Here, in this embodiment, it is assumed that each piece of identification information is stored in the client identification information column 51D and the measurement service identification information column 52D in advance.
[0021]
[Display system operation]
Next, the operation of the display system of this embodiment will be described with reference to FIGS. First, the measurement processing operation on the client machine 4 side will be described with reference to the flowchart of FIG.
[0022]
Here, a measurement process of the congestion status with the Web server 1 will be described. First, the operator issues a service provision instruction (in this case, a request for downloading a desired Web content) from the instruction unit 4e of the client machine 4 to the Web server 1 (step ST1). Here, at the same time that the instruction is sent to the Web server 1, the CPU of the client machine 4 starts measuring the service providing time by the measurement function 41B (step ST2).
[0023]
Subsequently, the Web server 1 that has received the download request instruction transmits the Web content to the client machine 4. Then, the CPU of the client machine 4 stops the measurement at the same time when the service is provided, that is, receives the Web content (step ST3), calculates the service provision time by the measurement function 41B, and acquires the measurement value data. (Step ST4). At that time, measurement service identification information is also acquired. Since the service is provided from the Web server 1 this time, “Web” data is acquired as measurement service identification information. Note that the measurement service identification information may be acquired by recognizing the instruction destination at the time of the service provision instruction in step ST1 described above, or may be input by an operator.
[0024]
The CPU of the client machine 4 that acquired the measurement value data uses the measurement function 41B to search for a record in each measurement information management table in the table storage unit 4c that matches the acquired measurement service identification information ("Web" data). (Step ST5) If there is a matching record, the corresponding measurement information management table (here, the measurement information management table 4C shown in FIG. 2B) ₁ ). If there is no matching record, the measurement process is terminated. Subsequently, the CPU reads the measurement information management table 4C that has been read. ₁ In the measured value information column 42C, the acquired measured value data is recorded (the measured information management table 4C ₁ If it is recorded for the second time or later), the measurement information management table 4C ₁ Is stored in the table storage unit 4c (step ST6).
[0025]
Next, a process for measuring the congestion status with the file server 2 will be described. Even in this case, measurement processing is performed as in steps ST1 to ST6 in the flowchart of FIG. 4 in the same manner as in the case of the Web server 1 described above, and the measurement information management table 4C shown in FIG. ₂ Is stored in the table storage unit 4c. In this case, “Web server 1” is “file server 2”, “Web content” is “file”, “download request instruction” is “file transfer instruction”, and “Web data” is “file”. "Data" and "Measurement information management table 4C ₁ "Measurement information management table 4C ₂ "
[0026]
The processing for measuring the congestion status with the DB server 3 is performed as follows. First, as shown in FIG. 4, the operator issues a service provision instruction (in this case, a desired transaction processing instruction) to the DB server 3 from the instruction unit 4e of the client machine 4 (step ST1). Here, at the same time that the instruction is sent to the Web server 1, the CPU of the client machine 4 starts measuring the service providing time by the measurement function 41B (step ST2).
[0027]
Subsequently, the DB server 3 receiving the transaction processing instruction performs a requested process such as rewriting data in the database, for example, and transmits the result to the client machine 4. Then, the CPU of the client machine 4 stops providing the service, that is, receives the result (step ST3), calculates the service providing time by the measurement function 41B, and obtains the measured value data ( Step ST4). Thereafter, measurement processing is performed in the same manner as in the case of the Web server 1 described above, and the measurement information management table 4C shown in FIG. ₃ Is stored in the table storage unit 4c. In this case, “Web server 1” is “DB server 3”, “Web data” is “DB data”, and “Measurement information management table 4C”. ₁ "Measurement information management table 4C ₃ "
[0028]
Next, the CPU of the client machine 4 uses the transmission function 42B to update the measurement information updated from the table storage unit 4c when the image drawing time (redrawing time when redrawing the image) is reached (step ST7). Management table (in this case, measurement information management table 4C ₁ ~ 4C ₃ ) Is read and transmitted to the congestion state drawing machine 5 (step ST8). If the drawing time (redrawing time) has not yet been reached, the system waits until the drawing time (redrawing time) is reached. In such a case, when the service is received again before the drawing time (redrawing time), the measurement information management table is updated again after performing the above-described measurement processing. Here, the drawing time (redrawing time) refers to, for example, a time at a predetermined interval or a predetermined time, and can be arbitrarily set in advance by the operator. The drawing time (redrawing time) may be set for each measurement service identification information, for example, or set regardless of the measurement service identification information (that is, all the updates are made when that time comes). Sent measurement information management table). In the present embodiment, the latter is illustrated.
[0029]
Next, the drawing processing operation on the congestion state drawing machine 5 side will be described with reference to the flowchart of FIG. First, the measurement information management table 4C from the client machine 4 ₁ ~ 4C ₃ The CPU of the congestion state drawing machine 5 that has received (step ST11) receives the measurement information management table 4C. ₁ ~ 4C ₃ Are stored in the reception table storage unit 5e, and the basic image data and the changed image data are read from the image component storage unit 5c (step ST12).
[0030]
Subsequently, the CPU of the congestion state drawing machine 5 receives the received measurement information management table 4C. ₁ ~ 4C ₃ Each time, the importance determination table that matches both the client identification information and the measurement service identification information is read from the table storage unit 5d, and the measurement information management table 4C is read from the table. ₁ ~ 4C ₃ The importance level determination table having the range information of the measured value X corresponding to the measured value information in the measured value information column 42C is searched. Then, the corresponding color information is determined based on the color information column 54D of the retrieved importance determination table (step ST13). For example, when the case of the Web server 1 is illustrated, first, the measurement information management table 4C shown in FIG. ₁ Importance determination table that matches both client identification information and measurement service identification information (importance determination table 5D shown in FIGS. 3B to 3D) ₁ ~ 5D ₃ ) Is read from the table storage unit 5d, and the importance determination table 5D having range information of the measurement value X corresponding to the measurement value information “4s” in the measurement value information column 42C from the table storage unit 5d. ₂ Search for. And the importance determination table 5D ₂ The corresponding color information is determined to be “yellow” based on the color information column 54D.
[0031]
Subsequently, the CPU of the congestion state drawing machine 5 uses the drawing function 52B to expand the basic image data read in step ST12 into, for example, a memory (not shown) and to determine the determined color as the line data of the changed image data. The information is reflected and developed in the memory, and an image of the congestion situation is drawn (step ST14). For example, as shown in FIG. 6, the first to fourth basic images 51C, which are basic image data. ₁ ~ 51C ₄ And then the first to third lines 52C ₁ ~ 52C ₃ Draw with color information reflected in. Taking the case of the Web server 1 as an example, the first line 52C ₁ Draw with "yellow".
[0032]
Next, the CPU of the congestion state drawing machine 5 creates supplementary information using the supplementary information creation function 53B. First, the CPU reads the supplementary information image data from the image component storage unit 5c (the first and second supplementary information images 53C described above in the present embodiment shown in FIG. 6). ₁ , 53C ₂ ) Is read (step ST15), and supplementary information is input (step ST16). In such a case, the CPU of the congestion situation drawing machine 5 performs the first supplementary information image 53C. ₁ Since the average value of the service provision time for each server is input as supplementary information, the measurement value information of the measurement information management table for the past day is read for each server from the reception table storage unit 5e, and the average value is read. The arithmetic processing is performed. Then, the average value data is used as the first supplemental information image 53C. ₁ To enter. The second supplemental information image 53C ₂ Since the previous measurement value is input as supplementary information, the measurement value information of the previous measurement information management table is read from the reception table storage unit 5e, and the data of the measurement value is read as the second supplementary information image 53C. ₂ To enter. Subsequently, the CPU of the congestion situation drawing machine 5 develops and draws the supplementary information image to which the supplementary information is input in the memory in which the congestion situation image is developed (step ST17).
[0033]
Subsequently, the CPU of the congestion status drawing machine 5 reads the congestion status image and the supplementary information image from the memory by the transmission function 54B and transmits them to the client machine 4 (step ST17). Then, the CPU of the client machine 4 displays the received congestion status image and supplementary information image as a display function 4B. ₂ Is displayed on the display unit 4d as shown in FIG.
[0034]
As described above, by constructing this system, unlike the conventional example of displaying the congestion status based on the data capacity, how long it takes for the user to receive the desired service on the network. Can be grasped visually and properly. For this reason, for example, when the user is going to receive a plurality of services, the target service can be selected as appropriate depending on the congestion status, and the overall work time can be reduced.
[0035]
The measurement information management table 4C described above may be provided with a service detailed information column 44C in which detailed information on a service desired by the user can be input. In such a case, the above-described importance determination table 5D is provided with a service detailed information column 55D corresponding to the service detailed information column 44C of the measurement information management table 4C. For example, in the case of the Web server 1, the measurement information management table 4C shown in FIG. 2E in which the URL of the desired Web content is entered in the service detailed information column 44C. ₄ And the measurement information management table 5D shown in FIG. ₄ And provide. Thus, it is possible to grasp the congestion status for each Web content. Here, in the service detailed information fields 44C and 55D, for example, in the case of the file server 2, an identifier or the like for reading a desired file is accessed. In the case of the DB server 3, the desired database is accessed. The identifier or the like may be input.
[0036]
Next, a modification of the network congestion status display system will be described. The difference between this modified example and the above-described embodiment is that, although not shown, a congestion situation drawing machine is not provided on the system, and a function and a database related to this congestion situation drawing machine are provided on the client machine. Thereby, not only the same effects as those of the above-described embodiment can be obtained, but also an effect that the system can be simplified can be obtained. Specifically, first, the configuration can be simplified due to the absence of the congestion situation drawing machine. In addition, since the programs of this system can be integrated and, for example, the transmission functions 42B and 54B related to the programs are not necessary, the configuration of the programs can be simplified.
[0037]
【The invention's effect】
According to the present invention Network congestion status display system, display method, and display program According to the above, the user not only knows the congestion status on the network but simply “crowded” and “vacant”, but also how much the congestion is, that is, the service from the server node. You can see how long it takes to receive.
