the threshold recalculation means 15 calculates a threshold from the cooperation index obtained in step S65. The threshold value 172 “500 MB” of the user ID 171 “B” is acquired from the threshold value table 17 before update shown in FIG. Then, based on the cooperation index “3” percent acquired in step S65, “500 MB” is multiplied by “1.03” to obtain a new threshold value of “515 MB”.

  Next, the processing flow shown in FIG. 7 will be described. The process shown here is an example in the case where both the deletion capacity and the corresponding time are adopted as the cooperation index. As the cooperation index table 19, the table of (A) deletion capacity and (B) corresponding time shown in FIG. refer. The processing in steps S71 through S73 and step S77 is the same as the processing in steps S51 through S53 and step S57 in FIG.

  In step S74, the processes of step S54 and step S64 are performed together.

  In step S75, the processes of step S55 and step S65 are performed together. Here, as an example, it is assumed that (A) “2” is acquired as a point from the deleted capacity table, and (4) “4” is acquired from the corresponding time table.

  Several variations are conceivable as the processing performed in step S76. As an example, the two points obtained in step S75 can be added together to obtain “6” as a point, and a new threshold can be obtained by multiplying the threshold before update by “1.06”. As another example, a value obtained by multiplying a threshold before update by “1.02” and further multiplying by “1.04” can be used as a new threshold.

A storage device such as a RAM (Random Access Memory) and a hard disk device (HDD), a graphic processing unit, an input interface, a communication interface, and the like are connected to the CPU via a bus.
